Particle filter Simulation and Analysis Enabling Non-Traditional Navigation Project
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.
Anticipated Benefits
More reliable predictions of conjunctions that are many orbit revolutions in the future.
