Abstract

Abstract: Nowadays, GPS is the main technology for the establishment of regional high-precision coordinate frame. Since BeiDou Satellite Navigation and Positioning System (BDS) is developed by China independently, it is very important to assess the possibilities to establish a high-precision reference frame using the BDS only. In this paper, a high-precision regional coordinate frame of Changzhou city is established by using BDS data from Changzhou Continuously Operating Reference Stations (CZCORS), where an un difference data processing strategy is adopted. The results are compared with those of GPS. It is found that the difference between them is quite small. The average RMS values in the horizontal and vertical directions are 3.1 and 4.2 mm, respectively. These confirms the potential for BDS to establish the regional reference framework.

Key words: BDS, GPS, CZCORS, regional reference frame, high-precision
