Abstract:

A method is described which allows the identification of favored beam distributions for multiple beam aeronautical satellites. It is used to synthesize beam designs and compare the capacities of two satellite system configurations which cover the major Pacific routes. The first configuration has two satellites with eclipse capability adequate for housekeeping and independent aircraft surveillance the second has additional battery capacity to provide 50 of the daylight communications capability in each satellite during eclipse. In this case, each satellite covers a limited portion of the full coverage area. Author
