Establishment and assessment of a zenith wet delay (ZWD) augmentation model

GPS Solutions, 2021
The zenith wet delay (ZWD) accuracy is one of the most important factors affecting the convergence time and the positioning precision in precise point positioning processing. Taking into account the limitation of the empirical and blind ZWD models, the correlations between the ZWD and temperature and water vapor pressure at each point of the global 1o ×

Zenith Wet Delay Estimation and Radio Source Sky Coverage

Advanced Materials Research, 2013
This paper investigates some approaches to improve the accuracy of parameter estimation in geodetic Very Long Baseline Interferometry (VLBI). By analyzing the radio source Sky Coverage (SC) for each antenna, a new approach, the method of condition number is proposed to find out reasonable time ranges for zenith wet delay (ZWD) estimation.

The Validation of WET Zenith Delay of Ground GPS Stations Based on Jason-2 AMR

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The wet zenith delay(WZD) can be estimated by ground GPS stations as well as satellite altimeter. The Jason-2 altimeter has been an operational satellite, which provides the sea surface height with several centimeters, and have the high accuracy of measuring the WZD using a Microwave Radiometer (AMR).
