Performance analysis of BDS B1C/B2a PPP using different models and MGEX products
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.
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.
