Abstract
Abstract : The United States Navy is developing the space-based Joint Milli-Arcsecond Pathfinder Survey mission (JMAPS) mission to support current and future needs for high accuracy star positions. The primary objective of the JMAPS mission is to generate a star catalog that is 15 times more accurate and 100 times denser than existing bright star catalogs. JMAPS will not only provide required star positions needed by high-accuracy, space-based orientation/attitude users, but JMAPS will also pathfind, mature, and risk-reduce technology for the next generation of high accuracy attitude determination systems. In addition, the JMAPS sensor, optimized to make very high precision measurements of star positions (astrometry), is ideally suited to improve position measurements of satellites and support formation flying applications. We will discuss the status of the JMAPS mission, including the current mission baseline, leading up to a CY 2013 launch.
