Abstract :
In this paper, an earth observation Microsatellite communication system is proposed. The spacecraft will revolve in a sun-synchronous retrograde circular orbit. Therefore, it is equipped with two banks of cameras giving a total of 600 km field of view at 30 meters spatial resolution in three spectral bands, the Red, Green and Near Infra-Red. The communication sub-system is designed to support the mission and the telemetry/telecommand data. The imaging system allows windowing and it is supported by a total storage capacity of 0.5 Gbytes of data, which could be downloaded to a ground station at 8 Mbps within 10 min. The downlink and the uplink, both operate in S band at 8 Mbps in normal operation and 38.4 kbps during commissioning for the downlink and at 9.6 kbps for the uplink. This paper describes the different modules constituting the communication system.
