Technical Session I: Existing Missions
Abstract
The 50kg 3-axis stable Tsinghua-1 microsatellite, the first Chinese university Microsatellite will be launched in Russia by COSMOS rocket before June of 2000. This paper is planning to report the initial mission status of Tsinghua-1 microsatellite. Tsinghua-1 Microsatellite, which is developed by Tsinghua Space Center (TSC) and Surrey Space Center (SSC), is new generational 3-axis stable Microsatellite in 50 Kg region. 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 40 meters ground resolution and the cameras will be mounted 19 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 for orbit determining . This paper will describe the Tsinghua-1’s design in detail,. Specially for the 3-axis stable controlling technology , the image payload and it’s targeting technology . After it be launched, the Initial Mission Status, such as initial attitude capture, 3-axis precision control of the satellite platform and the initial images form image payloads will be published in this paper firstly.
