Technical Focus
The primary emphasis is on dynamics and control, with a specialization in
estimation problems and Kalman filtering. Applications of primary interest include
GPS/GNSS-based navigation, GPS/GNSS receivers for new signals or unusual environments,
spacecraft orbit determination, and spacecraft attitude determination &
control. Efforts include the development of novel system designs/concepts, the
corresponding problem models, and the associated numerical estimation algorithms.
Some projects involve flight hardware and experiments or campaigns to collect
remote-sensing data. Other projects are based primarily on analysis and simulation.
Virtually all efforts include significant development of custom-designed numerical
analysis algorithms and software.
