The Advanced Video Guidance Sensor (AVGS) is the continuation and advancement of the Video Guidance Sensor (VGS) Developed by NASA/MSFC in the mid 1990's and flown successfully as an experiment on STS-87 and STS-95 in the late 1990's. The AVGS is designed to be an autonomous docking sensor using the same concept as the VGS, but with updated electronics, increased range, reduced weight and improved dynamic tracking capability. Currently under development as part of NASA's Demonstration of Autonomous Rendezvous Technology (DART) program at Orbital Sciences Corp, the AVGS will be the primary sensor at close in ranges. The AVGS is designed to provide line of sight bearing from greater than one kilometer and provide 6 DOF relative position and attitude data from 300 hundred meters to dock. This paper will provide an overview of the AVGS basic operation, improvements over the original VGS, development challenges, its current status and role in DART mission.
