The launch of 18 satellites in the global coverageconstellation will be completed in 2018 to guarantee basic service for countries along theBelt and Road route. By 2020, 35 Beidou-3 satellites will have been sent into space,providing service to users around the globe. In addition to expanded coverage, theperformance of Beidou-3 will be greatly improved. Its life span can reach 12 years.
Five experimental Beidou global navigation satellites have been launched since 2015,according to Guo Shuren, assistant to the chief engineer of the Beidou-2. Based onexperimental verification, a basic plan for the Beidou-3 satellite system has already beenconfirmed, Guo added. China is striving to complete a PNT (positioning, navigation andtiming) system with the Beidou, in a bid to improve its spatial-temporal informationservices.
