Test(s)

011: GRB Handling/Repointing Requests

This test shall verify that the SIU FSW correctly handles and responds to GRB alerts and repointing requests from both the ground and the GBM (via the SC). Verification shall include a variety of scenarios, including repointing enable, different operational modes, and conflicting requests. The test shall verify that the SIU FSW responds to these alerts and requests properly, rejecting the appropriate ones and forwarding repointing requests to the SC for the other cases.
