Abstract

To assess the precise point positioning performance of the new BDS signals, the observation data of 56 MGEX stations for 30 consecutive days were used to carry out dual-frequency PPP experiments. The positioning results showed that the best positioning performance could be achieved with CODE precise products, followed by IAC, GFZ, and WHU products, with SHA products performing the worst. For Ionosphere-free and undifferenced and uncombined models, the performance of the two was comparable. In addition, our study indicated that station location and time were not the main factors affecting the performance of BDS-3 PPP.

使用不同型号和MGEX产品的BDS B1C/B2a PPP性能分析

为了评估新BDS信号的精确点定位性能，使用56个MGEX站连续30天的观测数据进行了双频PPP实验。定位结果表明，CODE精密产品的定位性能最好，其次是IAC、GFZ和WHU产品，SHA产品的定位效果最差。对于无电离层、无差异和无组合的模型，两者的性能相当。此外，我们的研究表明，站点位置和时间不是影响BDS-3 PPP性能的主要因素。

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
