Technical Session IIB: Advanced Operations Concept Systems
Abstract
Using the existing commercial mobile communication system (MCS) for reducing the operation cost of SmallSat has been studied. Through comparing the characteristics of several MCS's, a low-cost approach based on Inmarsat is presented. The system architecture for data relay between the lowearth orbiting Small (scientific) satellites and Inmarsat and its possibility for implementation are detailed. The involved technologies and potential problems, such as Doppler shift compensation, antenna tracking etc., are discussed and some considerations are given. A new concept-TT&C paging is presented for the cost-saving operation of SmallSat. The study shows that the proposed system is available for low and medium orbit SmallSat and the achievable data rate is 64kb/s. Without building Specific ground stations, the presented way can reduce the operation cost.
