Earth Reception Time minus the propagation delay (applicable to spacecraft TM only) The packet is time-stamped with the time of transmission of the frame it was received in, i.e. Packet is time-stamped with the creation time – i.e.
Simulated packet generated by a Simulator or test tool. Non-simulated packet generated by the spacecraft Note: For TC packets, SPIDs 100 and 200 are used.įor telemetry, the MCS mission identifier. The numerical packet ID which identifies the packet structure, and maps to packet definitions in the TM/TC MIB database. Internal MCS counter used for detecting gaps – not related to the spacecraft source sequence count value in the PUS header. The datastream identifier in the MCS, which for TM maps to VCs. Time quality of the timestamp, used only if the TsPolicy is set to 2. what will be set in the Filing Time fields above. Set to : 1 if this packet is to be distributed to the MCS applications, otherwise 0.ĭetermines the timestamp policy for spacecraft TM, i.e. Set to 1 if this packet is to be filed in the MCS archive, otherwise 0. Size of the entire SCOS-2000 packet, including all headers and the packet data.ĭetermines the type of SCOS-2000 packet. In the case of telemetry, the ID and name of the ground station which receives the frame containing this packet. Used by the old SCOS-2000 archive for generating a retrieval key and set by the application which generated the packet. For TCs, this is its (estimated) execution time. This is a secondary retrieval key and for TM is the time at which the SCOS-2000 packet was created, which is also approximately the time that the packet was received by the MCS and stored. For TCs, this is the release time.Ĭreation Time. Simulated packet, see Simulated Packet Tableįiling Time. Used in earlier version of SCOS-2000 by c-tree to support packets storing in files and be kept for backward compatibility. In the CHP are present the following fields. SCOS import SCOS, MissionID, SpacecraftID MissionID = ad is reported in the tables. For example to add the JUICE Mission : form SCOS. It is possible add a new Mission ID and Spcecraft ID. LimitationĪt the moment the software works only for Telemetry and Telecommand packets (Packet Types 1 and 2) for the BepiColombo ESA Mission. Where packet is the hexadecimal string rapresentation of the Telemetry packet. Usage from SCOS.SCOS import SCOS a = SCOS ( packet ) SCOSpy is a python library for the Satellite Control and Operation System 2000 (SCOS-2000) header written as hexadecimal string.Ĭurrent version is 0.4.4 Library Installation $ pip install SCOSpy
