There are a number of primary space research service (SRS) allocations that can be used by deep-space missions for telecommand, telemetry, and radiometric data collection. Some of these allocations are designated specifically for deep-space SRS missions and are not available to non-deep-space SRS missions, while other allocations are available to both deep-space and non-deep-space SRS missions.
