Scientific American, April, 1998, Volume 278, Number 4, Special Report: The Unwired World: pp. 70-77, "New Satellites for Personal Communication," by John V. Evans. You've got to buy a copy of this issue. The website, while it carries this issue, does not have the special report onboard. Ellipso and ORBI mentioned throughout as well as Motorola, Qualcomm, MCHI, CCI, Globalstar, Iridium, Loral Space and Comm, etc. "Higher Orbits,": The two personal communications satellite systems that will be based on satellites in orbits higher than low earth orbits (LEO) are ICO Global Communications, and Ellipso. The Ellipso system, uniquely, will use satellites in elliptical orbits designed to take advantage of the fact that most of the world's population lies in the Northern Hemisphere. That is, an orbit is chosen that has its farthest point from the earth (the apogee) above the Northern Hemisphere, allowing the satellite to spend more time north of the equator. Systems builder MCHI intends to have its satellites built by Orbital Science Corporation in Dulles, VA. This is a tiny excerpt of the article and deserves to be fully read. Also on p. 92, "Moving Beyond Wireless Voice Systems," by Warren Stutzman and Carl Dietrich, the article addresses GPS. tcd
