This paper presents the redeployment and demonstration of the Photogrammetric Video Guidance Sensor (PVGS) as a position and attitude sensor for proximity maneuvers and formation flight of small spacecraft. The original PVGS was developed to use a smartphone as its hardware and an Android application as its software; however, this paper provides a possibility for using a smaller and cheaper single-board computer, Raspberry Pi as new hardware, and for using a Java program run in Linux as its software. We finally achieved the approximate performance compared to the original PVGS. At the current stage, a PID controller was supposed to be used to generate the control command based on the PVGS measurements. The system was demonstrated as controlling the 3-DOF planar motion dynamics of the Resonant Inductive Near-field Generation Systems, RINGS ground unit. The system’s motion control performance was experimentally demonstrated in the tracking maneuvers. The results highlight the capabilities and performance of Raspberry Pi PVGS as a vision-based, real-time position and attitude sensor for motion control.
