In late September, the second generation polar-orbiting meteorological satellite "FY-3" 03 will be launched. Yang Zhongdong, Chief architect of the ground application system of FY-3 said that at present, FY-3A and FY-3B, the new generation polar-orbiting meteorological satellites, were in on-orbit operation, and were in the AM and one in the PM orbit respectively. The 03 satellite is the first operation satellite and will be called FY-3C after launching. It will replace FY-3A in the AM in orbit.
He introduced the 03 satellite has four improvements in remote sensing instruments compared with FY-3A and FY-B.
Firstly, it is installed radio occultation. Secondly, the number of detection channels of microwave thermometer was added from 4 to 13. Thirdly, the number of detection channels of microwave hygrometer was added from 5 to 15. The last, moderate Resolution imaging spectrometer is installed moon observation content.
Yang said the performance indicators of 03 satellite show better results than FY-3A and FY-3B. Currently, the ground application system of 03 satellite has passed the CMA inspection, and is ready for launch. (Sep. 11)
