Improving GNSS Meteorology by Fusing Measurements of Several Colocated Receivers on the Observation Level

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Zenith wet delay (ZWD) estimation is a key component for the global navigation satellite system (GNSS) meteorology. At present, the zenith hydrostatic delay can be computed with sufficient accuracy by means of empirical models, while the ZWD, which is ...

Improved empirical zenith tropospheric wet delay models based on a novel machine learning fusion algorithm

Abstract Zenith tropospheric wet delay (ZWD) plays a vital role in the analysis of space geodetic observations. In recent years, machine learning methods have been increasingly applied to improve the accuracy of ZWD calculations. The most widely used approaches are random forest (RF) and back propagation neural network (BPNN) models, both of ...
