Autonomous Satellite Navigation at the U.S. Naval Research Lab

Autonomous satellite navigation research at the U.S. Naval Research Lab seeks to develop spacecraft that can operate independent from any external navigation systems. This has the potential to reduce the burden on those external systems and improve system reliability when faced with outages in external navigation systems. Similar to a pilot's use of dead reckoning, known landmark navigation uses distinctive features whose location is know a priori for navigation relative to a celestial body's surface. This seminar includes an overview of the system, as well as a survey of recent results from sensitivity and observability analyses.
Evan Ward received his B.S. in Aerospace Engineering from Penn State and his M.S. in Computer Science from Johns Hopkins. He currently works in the Astrodynamics and Navigation Section at the U.S. Naval Research Lab in Washington, DC. His interests include autonomous navigation, geolocation, and orbit determination. He currently leads development of the Orbit Covariance Estimation and ANalysis (OCEAN) software and serves on the Project Management Committee for the Orekit open source space flight dynamics library.
