Real-time positioning accuracy testing for domestic Beidou platform in Huizhou City
The Huizhou continuous operational reference system(HZCORS)completed the upgrade and transformation to the domestic Beidou system in 2022,making the receiver in the base station now fully support Beidou-3 data.The new domestic Beidou platform(abbreviated as new platform)has the ability to process Beidou-3 data and is compatible with data from other satellite systems.It also supports real-time broadcasting of national elevation benchmarks in 1985(referred to as 85 elevation).As an important support for the modern surveying and mapping reference system in Huizhou City,the testing of the new platform before its launch is particularly important.The test results show that:①The real-time positioning accuracy of the new platform in terms of plane and elevation is improved.②The elevation results obtained by the new platform using the quasi-geoid models of Huizhou City and Guangdong Province fit well.③The average time availability of the new platform is 96.48%,which is better than the regulatory index of 95%.
