July 4, 2017 • 137 Views

Workshop 2017 - Shengfeng Gu - The computational efficiency becomes critical issue due to the increasing number of satellites and stations in real-time GNSS applications. In this contribution, we overcome this problem from the aspects of both dense linear algebra algorithms and GNSS data processing. Then, the processing efficiency is further validated in multi-GNSS (GPS/BDS/Galileo) satellite clock estimation with over 80 globally distributed stations. The results suggest that, based on our new algorithm, it takes only 0.50 s and 0.31 s for multi-GNSS clock estimation per epoch for float and fixed clock solution, respectively without loss of accuracy.
