Impact of Multi-GNSS on Positioning Accuracy and Multipath Errors inn High-Precision Single-Epoch Solutions - A Case Study in Ningbo China

摘要

Real-Time Kinematic (RTK) Global Positioning System (GPS) carrier phase-based precise positioning has been widely using in geodesy and surveying applications, and other high accuracy positioning and navigation applications in the last two decades. More Global Navigation Satellite Systems (GNSS) are being developed and it is usually expected that combining GNSS will have a positive impact on positioning accuracy. This paper describes a case study carried out at Ningbo in China on the impact of mu
