摘      要：Service accuracy of global navigation satellite system （GNSS） is determined by satellite constellation, sig- nal-in-space （SIS） accuracy and signal transmission errors. The State Council Information Office of the People＇s Repub- lic of China issued China＇s BeiDou Navigation Satellite Sys- tem （BDS） White Paper （***/***） on Jun. 16th 2016, which notes that, BDS takes a three-step development strategy, from domestic service, through Asia-Pacific regional service, to global service, and features mixed constellation of Geostationary Earth Orbit （GEO）, Inclined Geostationary Earth Orbit （IGSO） and Medium Earth Orbit （MEO） satellites.
