ABSTRACT

To compare and evaluate the performance of different multi-GNSS fractional cycle biases (FCBs) products and precise point positioning (PPP) ambiguity resolution. We compare the stability and positioning performance of the School of Geodesy and Geomatics (SGG) and CNES GPS\Galileo FCBs products. The results show that similar stability and high consistency are observed between the two products, the difference of PPP ambiguity resolution bias between them is in the level of millimetre. And it is found that the epoch-interval of narrow-lane FCBs can be enlarged from 15 min to 30-180 min, to ease the transmission pressure on the transmission link.

摘要

比较和评估不同多 GNSS 分数周期偏差 (FCB) 产品和精确点定位 (PPP) 模糊度分辨率的性能。我们比较了大地测量学院 (SGG) 和 CNES GPS\Galileo FCBs 产品的稳定性和定位性能。结果表明，两种产品具有相似的稳定性和较高的一致性，它们之间的PPP模糊度分辨率偏差差异在毫米级。研究发现，窄车道FCB的历元间隔可以从15分钟扩大到30-180分钟，缓解传输链路的传输压力。
