Comparative Research on Early Warning Determination Methods of Spacecraft Collision

Abstract

With the development of space science, more and more spacecraft have entered into the space, and the operating environment of spacecraft in space has become more complex. Various signs show that the future space field will face congestion, collision and other safety problems, so the collision warning in space is becoming more and more important. It is the primary guarantee for the spacecraft to carry out its mission in space in the future to obtain the early warning information and complete the avoidance within the early time to ensure the environmental safety. In this paper, based on the perspective of collision warning and determination methods, two kinds of warning and determination methods are introduced, including BOX region method and probability method. In addition, by comparing the warning efficiency of these two methods, the results show that, under the same constraint, the probability method is more accurate and saves more space resources than the BOX region method. Considering that the spacecraft is limited in fuel and other resources when working in orbit, it is more scientific to adopt to avoid unnecessary maneuver and waste of resources.
