Paper Abstract

As NASA develops the new space explorations systems required for the Crew Exploration Vehicle (CEV) also known as ORION, there is a growing need for hardware and algorithms to support Automated Rendezvous and Docking (AR&D) technology for both manned and unmanned flights. A new definition of space hardware is also emerging based on reconfigurable computing. Goddard Space Flight Center (GSFC) has developed a high processing bandwidth hardware platform based on the latest Xilinx Field Programmable Gate Array (FPGA) technology. This platform, called SpaceCube, incorporates the processing power of immersed PowerPC core technology with an extremely flexible I/O capability. The result is an adaptable, reconfigurable computing platform well suited for hosting computationally intensive AR&D algorithms. Advanced Optical Systems, Inc. (AOS) has developed several electro-optical sensor systems for both NASA and the Department of Defense. ULTOR® is one such sensor technology, developed for Automatic Target Recognition (ATR) in missile guidance systems. AOS has applied ULTOR® to target position and attitude measurements in space, commonly referred to as pose estimation. Under GSFC funding, AOS has successfully integrated ULTOR® into the SpaceCube platform. GSFC plans to demonstrate on-station pose estimation using the integrated ULTOR® SpaceCube system on the next shuttle mission to the service the Hubble Space Telescope.
