Page 10GS CDR May 2005 Telemetry Data Archive Telemetry data is archived twice The Data Capture System archives tlm files for offsite storage Archive tapes are shipped to the offsite location and verified for reading A feedback mechanism will be established to ack the SDP that a tape is verified or that another copy needs to be sent The Data Capture System copies tlm files to the Pipeline Processing System The Pipeline Processing System archives tlm data for local storage and acks the SDP when it is successful Only when the SDP has received positive acks on both archive copies does it inform the Data Capture System to include the tlm file in the.arc file to the DDS, who is now free to remove the file from its tracking logic The lev0 data on the Pipeline Processing System is also archived

Page 15GS CDR May 2005 Test Approach Telemetry data is simulated with MDI data packaged in SDO VCDUs Various telemetry pathologies can be created to validate telemetry processing The DDS is simulated by packaging the VCDUs into files and injecting them into the SOC front end using the DDS/SOC protocol The lev0 processing is validated by comparing input and output images Timing analysis and throughput studies will be performed to evaluate h/w and s/w tradeoffs Instrument sunlight tests will be used to validate the lev1 processing Each s/w library and subsystem has a regression test suite that is run to verify each new CM release Full end to end testing is accomplished via the mission I&T plan
