Abstract
In a distance control method of relative motion between satellites, by reducing the distance between a companion satellite and a reference satellite through the first position relation, and increasing the distance between a companion satellite and a reference satellite according to the second position relation, the distance between satellites can be kept between the set maximum distance and the minimum distance. In this way, on the one hand, the inter-satellite distance cannot be too large to ensure that the two satellites are within the maximum distance range required by communication or other cooperative relations. At the same time, the inter-satellite distance cannot be too small, and further avoid the collision between the two satellites. The method is capable of tolerating the effect of satellite orbit perturbation, allowing the inter-satellite distance to vary naturally between maximum and minimum distances, and thus saving control fuel consumption.
