Design method of service track providing ontrack service for satellite constellations

Abstract

The invention provides a design method of a service track which provides an ontrack service for integral satellite constellations by using a few track service spacecrafts within limited time. In the design method, by utilizing the characteristic of constellation configuration, one track service spacecraft is arranged on each constellation track surface by taking the track surfaces as units, an elliptical service track which is in coplanar intersection with corresponding tracks of the constellations in a mode of a single intersection point, and the semi-major axis and eccentricity of the single-intersection point elliptical service track and phase difference among target satellites on the corresponding tracks of the constellations meet a certain relation, so that the single track service spacecraft is intersected with different target satellites on the corresponding tracks of the constellations when passing through the intersection points of the tracks every time to perform each ontrack service operation. Based on the constellation target service tasks, the relative speed that the track service spacecrafts are intersected with the target satellites is small and the duration of time windows is long, and the design method has excellent adaptability to different ontrack service tasks.

Description

technical field [0001] The invention relates to a design method of spacecraft orbit, in particular to a service orbit design method for providing on-orbit service for satellite constellations. Background technique [0002] With the development of space technology, how to ensure the long-term normal operation of spacecraft in complex space environments and maximize the on-orbit life of spacecraft has become an urgent problem in the field of aerospace technology. The concept of "on-orbit service" has been proposed as early as the 1960s. With the development of more than 40 years, it has formed an On-orbit service technology including refueling, maintenance and repair, function replacement and upgrade, on-orbit assembly, etc. [0003] At present, foreign on-orbit service targets are mainly based on a single satellite, and the focus is on the demonstration and verification of on-orbit service technology. The orbit design method is the optimal rendezvous orbit design method bas...

AI Technical Summary

Problems solved by technology

However, because the service orbit and the constellation target orbit intersect in different planes, when the orbit service spacecraft approaches the constellation satellite, the relative speed between them is too high, and it is very difficult to perform orbit service
