  1. CTG Command, Telemetry, and GSE (CTG) Software Design Will Rachelson wrachelson@ssl.berkeley.edu

  2. CTG Topics • CTG relation to entire EFW SOC. • Interaction of CTG with SOC modules, modes of operation, data products. • Description of GSEOS and EFW extensions to GSEOS.

  3. CTG: Relation to Entire SOC

  4. CTG: Configurations and Data Products

  5. CTG: Bench Setup Signal is applied to the sensor sphere. The IDPU samples the signal from the sphere and sends data to the GSE laptop via the SCE.

  6. CTG: On-Orbit Setup

  7. CTG: GSEOS Screenshot

  8. CTG: GSEOS Out of the Box As-delivered to instrument teams. Needs instrument-specific customizations.

  9. CTG: GSEOS w/EFW Customizations These customizations fulfill the requirements for CTG outlined in the EFW SOC software requirements document. Requirements are verified according to procedures outlined in the test plan document, RBSP_EFW_SW-005-SOC-001.

  10. CTG: Logging Extended GSEOS with a central logging mechanism that records all session data into a single time-stamped directory. Data from these directories is transferred into the ARC module using rsync. This provides a backup copy of all test data.

  11. CTG: Scripting Example: There is a python file called ex05_commanding.py in the EFW scripts folder. To run it in GSEOS: >>> startscript(ex05_commanding) Scripting System Take Arguments, Return Values Capture all script-related commands, errors, events, etc., to the main EFW log file. Display current script execution status. Provide information about script coverage, visually and numerically. Complete execution trace logged.

  12. CTG: Test Equipment Control

  13. Summary The CTG module is a version of GSEOS specific to the EFW instrument. The CTG module sends commands to and receives telemetry from the EFW instrument, from early on-bench testing all the way through on-orbit operation. The same tool is used throughout the life of the instrument.
