| Popis: | STU-2A, developed by Shanghai Engineering Center for Microsatellites, to validate orbit maneuver technology, is equipped with 3 reaction wheels and the NanoSpace-developed nano-propulsion. The former is used to stabilize and maneuver the attitude of STU-2A before orbit maneuver while the latter is employed for orbit maneuver and satellite stabilization in the process. These actuators ensure CubeSats the capabilities to demonstrate some novel and important technologies, such as space rendezvous. A 4-nozzle nano-propulsion, developed in Sweden, is employed to control the orbit and the attitude of STU-2A simultaneously. Several velocity increments with proper time intervals would be implemented first to adjust the separation distance between STU-2A and STU-2B from the initial relative situation to a proper one, and to ensure the two satellites the same orbital period and near-zero eccentricity. Another velocity increment would result in a kind of formation flying of which STU-2A would cycle to some point and overtake STU-2B along its geocentric orbit. During the process of orbit maneuvers, a thruster-based Bang-Bang attitude control scheme is adopted to guarantee the orbit maneuver executed perfectly. Simulation results indicate that the designed orbit maneuver scheme is feasible and the coupling control law works well with an above 95% effectiveness of orbit maneuver. |
