Abstract:
Prior to the redirection of the Constellation Program, the Wallops 11.3-meter ground station was tasked to support the Orion’s Dissimilar Voice (DV) link and the Ares’s Development Flight Instrument (DFI) link. Detailed analysis of the launch trajectories indicates that during the launch and ascent operation, the critical events of Orion-Ares main engine cut off (MECO) and Separation occur at low elevation angle. We worked with engineers from both Wallops Flight Facility (WFF) and Johnson Space Center (JSC) to perform an intensive measurement and link analysis campaign on the DV and DFI links.
