As far as the numbers go, XM radio is beating Sirius for sheer number of subscribers. However, if you look at the recent subscriptions, Sirius is clearly gaining more subscribers than XM.

So which is better?

If the consumer’s dollar is a vote for the product they like, as economists suggest, then the consumer says XM was the better, but now Sirius is the top dog. The reason? The new Sirius S50, better talk radio involving Howard Stern and Martha Stewart grabbing both sides of the spectrum, and a bold new marketing campaign for their secret weapon the S50: “We Know What You’re Thinking”.

The slogan “we know what you’re thinking” comes probably from the way they researched the product: they hired a research team to follow people around and find a way to integrate Sirius radio into their lives. While many think it over-the-top to declare themselves psychic, the marketing worked perfectly: it got the consumer curious. Retailers around the nation are saying the reason for Sirius’ gains in momentum is clearly tied around the tiny handheld Satellite Radio player.

The player allows the user to set it in a docking bay and download the high-quality satellite radio recordings onto MP3 format and can be taken portably with you whereever you go. The Sirius S50’s size is about 4 inches by 2 inches, and the player weights roughly 6 ounces. Pretty amazing for the handheld “Sirius portable”, and the price of the object is placed at a perhaps sobering $280. Yet with their flurries of promotions such as rebates or other offers the weight is slightly lessened. That said, the legally free, high quality MP3’s definitely pay for the product

Aside from the new S50 we have all fallen in love with, Sirius offers a lineup of sports, talk radio, and critically praised music selections that is sure to sweeten the relationship. Also, a big positive aspect of Sirius is what it doesn’t have much of: negative consumer reactions. Sirius has very few satellite-to-receiver issues, whereas competitor XM’s receiver tends to have a volume shift now and then, which for me, has always been a big factor. Sirius, on the other hand, has crisp reception, even in some tunnels!

With the new Sirius S50, among all the other great advantages, it has become quite apparent that Sirius satellite radio is no longer the underdog. XM Radio better act quickly or they risk losing their leading status.

Free To Air Satellite Receiver systems provided a variety of niche programming for those seeking foreign language, ethnic, and religious programming.

There is some traditional television programming, but FTA satellite TV does not replace DirecTV, Dish Network, or your Basic Cable TV service. To get an idea of the type of programming available, review Their FTA Programming Chart. For most current Free To Air TV information, Free To Air uses the international MPEG2 Digital Video Broadcast (DVB) standard. DVB Satellite TV offers a better image quality, for most channels, this results in the best non HD TV you will witness. Free To Air Satellite Receiver Systems use a dish larger then your basic DirecTV or Dish Network dish, but generally always under 1 meter in size.

There are several receivers’ available and motorized mounts that allow users to take advantage of all the programming from various satellites, although more dishes are fixed on one satellite. A motorized mount is powered through the similar coax that carries the satellite signal from the dish to the receiver. The device located at the front of the receiver is called a Low Noise Block (LNB). The LNB lowers the frequency from the satellite frequency of 12 Ghz to a frequency appropriate for transfer over a standard RG-6 coax cable. More LNBS only provide a single receiver connection, but there are LNBS with two and even four coax connections. This allows for up to four receivers to be connected to a single dish only. Free To Air has involved over the last few years to include Digital Video Recorder (DVR) FTA Receivers and Multi-Sat dishes for simultaneous reception of up to 16 satellite orbits. The more common FTA receiver manufacturers are Pansat, Fortec, Coolsat, and the DVR FTA receiver from DreamBox.

While mostly used for access to religious and ethnic programming, Free To Air can appeal to almost every one looking to expand their television viewing options. If you don’t see the programming you desire you may find your satellite programming available from Globe Cast World TV, which offers subscription based international programming.

There are over a dozen Free To Air receiver manufacturers and the bulk of their business for years has been for the overseas and Europe markets. The DVB/MPEG2 format has been around for years and a better standard for satellite distribution. There are over 3000 free-to-air TV and radio channels available through out the world. With the correct size of dish their selection of FTA receivers will allow you to enjoy that programming selection. Many of these channels are foreign language channels from around the world. There are approximately 100 satellites that are available from around the world and available in North America. Various people of different nationalities want to listen or watch TV from their old homeland. Several ethnic cultures enjoy being connected with their heritage and that is why a free-to-air satellite receiver has been popular for years.

Sirius Satellite Radio is a service offering over 130 channels of satellite radio featuring digital-quality music, sports, news and entertainment programming when and where you want it.

They use a fleet of satellites to broadcast over 135 channels of satellite radio to listeners throughout the continental US and Canada.

Sirius Satellite Radio was previously known as Satellite CD Radio Inc.. The company changed its name to Sirius Satellite Radio Inc. on November 18, 1999. The name is derived from Sirius, sometimes referred to as the Dog Star, the brightest star in the night-time sky. The dog in the Sirius logo is unofficially named “Mongo”, a name garnered from the debut of Sirius Satellite Radio’s sponsorship on Casey Atwood’s and later Jimmy Spencer’s NASCAR entry, when the announcing cast voted on names. “Mongo” later became NASCAR driver Spencer’s nickname with the NASCAR Broadcasters (mainly Darrell Waltrip) in the following races.

Sirius Satellite Radio is one of two satellite radio services operating in the United States and Canada, along with XM Satellite Radio. Headquartered in New York City, with smaller studios in Los Angeles and Memphis, Sirius was officially launched on July 1, 2002 and currently provides 69 streams (channels) of music and 65 streams of sports, news and entertainment to listeners. Music streams on Sirius carry a wide variety of genres, broadcasting 24 hours daily, commercial-free. A few of Sirius music channels is included as part of the Dish Network satellite television service. Both Sirius Satellite Radio and Xm Satellite Radio Merged on Feb 10 2007

They also have loads of original programming. They host hundreds of exclusive live interviews and performances you won’t hear anywhere else and produce many interesting and engaging live talk shows in their national broadcast studios.

Some of the talk show host on Sirius Satellite Radio are Martha Stewart, Howard Stern, Tony Stewart,Jamie Foxx and many more.

To me this is Entertainment on demand you get to listen to whatever you want when you want and it is quality radio that is getting more popular by the day.

With most Sirius Satellite Radio enabled radios, the user can see the artist and song information on display while listening to the stream. The streams are broadcast from satellites in an elliptical geosynchronous orbit above North America.

Subscription costs for Sirius range from US$12.99 monthly (US$6.99 for multi-receivers) to US$499.99 for lifetime subscription. There is a US$15 activation fee for every radio activated.

The biggest difference is that Sirius Satellite Radio has 100% commercial-free music channels. What this means for you is that they offer you music the way it should be and the way the artist intended it: without a single commercial interruption.

Sirius Satellite Radio programming also has a breadth and depth of programming basically unavailable on regular radio. they play the songs that you know and love, and many songs that they know you’ll love when you hear them for the first time.

Sirius Satellite Radio also has partnered with names you trust like the NFL, NASCAR, NBA, FOX News, CNBC, NPR and ESPN to bring you the best entertainment available.

On October 16, 2006 Sirius Satellite Radio announced that it would be launching Sirius Internet Radio with 78 of its 135 channels being available worldwide on the internet to any of its subscribers with a valid user name and password.

Sirius Satellite Radio will launch its backseat television service exclusively in several DaimlerChrysler cars and minivans later this year three live child-themed TV channels would be available in 2008 model year cars in the Chrysler, Jeep and Dodge lines. Sales of those cars will start later this year.

Sirius Satellite Radio has been promising such a service since 2004, but at that time it said deals with manufacturers and content providers needed to be hammered out. Last November, Chief Executive Mel Karmazin said the service would launch in 2007.

The system will cost about $470, which includes the first year of service, when packaged with Chrysler’s rear-seat entertainment system in new cars. Customers must subscribe to Sirius Satellite Radio.

After that first year, TV service will be $7 a month in addition to the $13 a month for Sirius satellite radio.

Channels on the service include Viacom’s Nickelodeon, Walt Disney’s Disney Channel and Time Warner’s Cartoon Network.

Whan asked about some of the evening shows broadcast on Cartoon Network that are aimed at adults, a Sirius Satellite Radio spokesman said the 24-hour programming in the car will always be suitable for children.

He added that the service could be available in other carmakers’ vehicles beyond the 2008 model year.

The TV channels represent one of the last major programming thrusts by Sirius Satellite Radio, now that it has signed all the celebrity hosts, car agreements and high-level investments it needs to keep the accelerator on subscriber growth, Karmazin told Reuters in November.

Sirius Satellite Radio delivers the best 100% commercial-free music in virtually every genre. You will love it and now that Sirius and Xm are basicly one things will get even better.

You can find out about the portable options.

Satellite Internet is a form of high-speed Internet service which utilizes telecommunications satellites in earth orbit to provide Internet access to consumers.

A satellite Internet connection is basically an arrangement in which the upstream (outgoing) and the downstream (incoming) data are sent from, and arrive at, a computer through a satellite. Each subscriber’s hardware includes a satellite dish antenna and a transceiver (Modem) that operates in the microwave portion of the radio spectrum. Your computer, through the satellite modem, broadcasts requests to a satellite dish antenna that sits on top of your home or business. The dish antenna then sends and receives signals from satellites that orbit some 22,300 miles above the equator. As long as your dish maintains a clear view of the southern sky (in the U.S.), you receive broadband Internet access. Currently, satellite broadband is slower in both the uplink and downlink, when compared to a DSL Internet service, for example.

Satellite Internet services are of two types. One-way service uses DVB-IP (Digital Video Broadcast- Internet Protocol), which is only for inbound connectivity. Hence, one way service is ideally suited for webpage viewing.

Two-way services provide complete broadband services to the users. Two-way service enables high-speed access for both download and upload. This platform is ideal for home, offices and small and medium enterprises. In this two-way satellite Internet connection, the upstream data is usually sent at a slower speed than the downstream data arrives. Thus, the connection is asymmetric. The upload speed will always be slower than the download speed. A dish antenna, measuring about one and half feet high by three feet wide by three feet deep, transmits and receives signals. Uplink speeds are variable and nominally 128 to 500 Kbps for a subscriber using a single or multiple computers. The downlink occurs at speeds ranging from about 700 Kbps to 2000 Kbps, depending on factors such as Internet traffic, the capacity of the server, the sizes of downloaded files and upon the plan provided by the service providers.

Satellite Internet systems are an excellent option for people in rural areas where Digital Subscriber Line (DSL) and cable modem connections are not available. Now, because of technical development it becomes a good option for urban subscriber also who needs high speed Internet. A satellite installation can be used even where the most basic utilities are lacking, if there is a generator or battery power supply that can produce enough electricity to run a desktop computer system. The two-way satellite Internet option offers an always-on connection that bypasses the dial-up process. In this respect, the satellite system resembles a cable modem Internet connection. But this asset can also be a liability, unless a firewall is used to protect the computer against hack attempts.

The nature of the satellite internet connection is good for web browsing and for downloading of files. Because of long latency compared with purely land-based systems, interactive applications such as online gaming are not compatible with satellite networks. In a two-way geostationary-satellite Internet connection, a transaction requires two round trips between the earth’s surface and transponders orbiting 22,300 miles above the equator. This occurs in addition to land-based data transfer between the earthbound satellite system hub and the accessed Internet sites. The speed in such a connection is theoretically at least 0.48 second (the time it takes an electromagnetic signal to make two round trips at 186,000 miles per second to and from a geostationary satellite), and in practice is somewhat longer. Satellite systems are also prone to rain fade (degradation during heavy precipitation) and occasional brief periods of solar interference in mid-March and late September, when the sun lines up with the satellite for a few minutes each day. Rain fade and solar interference affect all satellite links from time to time, not just Internet systems.

So now there is an amazing internet service called broadband satellite Internet services for those who can’t get a cable to their home or office or for those who have no access to DSL. It provides a super-fast, independent 2-way duplex, always-on Internet connectivity that delivers flexible, IP-based services on a single platform.

All agencies with Satellite Internet services utilize the same technology, but have different pricing packages and customer service. But, if you talk about pricing packages, better internet services and customer services, the HughesNet® is one of the best among all.

· Captiveworks CW600s is a premium FTA receiver whereby it includes video output devise, digital optic output, universal remote, and has seven days electronic program guide. This FTA receiver likewise has faster conexant processor.

The above FTA receivers are only a few of the most recommended FTA receivers from among the wide array of choices. Thus, before you shop for your FTA receivers, it may help to ensure that your supplier will provide for file support that will be available 24/7. This is to ensure that you will be assisted when the need arise.

Having the FTA receiver and the file support is only one step. You will also need to have a satellite dish to connect to the satellite you wish to connect to.

Satellite dish

Most FTA programs are broadcast on C Band or 6-foot satellite dish. However, migration to Ku Band satellite dish or those satellite dishes that measures less than one meter is getting to be popular. Thus, many FTA viewers use Ku Band system.

You already have your satellite dish, your FTA receiver and file support, you may also need a rotor or antenna motor.

Antenna motor

The antenna motor or the so-called rotor will search for satellites and will connect to more than one satellite. This will help you enjoy the more than one hundred FTA channels and digital programs coming from various parts of the world.

Countries with FTA broadcasting

· Australia

· India

· Europe

· New Zealand

· North America

FTA programs are broadcast in their local dialect. Therefore, if you are from any of the above areas and you migrated to another country, you will be able to view programs in your new location coming from your country of origin.

Being multilingual will likewise ensure that you will enjoy the FTA programs.

Of course, your FTA receiver will play a big role in ensuring that you will be able to view the programs well. I recommend that before buying FTA receivers, you shop around and choose the best. Know what you need and choose the best that fits that need.

Since the beginning of Radio’s inception, no one has dared to arrest people who copy songs from the radio.

RIAA, the Recording Industry Association of America, now dares.

They have banned Sirius from allowing more than one downloadable song per download. The only reason for this is because the Satellite radio songs are just as good quality as MP3, thereby eliminating the need to buy the MP3’s.

RIAA has now pushed legislation through the house “to protect content delivered through high-definition (HD) radio receivers”. What that means, is anyone using a HIGH QUALITY method to copy a song is in violation of the law. But if you use a low-quality method; say, a cassette, then it’s okay.

Where is the logic in that? Aren’t laws a reflection of moral values? So it’s moral to copy a song onto cassette, but immoral to copy it onto a MP3 player?

Something is insanely illogical about that concept. RIAA claims musicians can’t make money if their songs are all downloaded illegally.

Only a century ago, there wasn’t a police force that prevented anyone but the original composer from playing their music in the streets. If Beethoven wanted to make money, he had to play in a concert for the people. He couldn’t just kick back and earn money every time a fiddler in the street played a tune from his concerto.

So what holds water about the RIAA argument? Very little in terms of historical legitimacy, and even in modern times, musicians are pulling in record numbers from concerts. The Rolling Stones pulled in over $162 million in 2005 from tours. Green Day pulled in $39 million, and Dave Matthews raked $31 million, with significantly less touring than the Stones. Is that not enough?

Even Paul McGuinness the manager of U2 said, “Our recording income is not insignificant, but it’s less than we make from touring. The figures used to be closer together.” U2’s 2005 tour pulled in $139 million.

So with concert income rising grotesquely, does the RIAA even have the right to push its legalistic agenda? Ironically, the spread of free music has encouraged music listening far beyond paid music: the increased availability of music has lead to increased concert-going fans as the record-breaking tours indicate.

With concert rates rising, and the income disparity from concerts and recording sales, perhaps RIAA should consider their nefarious designs at deciding what is Right and Wrong. Like a master teaching his dog manners, RIAA tells the consumers: Record radio on a cassette, good. Record radio onto MP3, bad dog, Sirius gets a time-out, and the critically acclaimed S50 is the first casualty in the war for consumer rights against RIAA.

In so doing, since the Sirius S50 was owned by hundreds of thousands, the RIAA has essentially destroyed the value of a product that did not belong to them. Without a moral basis for doing so, that is where the true immorality lies.

Maybe if the public starts downloading satellite radio music onto CD, then RIAA will help get CD recording of radio will be banned too.

It might be a relatively new outgrowth of the satellite age, but that isn’t stopping subscription-based radio from offering some serious advantages over regular FM and AM bandwidths.

Providing listeners more choice than they could ever imagine, services like Sirius satellite radio are to the airwaves what cable was to television not too terribly long ago.

These services work in much the same manner as cable television, too. Potential listeners need to subscribe and obtain special receivers to be able to tune into programming. The subscription fees are generally fairly low on these services considering the options they provide. Receivers are generally made available for automobiles, homes and even offices. Some providers offer receivers that are portable, so satellite programming can go anywhere the owner does.

Sirius satellite radio is just one provider taking advantage of this technology to deliver subscription-based programming to vehicles, offices and households all over the country. The advantages of satellite radio over basic FM or AM stations are pretty amazing. The pros include:

Syndicated shows: With lots of major radio personalities all over the country jumping on the satellite radio bandwagon, favorite shows from Boston to Los Angeles are starting to appear on subscription stations. This means listeners have lots of choice in talk shows, sports programming and more.

Lack of censorship: The censoring on outlets such as satellite radio tends to be limited, which means listeners hear songs and programs as they were intended. While this isn’t always great for those with kids in the car, it is for those who abhor songs and comedy routines being altered to fit a censor’s whims.

Variety of music: With so many different channels at their fingertips, Sirius satellite radio subscribers find they can listen to just about anything. From the classics to the classical and beyond, the variety provided by satellite is simply fantastic.

More news: Some people tune into packages like satellite radio simply for the news programming. Offering more stations than regular radio could ever hope to, these services provide up-to-the-minute reports on a variety of news channels. It’s even possible for people living in major markets to hear local news as it happens.

Comedy: Make no mistake, this is one of the big draws for programming offered by providers such as Sirius satellite radio. With a variety of comedy stations, subscribers can hear the latest stand up routines from comics from one coast to the other.

Traffic: One of the biggest perks found in satellite radio is the on-time traffic reporting for most major metro areas. This means all it takes is tuning in to find out how the drive home is going in a person’s own hometown or across the country.

While it does come with a subscription fee, Sirius satellite radio is the choice of many because of the variety of listening options it provides. The choice, reception and portability offered by satellite providers helps these type of services beat regular FM and AM stations hands down. This type of satellite service has quickly become to radio what cable was to the television not too long ago.

You have probably been hearing about satellite radio for a while and of course, lately there has been plenty of news about Howard Stern, he is bringing in many listeners to Sirius and the fan base is growing quickly.

One of the big differences between regular radio and satellite radio is that with satellite you get hundreds of channels that are of digital quality, plus on the screen you know who is performing because it gives you that information. There are very few channels on satellite radio that have commercials. With over 100 channels to choose from there is always something good to listen to. No commercials just the music you want to listen to , you don’t have to listen to salesmen, fuel companies, food advertisements, you will have no static, you will be able to listen to your music or talk show with no interruptions 24 hours a day. There are so many channels; a few of them are comedy, local weather and traffic, women’s issues, sports, old time talk shows from the 20s to the 40s.

Through digital magic, you will not get static or any other types of disturbances you would normally get from an analog radio. The possibilities do not end there though, as it may even be possible for digital stations to broadcast pictures and videos directly to your car or home stereo through the magic of digital broadcasting. When receiving a signal from satellite the signal is completely digital and everyone knows a digital signal sounds cleaner and there is no static, you either get the signal or there is not signal. The signal is encoded and sent to the satellite and then it is sent back down to a receiver which it will be decoded and then the receiver plays the sound. If you find you loose the signal it is because when you travel you move along the earth and since the earth is round you will sometimes loose the signal because the satellites are traditional on the horizons.

Now, people you don’t need to switch stations when driving because you cannot get a clear station in, you can listen to the same station or hundreds of other stations ranging from news, music and news in better quality than AM or FM bands. To receive the digital audio streams you will need a antenna to receive the signal.

Its small, portable and it fits in your purse or pocket, don’t be fooled because they are small, they give the best sounding quality a radio can offer. The auto manufacturers are installing satellite radios to enhance the new automobiles, and many stores are now carrying the portable models to be used in the homes.

Satellite radio is subscription based, meaning that you pay a monthly fee for the service. The purchase of a satellite radio and a small monthly fee will open a whole world of ad-free radio listening to you. You will need to pay a monthly or yearly subscription fee to enjoy satellite radio. Many of the automobile dealerships and manufacturers offering many different types of incentives, so are giving 3 months free or even up to 6 months of free service to get you hooked, they are also throwing in no activation fee.

Most of the FTA transmissions are on the Ku Band frequency range and the Ku band operates between 12 Ghz and 14 GHz, which permits today’s smaller dishes from 18 inches to 31 inches in diameter and before the Ku band, the C band was the first to be developed for satellite television which operated between 3.4 Ghz and 7 Ghz. The old dishes used to pick up these signals earlier were 20-30 feet wide and now they have been compressed to 6 feet.

Telemetry or “remote measurement” is a highly automated communications process by which measurements are made and other data collected at remote, inaccessible or dangerous places, and then relayed by a telemetry transmitter to receiving stations for display, monitoring, and recording.

The original telemetry systems were termed “supervisory” because they were used to monitor electric power distribution. Communication channels form a major part of any telemetry system, as it involves measurement of the transmission of data over various mediums.

Telemetry transmitter is the instrument used for recording the readings of an instrument and transmitting them by radio or wireless frequencies. Technically, when relaying data, it is necessary for the transmitter to identify the data item corresponding to each segment of the bit stream. This is done by inserting a synchronization bit string into the telemetry stream on a regular basis, usually at the beginning or end of each repeating cycle. This generally corresponds to the beginning or end of a minor or major frame of telemetry data.

Aerospace telemetry initiated in the 1930s with the radiosonde, a instrument that automatically measured atmospheric temperature, pressure and humidity by means of a small, expendable telemetry transmitter from a balloon high in space, and relayed the data back to Earth using radio signals. These days, telemetry is used in testing of moving vehicles such as cars, aircrafts, missiles and satellites. National Aeronautics and Space Administration (NASA), European Space Agency (ESA) and other international space agencies use telemetry transmitters for data collection and transmission from orbiting spacecrafts and satellites.

Wireless networking without the encumbrance and restriction of wires connecting the transmitter and receiver has catapulted the potential applications of telemetry. Major applications of telemetry includes automatic monitoring of large, complex systems such as satellites, chemical plants, oilrigs, electric power plants, gathering meteorological data, remote meter reading, logistics management, tracking endangered land and marine species, real time physiological monitoring of patients, and monitoring manned and unmanned space flights.

Winston Churchill once said, “The price of greatness is responsibility.” In the same manner, this great technology should be used responsibly. For instance, for many environmental monitoring duties, such as stream gauging or automatic weather stations, the measurement values are unlikely to change significantly for many hours at a time. In such cases, it would be grossly uneconomical in terms of both electrical power and use of spectrum space to run the telemetry transmitter continuously. On the other hand, constant monitoring by medical uses of telemetry is often necessary in order to detect problems as soon as they arise.
