Abstract:FY-3 polar orbiting meteorological satellite is China's independent development of a new generation of polar orbit meteorological satellite,It is by far the most complete function, in our country, the most widely used commercial satellite. Guangzhou meteorological satellite ground station FY-3 ground system is FY-3 system engineering is an important part of, South China region for receiving FY-3 satellite cloud,More frequent thunderstorms in Guangzhou, In the light of Guangzhou station FY-3 equipment distribution, We designed a set of lightning protection scheme ,After nearly four years of operation,The lightning protection design is reasonable, applicable, safe, and reliable,Can effectively avoid and lightning defense equipment invasion,For the entire FY-3 system to ensure the safety operation。
