Performance Evaluation of BDS-3 New Frequency in Antarctica Region
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 re-gion.
