Autonomous Onboard Space Navigation in the Absence of GPS (2017-2020)
This research supports the NASA Johnson Space Center to broaden the capabilities of autonomous nonlinear onboard space navigation in the absence of GPS. One of the main goals is the support of the relative navigation system development of the NASA Orion vehicle. This research directly supports our Autonomous Vehicles and our Vision-Based Navigation core research areas.
Refinement and Validation of Radiation Pressure Models for High Area-To-Mass Ratio Space Objects for Improved Characterization, Tracking, and Orbit Prediction (2018-2021)
This joint research collaboration with Dr. Moriba Jah supports the Air Force Office of Scientific Research to investigate how to model high area-to-mass ratio space objects and to develop nonlinear estimation techniques to track them. This research directly supports our Nonlinear Estimation and our Orbit Determination core research areas.
Synthetic Aperture Radar Image Formation and Feedback to Navigation Subsystem in Global Position System Denied and Degraded Environments (2018-2020)
This joint research collaboration with Dr. Ann Chen supports Sandia National Lab in the developing a terrain relative navigation system able to generate and use Synthetic Aperture Radar images in GPS-denied environments. This research directly supports our Vision-Based and Onboard Navigation core research areas.
