Autonomous rendezvous and docking has become more prominent in the wake of the DART mission. In support of AR&D, NASA and companies such as ours have been developing sensors to measure distance, bearing and pose to target spacecraft. We are developing a suite of such sensors. The sensors include the Advanced Video Guidance Sensor (AVGS), the ULTOR video processor, and the Wide Angle Lidar for Direction and Distance (WALDD). AVGS is a laser-based video sensor that images retro-reflecting targets and extracts six-degree-of-freedom information. WALDD is a staring lidar system that provides range and bearing information using retro-reflecting targets. ULTOR is a video processor that can extract six-degree-of-freedom information from spacecraft that lack special targets. We will give an overview of the three sensors, their development, and their capabilities.
