| Abstract: | According to existing norms and combined with the actual production practices, this paper firstly tests the compatibility of GNSS control network starting points by using of plane coordinates of four parameters for conversion, and then analyzes the influence of adjustment resuhs caused by the GNSS control network starting points＇ compatibility and distribution with a case. It provides a certain reference on the selection of GNSS control network starting point. |
