Abstract
AbstractFormation and attitude control strategies for the CanX-4 and CanX-5 nanosatellite formation flying mission are discussed. An innovative strategy for managing reaction wheel momentum build-up using planned formation control thrusts is presented, and an attitude control method to maximize GPS signal acquisition is reviewed. Fine formation keeping mode, formation reconfiguration mode, and station keeping mode controllers are reviewed. High fidelity simulations with representative control and estimation errors show that the proposed attitude and formation control strategies are effective and meet performance requirements in all cases. It was found that errors in the relative velocity estimates have the largest effect on formation control errors.
