There is a Directv satellite at your fingertips. In fact, there are 1,000 of them. The Directv satellite system gives you access to 1,000 TV satellites circling the earth’s equator. Actually, not all of these satellites are part of this system. Enough of them are, however, to give you choices of hundreds of TV channels. TV satellites orbit the earth’s equator at an altitude of 22, 223 and at a speed of 7,000 mph. This is the altitude and speed required to keep these satellites in a geostationary orbit. This means that our Directv satellite is staying directly above the same spot on the earth’s surface at all times. By staying in a geostationary orbit, TV viewers on earth receive a consistent signal from the same satellite or set of satellites. Click the button on your remote and the TV set comes on. Instantly this activates the descrambler unit in your satellite TV receiver to unscramble encrypted signals rebroadcast from the Directv satellite. The image you are seeing and the sound you are hearing is being broadcast from earth to this satellite far above the earth and then sent back to earth to your TV receiver. All of this takes place with incredible speed as well as picture and sound quality. And, all at the click of a button on your remote. People click the remote control buttons and enjoy their favorite programming. They never wonder about the wonderful technology involved in the Directv satellite system. Understanding the system is not important. What is important is appreciating the miraculous inventiveness of the human spirit and the benefits we enjoy because of it.
