PASSIVE SPHERICAL SATELLITE COMMUNICATIONS STUDY
Abstract
The terminal equipment specifications presented provide the traffic handling capabilities for ground stations operating within a proposed passive satellite communications network. These stations will vary in size, depending upon the amount of traffic flow and the number of links served. The nature of the transmission medium poses several problems, including: a variable length transmission path, an instant of transfer of communications from a setting satellite to a rising satellite, and the handling of traffic in the several forms of voice, graphics, teletype, and data. It is proposed that all traffic be handled in digital form once it enters the system and that transmission on each link be in the form of a time-division multiplexed serial binary stream. To correct for the variable length transmission path, the bit train is reclocked at the receiving end of each link. At the ground station, traffic is separated into real-time (voice and graphics) and store-and-forward (data and teletype). The two forms are processed through separate switching centers and recombined for transmission on the next link. Equipment is specified and cost estimates are given.
