Abstract

Abstract: An algorithm of satellite formation flying control in the Low-Earth Orbit using the aerodynamic force is considered. A simple model of the aerodynamic force that takes into account the lift component of the force is proposed. It allows us to calculate the satellite attitude relative to the incoming flow that provides the required aerodynamic force. For the given model parameters the acceptable control region is obtained. The relative motion control algorithm based on the Linear-Quadratic Regulator is considered. The technique for the algorithm parameters determination is suggested. Numerical study of the controlled motion is carried out. The simulation takes into account the second harmonic of the Earth gravitational field and the inaccuracy of the atmospheric density model. Highlights: An algorithm of formation flying control using differential lift and drag is studied. At given parameters of the force model the acceptable control region is obtained. An algorithm parameters adjustment technique is proposed. A numerical study taking into account disturbances and uncertainties is carried out.
