Introduction to Ranging Principle 1 On June 10, 997, China successfully launched its first geostationary meteorological satellite, the FY-2 (FY-2), and set a spot on the 17th at 105 ° E over the equator . The satellite adopts 3-point ranging orbit determination technology, that is, according to 3 ground stations that are not on the same straight line (central station: Beijing Ranging Master Station, secondary station 1: Guangzhou Ranging Secondary Station / Australian Secondary Station each other
