Positioning Accuracy Analysis of GPS/BDS/GLONASS Network RTK Based on DREAMNET
With BDS being continually providing service in the Asia-Pacific Region, GLONASS being fully operational with 24 satellites in orbit again and GPS modernization, multi-GNSS network RTK will become the development trend of network RTK in the future. The data of multi-GNSS will be process by data rese...

With BDS being continually providing service in the Asia-Pacific Region, GLONASS being fully operational with 24 satellites in orbit again and GPS modernization, multi-GNSS network RTK will become the development trend of network RTK in the future. The data of multi-GNSS will be process by data reserving, editing and managing system of network RTK (DREAMNET), which developed independently by this research group, to analyze and compare the positioning accuracy between different combinations of global navigation satellite system. According to the experiment, the positioning accuracy of GPS/BDS/GLONASS network RTK and GPS/BDS network RTK is highest, GPS and BDS only second.
