OPTIMUM SATELLITE DISPENSING VELOCITIES FOR AN EQUATORIAL HIGH ALTI

Abstract

Studies were made of the advantages of a communication system employing many active satellites in high altitude (15,000 to 30,000 miles) unsynchronized equatorial orbis over 24-hour synchronous and unsynchronized medium altitude orbits. The high altitudes provide: much better ground coverage than medium altitudes, low ground ANTENNA TRACKING RATES, LONG SATELLITE VISIBILITY PERIODS THUS AVOIDING THE RAPID GROUND ANTENNA SWITCHING REQUIRED WITH A MEDIUM ALTITUDE SYSTEM, AND THE POSSIBILITY OF LAUNCHING MANY OF THESE SIMPLE LONG LIFE SATELLITES WITH A SINGLE BOOSTER INSTEAD OF A SINGLE VERY COMPLICATED SYNCHRONIZED SATELLITE.
