- Abstract
In this paper we, present a leader-follower satellite formation flying navigation and guidance algorithm. First a mathematical model of relative translation and rotation consisting of two spacecrafts is derived. For relative rotation, a backstepper controller is derived, and for relative translation, a velocity sliding surface controller is derived. Both models are shown to be stable according to Lyapunovs stability criteria. Both models have then been coupled together with an algorithm presented in this paper. The idea of the algorithm is to let the follower spacecraft change its attitude relative to the leader spacecraft. Then the relative position is regulated to a reference point in space using thrust in two directions along one body axis. At the end, the spacecraft is regulated back to pointing at the leader spacecraft. Simulations have been performed using Matlab to visualize the results. The results from the simulation shows that both the attitude error and position error converges towards zero.
