A Refined Spatiotemporal ZTD Model of the Chinese Region Based on ERA and GNSS Data

A Refined Spatiotemporal ZTD Model of the Chinese Region Based on ERA and GNSS Data

Empirical tropospheric models can improve the performance of GNSS precise point positioning (PPP) by providing a priori zenith tropospheric delay (ZTD) information. However, existing models experience insufficient ZTD profile refinement, inadequate correction for systematic bias between the ZTD used...
