LAT Level Requirement Sell-off Package for
LVP83/LPS503 – CCSDS Telecommand Standards
Requirement Owner: Rich Baun
Approval Date:
Approved By:
LAT Docs No: LAT-MD-xxxxx

2. LVP83/LPS503 – CCSDS Telecommand Standards (1 of 2)
Requirement:
The LAT shall employ the Consultative Committee on Space Data Systems (CCSDS) standard for telemetry and telecommand.
Verification Method: D5
Verification Plan:
1) In test cases LAT131 - LAT Config 1 LAT/SC Interface Functional and LAT132 - Config 2 LAT/SC Interface Functional demonstrate the LAT is using the CCSDS standards for command and telemetry by: 1) By issuing CCSDS formatted commands from the VSC to the LAT and verifying with telemetry that those commands execute; and 2) Receiving CCSDS telemetry packets via the VSC from the LAT and decommutating those packets into meaningful telemetry data.
2) In test case LAT141 - LAT Config 1 LAT/SC Interface Functional with the SIIS demonstrate the LAT is using the CCSDS standards for command and telemetry by: 1) By issuing CCSDS formatted commands via the SIIS to the LAT and verifying with telemetry that those commands execute; and 2) Receiving CCSDS telemetry packets via the SIIS from the LAT and decommutating those packets into meaningful telemetry data.
