Relative global positioning system (GPS) navigation is currently used for autonomous rendezvous and docking of two spacecraft as well as formation flying applications. GPS receivers' measurements are used by the navigation subsystem to determine estimates of the current states of the spacecraft. The success of autonomous proximity operations in the presence of an uncertain environment and noisy measurements is highly dependant on the navigation accuracy. This paper presents the comparison of four Kalman filter architectures to be used for relative GPS navigation. A trade study is performed with the advantages and disadvantages of the four different Kalman architectures used for relative GPS navigation presented and compared.
