On January 9, 2019, BNU-1 Polar Observation Small Satellite entered the stage of assembly in Shenzhen. By the end of the 12th day, it has completed the comprehensive electrical measurement of wide-band camera and satellite platform; the roof of satellite platform is covered; the installation of camera load and power-on test, and all work is progressing smoothly. At present, the installation of solar wings is under way. Next, the mass characteristic test before satellite vibration, the precision measurement of camera and star sensitivity, as well as large-scale vibration test, thermal and magnetic test will be carried out.
The BNU-1 polar observation small satellite was jointly developed by Beijing Normal University, China Great Wall Industry Group Co., Ltd. and Shenzhen Aerospace Oriental Red Sea Special Satellite Co., Ltd. It is the first remote sensing small satellite for polar observation in China. The experimental load carried by the satellite design can realize complete coverage observation every five days in the north and south poles, obtain high-quality polar remote sensing data, and provide reliable ice information for the ship to ensure safe navigation in the polar region.
The satellite is expected to be launched on June 22, 2019. In addition to priority protection for polar observation missions, observations will also be carried out in the middle and low latitudes. The development of this satellite is a good start for the implementation of the "Three-Pole Scientific Experimental Satellite" project proposed by our university, which is of strategic significance for polar research.
The final assembly tester is installing the sun wing
