The television we watch at home, the weather updates we receive, the knowledge we acquire of other planets in the universe, are all possible due to satellites. Artificial satellites are man-made objects that orbit the Earth. These satellites are launched for specific purposes. A satellite is lifted from the earth’s surface by a rocket and, once placed in orbit, maintains its motion without further rocket propulsion. The first artificial satellite, Sputnik I, was launched on Oct. 4, 1957, by the USSR, which triggered the space race between the Soviet Union and the U.S. The first U.S. satellite, Explorer I, was launched on Jan. 31, 1958. During the first decade of space exploration, satellites were launched from either the United States or USSR. Today, there are more than three dozen launch sites in use or under construction in more than a dozen countries.

If you are a corporation in search of disaster recovery networking solutions, a first responder who may need connectivity from anywhere at any time, or you simply need broadband internet connectivity from remote locations you have probably considered that satellite may be your only reliable option. In the midst of a disaster many businesses and first responders may find themselves without communications of any kind due to the loss of terrestrial infrastructures, or the lack of it ever existing in the first place.

One of the biggest pass times in the world is watching television. For 60 years and more the world has had entertainment at their fingertips inside their own homes, where as before television we entertained our selves, had to go out to watch a movie at a theatre, or we might have had a radio to listen to. When television came into our homes it was literally a whole new world.

Are you happy with your current satellite TV subscription? Are the available channels enough to satisfy your growing demand for entertainment and the latest news? Well, I guess you should be because, like me satellite TV was like a gift from heaven. It answered my prayer for endless entertainment and news 24 hours a day. Except for its monthly subscription rate, satellite TV was all good. Which is why, satellite TV subscription rates and demands have been growing steadily over the past few years all over the world. However, technology has once again proven that nothing is impossible because with a new state-of-the-art piece of software application, it is now possible to watch satellite TV on PC. We will review some benefits for anyone who intends to use this state-of-the-art software application.

Satellite radio becomes more and more popular. It is a choice of millions and the army of listeners is still growing. Three provider companies offer this service: XM Satellite Radio and Sirius Satellite Radio broadcast throughout the United States, Canada and Mexico and they are the major players on the market. The third one, WorldSpace, broadcasts to the rest part of the world (Europe, Asia and Africa). Each of the providers offers more than a hundred of entertainment and music channels, talk shows, sports games and many more. It also includes adult-oriented broadcasting, since FCC (Federal Communications Commission) does not regulate the industry. So, there’s something for everyone.

I have been working in the Satellite business for the last 10 years. I don’t assume I know everything, but I know quite a bit about Satellite TV. Even until this date, I still get asked, what is the difference between Express Vu and Star Choice Satellite systems in Canada.

Believe or not, both companies offer about the same channels. In fact, over 95% of the channels are the same. Also, their prices are quite competitive in the Canadian market. So, if that’s the case, what makes a person choosing one satellite company from the other one? The answer is very simple: Features and Gadgets.

Are you a music fanatic? Do you love your tunes? Do you hate interruptions by commercials, news and other public service announcements while you are trying to enjoy your favorite music? With Sirius Satellite Radio, you can have the best of the music world. A constant stream of your favorite music presented free of commercial interruption brought to you by satellite.

Whether you want to listen at home, or if you spend a lot of time in your car, the Sirius Satellite Radio is perfect. This radio can either be hardwired into your car’s stereo system or it can be set up in your home. Either way, you will have an antenna that will receive music signals from a network of satellites.

Once you have ordered your new satellite TV system your will need to install it. Now you have the option of letting a professional do it for you or installing your own satellite TV system. Here is how to do your own installation.

Here is a step by step guide to satellite TV installation:

1. First, you will need to mount your satellite dish – you can mount it on your roof, on a balcony, or on a south-facing wall. Make sure the location you pick has no tall buildings or trees nearby.

Navigational satellites were one of the early applications of artificial earth satellites. Very early in the space age, researchers realized that satellites could be put on orbits to permit ships, aircraft, or other vehicles to exactly determine their locations. Global positioning systems (GPS) make of navigation satellites. The GPS constellation system was first established by the US military to support of their forces. But it is now in widespread in public and commercial applications.

The navigation equipment generally consists of a sensitive radio receiver, an accurate frequency reference, and an accurate clock. The idea of using satellites for navigation began with the launch of Sputnik 1 on October 4, 1957. Satellite navigation systems allow small electronic devices to determine their location.

Satellites fall into five principal types - research satellites, communication satellites, weather satellites, navigational satellites, and application satellites. Communication satellites provide a worldwide linkup of radio, telephone, and television. The first communication satellite was Echo 1, launched in 1960. Relay 1 and telstar 1 were the first active communications satellites. They were launched in 1962. Telstar 1 transmitted first live television broadcast across the Atlantic.
