Goddard's IRAD program is managed under Goddard's Office of Chief Technologist.  Activities are coordinated in collaboration with the Sciences and Exploration Directorate; Applied Engineering and Technology Directorate; Flight Projects Directorate; Wallops Flight Facility; New Opportunites Office; SBIR/STTR program; Goddard Strategic Partnerships Office; and the Export Compliance Office.

IRAD provides"seed funding" to develop concepts, reduce technology risk, and advance human capital and technological capabilities.  The program is highly competitive, opportunity-driven, and 100% strategically aligned with NASA's and GSFC's strategic priorities.  A significant portion of the program is focused on Early Stage Innovations for high-risk, strategically aligned, potential high-payoff technologies that are longer-term or lower TRL.

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.

","benefits":"

More reliable predictions of conjunctions that are many orbit revolutions in the future.
