Numerical Research on Satellite Avoidance Strategy

With the increasing number of space debris, space environment becomes more worsening. Space collisions between two objects take place more frequently which leads to more debris in space. The "active" satellites which carry out their routine tasks will face more collision threat. It's important to establish satellite avoidance strategy in order to prevent satellite from collision. Three contents are researched in this paper. First, foreign process of satellite avoidance is studied. Second, factors including orbital maneuver, orbital propagation and computation of collision probability that affect the estimation of satellite avoidance strategy is analyzed. The third, numerical estimation process of satellite avoidance strategy is established which can be used to provide suggestions for department of satellite management.
