ODTK CAPABILITIES

Support and Simulate Mission Design and Planning

Promote early phase mission design and planning, trade studies, proposals, or internal research. Simulate predicted orbit accuracies for a proposed mission to ensure that it is flyable—process spacecraft tracking data to navigate accurately and confidently on live missions. Integrate into a flight dynamics system for hands-on or lights-out operations—endorse landing operations on other bodies, such as the Moon or Mars. Geolocate ground emitters—containerize for cloud deployment.
