The first autonomous rendezvous and docking in the history of the U.S. Space Program was successfully accomplished by Orbital Express (OE) in May of 2007, using the Advanced Video Guidance Sensor (AVGS) as the primary docking sensor. The United States now has a mature and flight proven sensor technology for supporting Crew Exploration Vehicles (CEV) and Commercial Orbital Transportation Services (COTS) Automated Rendezvous and Docking (AR&D). Video-based sensors have been under regular development, testing, and upgrading at Marshall Space Flight Center (MSFC) for almost 20 years. The first sensor flown was the Video Guidance Sensor (VGS) in 1997, followed by the AVGS on the Demonstration of Autonomous Rendezvous Technologies (DART) mission in 2005 [2]. AVGS has a proven pedigree, based on extensive ground testing and flight demonstrations. The AVGS on the Demonstration of Autonomous Rendezvous Technology (DART) mission operated successfully in "spot mode" out to 2 km. The first generation rendezvous and docking sensor, the VGS, was developed and successfully flown on Space Shuttle flights in 1997 and 1998. Parts obsolescence issues prevent the construction of more AVGS units, and the next generation sensor must be updated to support the CEV and COTS programs. The flight proven AR&D sensor is being redesigned to update parts and add additional capabilities for CEV and COTS with the development of the Next Generation AVGS (NGAVGS) at MSFC. The obsolete imager and processor are being replaced with new radiation tolerant parts.
