Session
Technical Session IX: New Mission or Bus Concepts II
Abstract
With the development of Micro-lNano-technology, Micro-lNano-satellite are paid great attention and developed rapidly. Tsinghua Space Research Center( TSRC) has planed to develop their Microsatellite and Nanosatellite with the cooperation of Surrey Space Center (SSC). The Tsinghua-l Microsatellite is new generation 3-axis stabile Microsatellite in 50 Kg. It is used as technical demonstration of Microsatellite constellation for globe disaster forecast net. The main Payloads include Multi-Spectral Earth Image System (MEIS) which have a 50 meters ground resolution and the cameras will be mounted 15 degrees off Z-axis of the satellite to meet the 400 kilometre ground swath requirement, Date Transmit Experiment payload which is used to survey the radio frequencies interference and GPS receiver. The THNS-l is a Nanosatellite in 5Kg. One micro magnetometer, three micro 2-d sun sensor, a micro GPS receiver and MIMU is employed to determine the attitude of Nanosatellite. A small gravity-gradient boom is used as basic stabilization of satellite. The main payload is a micro Multi-Spectral Earth Imaging system (MEIS). Three on chip CMOS CCD Cameras providing 250 meter ground sampling in 3 spectral bands with an 75 kIn field of view capable of providing detailed information on Earth resources, land use and environmental haze pollution and etc. The other Micro-Mechanical-Electric-system (MEMS) devices are as experimental payloads also.
