STATION-KEEPING STRATEGIES FOR SATELLITE CONSTELLATION

This paper firstly introduces the concepts on control box and control reference for absolute and relative station-keeping, how to determine the control reference, and the uniform control flow for different station-keeping strategies. And then, studies the different station-keeping control-laws for Walker constellation, including different orbital regions. The demonstration experiments concerning different station-keeping strategies are carried out with initial orbit element errors and control tolerance based on Constellation Station Keeping Kit (CSKK), which is recently designed and developed at BACC for satellite constellation operation demonstration.
