ABSTRACT:
A paging/messaging system using the L3 transmission channel of a constellation of GPS satellites orbiting the earth, is comprised of an earth-based injection terminal having a source of paging/messaging signals and a radio transmitter for broadcasting paging/messaging on the L3 transmission channel to in-view ones of the constellation of GPS satellites. A plurality of earth-based mobile receiving stations, each mobile receiving station having an omnidirectional receiving antenna and an L3 transmission channel receiver for receiving the L3 transmission channel broadcasts from the in-view ones of the constellation of GPS satellites and demodulating and decoding to recover the paging/messaging signals, a display as used to present the paging/messaging signals to a designated user the recovered paging/messaging signals. At least one of said earth-based mobile receiving stations includes GPS position receiver for receiving GPS signals from the in-view satellites and determining the position of the mobile receiving station, and presenting the position information to the user on the display.
