width=October 23, 2018: The Core Operations, Mission Planning, and Analysis Spacecraft Simulation (COMPASS), a joint development effort between JSC and JPL and supported by Odyssey Space Research, has recently passed an Operational Readiness Review for AA-2. The software will be used by the Flight Dynamics and Operations Group in NASA’s Flight Operations Directorate to perform Range Safety analysis and to generate data products for this important test of the Orion Launch Abort System.

Development of the next release of the software, which will undergo safety critical certification, is currently underway. Successfully completing this certification will allow the COMPASS software to be used to generate Day-Of-Launch I-Load Updates (DOLILU) for the EM-1 mission. These updates customize the vehicle steering commands for the current environment and verify the integrated vehicle trajectory’s loads, controls, and performance just prior to launch.
