If you've been under a rock for the past 50 years you might not have realized how much the visions of this man have changed your life. The most prominent would be the geosynchronous com satellite. There is a very high probability that nearly all of the cable TV you watch is from sat feeds, and of course DSS is all sat. Your GPS unit works via geo-sync sats. So does your sat-phone, if you've got some spendy need for one.
I hate to nitpik, but GPS satellites are not geosynchronus, rather they are circular orbital planes at 12,600 miles up. (They orbit about twice a day.) That said, the WAAS data is transmitted by geosynchronus satellite.
