Performance analysis of BDS B1C/B2a PPP using different models and MGEX products
TL;DR: In this article , the precise point positioning performance of the new BDS signals was evaluated using the observation data of 56 MGEX stations for 30 consecutive days, and the 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.
