Operationally Proven Spacecraft Navigation Software

Highly accurate orbit estimates and pre-flight simulations reduce costs and optimize resources.

Ansys ODTK provides highly accurate orbit estimates. Run preflight simulations to evaluate proposed tracking methodologies, reducing costs and optimizing resources while meeting mission requirements. Visualize your results in customized output products using the embedded reporting and graphing capability. With ODTK’s state-of-the-art optimal sequential filter and matched smoother, meet your most stringent mission requirements. Use ODTK’s automated interface to simplify operator workflows or integrate them into larger systems.



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.
