Abstract:

With the improvement of BDS system and the modernization of GPS system, GPS+BDS dual system positioning based on RTK technology has become more and more important in engineering applications. Currently, some vendors have integrated the RTK positioning engine in the GPS+BDS receiver module. This article mainly studies the method of realizing the RTK positioning technology with low cost GPS+BDS module, either through the traditional RTK method or the network RTK method. This study designed a receiver based on low cost GPS+BDS receiver module and compared the positioning effect of RTK positioning based on self-designed reference station and network RTK positioning based on Qianxun location network under static scene.In addition, the dynamic scenario in practical engineering applications are simulated. The test results show that even with low cost GPS+BDS receivers, real-time positioning accuracy of centimeters can still be achieved with the RTK positioning method under short-baseline conditions. This technology can be applied in the practical project.

Key words: GPS+BDS, RTK, RTCM, network RTK
