Abstract

The DSN conjoint stations located in Spain and Australia have been operating with a tracking and telemetry simulation restriction. The Frequency and Timing Subsystem is able to provide either a real-time output or a simulation time output to the 64-m and 26-m station wings of the conjoint stations at any time, but not both simultaneously. During various tracking schedules, it is useful to be able to conduct a simulation run or training exercise with the non-tracking wing. This station utilization is restricted with the present system. The solution to this problem is to provide a separate real-time and simulation time interface to each of the two stations and to the three Telemetry and Command Processor strings. The simulation time switch assembly will provide the switching capability to drive independently the 64-m, 26-m, and processor interfaces with binary coded decimal time, 1 pulse per second, 100 pulse per second, and 1000 pulse per second Greenwich Mean Time (GMT) real time or simulation/tape time sources.
