Applications of GPS During Spacecraft Rendezvous and Docking

摘要

This article summarizes basic requirements and processes associated withspacecraft rendezvous and docking as well as the composition of the U.S. global positioning system (GPS), the principles of positioning, precision, and difference principles, after which it sets out two types of relative motion equation forms. Making use of a combination of motion equation solutions, pure GPS, and difference GPS, it is possible to complete the entire guidance process of tracking spacecraft approaching target spacecraft. Moreover, it is possible to economize on such equipment as enormous ground telemetry and remote control, radars on board satellites, and so on, reducing sources of error. Simulation calculations verify that this design concept is feasible and accurate.
