Engineering Test Satellite-VII (ETS-VII) is a test satellite to perform in-orbit demonstration of autonomous rendezvous docking (RVD) technology, which will be necessary for advanced space activities in the early 21st century. ETS-VII successfully performed the autonomous RVD by unmanned space vehicle for the first time in the world. For an unmanned space vehicle to perform rendezvous to a manned spacecraft, safe approach is needed. So we paid special attention to designing safe approach trajectory. There are other important points for approach trajectory design, for instance, coordination with guidance and control accuracy, performance of navigation sensors, and operability, etc. In this paper, we introduce the points, and show the result of ETS-VII RVD trajectory design.

ETS–VII is a test satellite to perform in-orbit demonstration of autonomous rendezvous docking (RVD) technology, which will be necessary for advanced space activities in the early 21st century. ETS–VII performed three RVD experiment flights, and verified all technical items. ETS–VII demonstrated first autonomous RVD between unmanned vehicles, and remote piloted rendezvous flight position accuracy at docking was about 1cm, and acceleration was less than 1.5mG (low impact docking). In the second RVD experiment flight, ETS–VII detected attitude anomaly and executed disable abort for safety insurance. We present the results and evaluation of three RVD experiment flights in this paper.

ETS-VII is a test satellite to perform in-orbit demonstration of rendezvous docking (RVD) technology, which will be necessary for advanced space activities in the early 21^st century. ETS-VII successfully performed autonomous RVD in the first experiment flight. But in the second experiment flight, seberal times of Z-thruster misfiring occurred and they prevented for ETS-VII to accomplish docking for three weeks. To verify all technical items, the third experiment flight was replanned on condition that firing Z-thrusters should be minimized. And we modified on-board software to continue approach in case that Z-thrusters misfiring occur. ETS-VII succeeded in the third experiment as the result of these countermeasures. We present replanning of the third experiment flight and its result in this paper.
