A new technique of the multi-targets management in small satellites system

Under the operating mode of a small satellites system which uses multi-satellites or multi-constellations, more satellites exist at the same time in the view area of one TTC (telemetry tracking and command) station than in traditional systems. Obviously, it is unable to manage them by traditional methods. This paper proposes a new technique, which combines SDMA (space-division multiple access) with spread spectrum CDMA (code-division multiple access). Multi-beamforming is available by parallel data processing and one small satellite is tracked by one beam. Finally, simulation results of digital beamforming are provided
