This past week Jason Dunn, Chief Engineer for Omega Envoy, and Tapan Kulkarni, GNC Lead for Omega Envoy, attended the American Aeronautical Society's GNC conference in Breckenridge, Colorado to present a paper on the GNC Challenges for the Omega Envoy mission. In the paper several mission scenarios were presented which revealed our strategy for choosing the planned mission design to put our rover, Sagan, on the lunar surface. The paper also identifies the key GNC challenges that the mission will face. Future work will build off the mission design with more rigorous STK simulations incorporating the spacecraft CAD models and other geometric properties.
