Space-Based MA TTC System and Technologies

摘要

Multiple Access (MA) service provided by Tracking and Data Relay Satellite System (TDRSS) is a space based MA TT&C and communication service using satellite relay.Spaced-based MA TT&C system is specialized in the imple-mentation and application.In this paper the performance and technology devel-opment of S-band MA service provided by TDRSS is analyzed.As a feature of TDRSS SMA services,the major difference from that of conventional communication satellite is that its MA assignment has to be relayed and managed by ground station.Key technologies related to space based MA TT&C and commu-nication are determined and their implementation solutions are proposed.
