Popis: Japan Aerospace Exploration Agency (JAXA) is planning the next generation magnetosphere observation mission called 'SCOPE' (cross-Scale Coupling in Plasma universE). SCOPE aims at observing the Earth's magnetotail with five satellites flying in formation to fully resolve the temporary and spatial distribution of the magnetospheric phenomena in the near future. For this observation, the clock synchronization and relative distance measurement between the spacecrafts are essential. This paper describes introduced onboard relative ranging and clock synchronization systems and a robust and efficient approach for relative navigation and parameter estimation of spacecraft flying in formation in general in the main topics. In the main focuses, the approach uses measurements from the optical data that provides a line of sight vector from the master spacecraft to the secondary satellite. State estimation for formation flying is achieved through an optimal observer design. Also, because the rotational and translational motions are coupled through the observation vectors, three approaches are suggested to separate both signals just for stability analysis. Simulation results indicate that the combined sensor/estimator approach provides accurate relative position estimate.
