All of them have an onboard computer to control and monitor the different systems. All have a radio system and antenna. At the very least, most satellites have a radio transmitter/receiver so that the ground-control crew can request status information from the satellite and monitor its health....
as well as their budgets, have tended to get bigger. The United States, for example, has spent $200 billion on its military satellite program since its inception and now, despite the investment, has a fleet of aging devices without many replacements waiting in the wings [source:The New Atla...
To place a satellite in a stable orbit around Earth, it must overcome Earth’s gravitational pull and air resistance in the lower atmosphere. Theescape velocityfor a satellite is around 7 miles per second. Even after escaping Earth, the pull of gravity contests a satellite’s tendency to rema...

A detailed guide on how a small satellite dish on Earth communicates with geostationary satellites orbiting 22,300 miles above the equator.
location. For example, if you want the Virtual Advisor to give you a weather report, you simply say "Get my weather" and the advisor reads the weather report for your area. Virtual Advisor uses pre-paid minutes and may not work with the Verizon plan, depending on the model of your car...
In this article, we'll peer into the guts of a typical satellite and then gaze through its "eyes" to enjoy views of our planet that Socrates and Newton could have barely imagined. But first, let's take a closer look at what, exactly, makes a satellite different from other celestial obj...
To know how many satellite have been acquired, place the gps sats element in your OSD. 6-8 is the minimum for rescue mode to work, the more the better. Your GPS coordinates will also get more accurate when you acquire more satellites. ...
A GPS receiver has to have a clear line of sight to the satellite to operate, so dense tree cover and buildings can keep it from getting a fix on your location. GPS receivers and cell phones have a lot in common, and both are very popular. In the next section, we'll look at some...
