GPS alternate signal structure for civil use
Abstract
The structure of the NAVSTAR Global Positioning System (GPS) signal is examined for possible modification from the point of view of cost, reliability, and operational characteristics. Two signal candidates are considered: the GPS signal with increased power and TDMA signal. It is noted that a TDMA technique permits high peak powers and short pulses which eliminate Doppler effect. It requires low average transmitted powers and allows rapid representation of data from all visible satellites.
