This Standard addresses the utilization of telecommand packets and telemetry packets for the purposes of remote monitoring and control of spacecraft subsystems and payloads.
This Standard does not address missionspecific payload data packets, but the rules contained herein can be extended to suit the requirements of any mission.
This Standard does not address audio and video data as they are not contained within either telecommand or telemetry packets.
This Standard defines a set of services that satisfy all the fundamental operational requirements for spacecraft monitoring and control during spacecraft integration, testing and flight operations, refer to ECSS-E-ST-70-11. It also specifies the structure and contents of the telecommand packets used to transport the requests and the telemetry packets used to transport the reports.
This Standard can be used by any mission, no matter what its domain of application, orbit or ground station coverage characteristics. However, it is not the intention that the PUS should be applied in its entirety to a given mission. The services defined in this Standard cover a wide spectrum of operational scenarios and, for a given mission, only a subset of these services is likely to be appropriate.
