SATELLITE COLLISION DETECTION AND AVOIDANCE USING STAR TRACKERS Conference Paper uri icon

abstract

  • A novel method of collision detection and avoidance is presented based on on-orbit orbit determination. A star tracker on-board a satellite with known orbit parameters is used to determine the orbit of an unknown object. The orbit determination method is based on multiple line-of-sight measurements only. The object is then tracked to predict the time and location of a potential collision. The effects of measurement error and propagation error are discussed. Multiple orbit types are tested and the results presented, along with an analysis of the required number of observations and time between observations for accurate results.
