21 THEMIS IDPU FSW 6/23/2016 21 UCB P3 SIM RESULTS Simulated Pass is too short to remove 375 Mb at GSE Rate 5

22 THEMIS IDPU FSW 6/23/2016 22 UCB P3 SIM RESULTS

23 THEMIS IDPU FSW 6/23/2016 23 UCB ISSUES P3 SIMULATION RESULTS and ISSUES 1.Too Much RAW Data Being Generated 453 (MOMENTS) occurring every spin –CANNOT Cut Down the Rate –4-byte Data Instead of 2-bytes, 212 Bytes Every Spin –FSW Compressor/Decimator Needed 451 (TRIGGER) occurring every second –Reformatting to remove filter data (will cut to ¼ volume) in V4.01 –Remove 451 during Slow Survey –Need a budget. What’s a reasonable amount to save and replay? 452 (SST Engineering) –Not accounted in the total data budget (Vassilis’) –Not a whole lot of data, can be cut another factor of 4 or eliminated. 2.Compression Works Well (>2.5 ratio) 3.GSE Does Not Handle Telemetry Fast Enough in 30 minutes to remove 375 Mbits Extend Pass in order to get this done 4.Need Shadow Entry and Exit Scripts 5.Need Solar Wind Entry and Exit Scripts New EEPROM Loads Required to Make EFI, SST and ESA Work in Solar Wind FSW Able to Load from Multiple EEPROM Directories (have not yet tried this!)

24 THEMIS IDPU FSW 6/23/2016 24 UCB PLAN 1.SST/ESA MOMENTS Decimation Specification – Completed and Approved FSW Developed and Test – Completed GSE Software Modification – Jim Lewis Splitter Software Modification – Jim Lewis 2.SST/ESA REFORMATTING (ETC Version 5) New FSW Support to Start New Directories – SST/ESA ReTest – Cannot be Done on ETU
