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.

CTG: Relation to Entire SOC

CTG: Configurations and Data Products

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.

CTG: On-Orbit Setup

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

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.

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.

CTG: Scripting Example: There is a python file called ex 05_commanding. py in the EFW scripts folder. To run it in GSEOS: >>> startscript(ex 05_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.

CTG: Test Equipment Control

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.
