Abstract:	The Goddard Space Flight Center Flight Dynamics and Mission Operations Divisions have jointly investigated the feasibility of engineering modular Global Positioning System (GPS) navigation software to support both real- time flight and ground postprocessing configurations. The goals of this effort are to define standard GPS data interfaces and to engineer standard, reusable navigation software components that can be used to build a broad range of GPS navigation support applications. The paper discusses the GPS Modular Software (GMOD) system and operations concepts, major requirements, candidate software architecture, and recommended data interface formats. In addition, ongoing efforts to develop modular software components to support autonomous navigation using GPS are addressed.
