Abstract
A telemetry simulation capability is provided at each Deep Space Station, by way of the Simulation Conversion Assembly (SCA), for testing station equipment and training of operations personnel prior to each mission. The simulation equipment provided to the DSN for support of the Viking 1975 mission has been substantially more complex than that provided for previous missions. No single station in the DSN has had the requirement to track three spacecraft simultaneously for any past flight project. Deep Space Stations will be required to support the equivalent of four spacecraft (two orbiters and two landers) for the Viking 1975 mission. However, any single station will have a view angle of the equivalent of only three spacecraft maximum at any given time (two orbiters and one lander). Since each spacecraft has two telemetry channels (one science and one engineering channel), the Deep Space Stations must be prepared to process six channels of telemetry data and hence a six-channel simulation capability must be provided. This entails the generation of an additional two channels of simulated telemetry data over the present four-channel capability of the Simulation Conversion Assembly. This article describes the SCA modification necessary to prepare for the Viking 1975 mission.
