南极地区BDS-3新频率性能评估

Performance Evaluation of BDS-3 New Frequency in Antarctica Region

针对BDS-3新频率B1C和B2a在南极地区定位性能评估问题,本文基于南极地区CAS1站连续7 d数据,分别进行了BDS-3新频率伪距与精密单点定位实验。实验结果表明,南极地区BDS-3新频率单点定位性能较优,B1C频率和B2a频率伪距单点定位精度可以达到米级,B1C/B2a静态精密单点定位精度可以达到厘米级,仿动态精密单点定位水平精度在厘米级,高程精度在分米级,可为今后研究BDS-3在南极地区的定位性能提供一定的参考。

In response to evaluate the positioning performance of BDS-3 new frequencies B1C and B2a in the Antarctic region,based on the data of CAS1 station in the Antarctic region for 7 consecutive days,this paper carried out BDS-3 new frequency pseudo-range and precise single point positioning experiment respectively.The experimental results show that the new frequency BDS-3 has better positioning performance in the Antarctic region.The positioning accuracy of B1C frequency and B2a frequency pseudo-distance single point can reach the level of meters,the positioning accuracy of B1C/B2a static precise single point can reach the level of centimeters,the horizontal positioning accuracy of imitation dynamic precise single point is in the level of centimeters,and the elevation accuracy is in the decimeter level.It can provide some reference for the future study of the positioning performance of BDS-3 in the Antarctic region.
