COMSAT Participation in ARPA Packet Satellite Program (PSP)
Abstract
This final report summarizes the last year of the Communication Satellite Corporation's (COMSAT's) participation in the Atlantic Packet Satellite Program (SATNET), an experimental program involving packet data transmission via a single 64 Kb/s SCPC channel in the SPADE Transponder of INTELSAT IVA (Atlantic Primary) between standard A earth stations at Etam, W.Va. , Goonhilly U.K., and Tanum Sweden. A fourth, smaller (G/T = 28.5 dB/K) earth station at COMSAT Laboratories, Clarksburg, Md. also participated in the experimental network. The report describes new packet satellite program (PSP) terminals which were fabricated at COMSAT Laboratories for installation at the large INTELSAT earth stations. These terminals contain the necessary interfaces and modems to interconnect the SIMP (Satellite Interface Message Processor) and the earth station intermediate frequency (i.f.) equipment. Also described is the command and monitoring (C&M) module which is a part of the PSP terminal. Channel monitoring data collected during 1979 are summarized. Preliminary tradeoff result comparing packet satellite transmission to other alternatives are also included in the report.
