Abstract
Today, most precise GNSS products, including orbits and clocks, are provided by the International GNSS Service (IGS) and its Analysis Centers (ACs). Each AC provides its products to the AC Coordinator (ACC) for combination. ACs develop their own software packages by implementing different strategies, which as a result improving the robustness of the combined products. Following the IGS AC strategy and to fulfill the requests of satellite missions in China, we set up the GNSS Analysis Center at Shanghai Astronomical Observatory (SHAO). Currently our GNSS routine analysis includes: Global GPS+GLONASS data processing, GLOBAL+CMONOC GPS data processing. In the first routine, we use ~110 global stations, of which ~50 have GLONASS observations, to derive the integrated and consistent GNSS products. In the second routine, we combine the IGS network used the first routine and the Crustal Movement Observation Network of China (CMONOC) network, GPS only solution is performed using ~300 stations. This paper introduces the details of the Analysis Center and presents the latest results.
