Particle filter Simulation and Analysis Enabling Non-Traditional Navigation
Project Introduction
Particle Filters (PF) maintain a large cloud of separate estimates, or particles. PF's are potentially better able to handle significantly non-Gaussian errors, such as occur in conjunction prediction and orbit determination with event-driven disturbances. From among the wide range of possible PFs, we are investigating the approach best suited to NASA's non-traditional navigation challenges.
Incorporate PF into GSFC's Orbit Determination Toolbox (ODTBX). Augment PF with ODTBX' unique ability to partition error sources into subspaces for analysis. Utilize multi-core server to facilitate fast simulation of large particle populations.
More »Anticipated Benefits
Improved navigation performance and robustness for spacecraft perturbed by venting, momentum dumping, and other undetected small forces such as will occur with JWST and the Multi-Purpose Crew Exploration Vehicle.
