And the data of RTCM32 format didn’t, which make the observation data such as pseudorange and carrier phase have no receiver offset. Then we will have a problem when we used these posed with RTCM27 format data and RTCM32 format data, and we couldn’t processing the baseline using the double difference mode. Therefore, we need to realize the algorithm of eliminating receiver offset in the observation data, and integrated this algorithm into our CORS software. After that we can process the mixed observation data of RTCM27 format and RTCM32 format. Based on a lot of analysis parison of RTCM27 format data and RTCM32 format data, finding the differences, we test a variety of algorithms to eliminate the receiver clock error using the C++ programming language. Finally, we find a best one. Thereby expand the scope of application of our software engineering in subsequent applications and supports more board data formats.
