Abstract
Engineering Test Satellite-VII (ETS-VII) successfully performed the first autonomous Rendezvous Docking (RVD) flight using Rendezvous Laser Radar (RVR) in the world. ETS-VII is a test satellite to perform in-orbit demonstration of the autonomous rendezvous docking (RVD) technology. RVR navigation is used primarily in a final approach phase (from 500m to 2m from target satellite). In this paper, we introduce ETS-VII RVR design and evaluation results of its in-orbit performance. In-orbit performance is evaluated in comparison with another navigation sensors such as Proximity Sensor (PXS). Measurement accuracy of RVR is better than its requirement. And it is shown that Laser Radar is useful for rendezvous navigation sensor.
