Impact of a priori zenith hydrostatic delay errors on GPS estimates of station heights and zenith total delays

[1] Corrections to zenith atmospheric delays (including hydrostatic components) are estimated in geodetic analyses using partial derivatives that relate wet delays to the phase observations. At low-elevation angles, partial derivatives of the hydrostatic and wet delays are sufficiently different as to cause errors in the estimates of station heights and zenith total delays unless accurate surfa...

Tropospheric Zenith Delay Prediction Accuracy for Airborne GPS High-Precision Positioning

When traversing the earth’s neutral atmosphere, GPS radio signals are affected significantly by the variability of its refractive index, which causes primarily a delay, usually referred to in the literature as the tropospheric delay. An inaccurate modeling of this delay results in degradation of position estimates, affecting mainly the height component. The tropospheric delay is commonly divide...

Impact of high-resolution data assimilation of GPS zenith delay on Mediterranean heavy rainfall forecasting

Impact of GPS (Global Positioning System) data assimilation is assessed here using a high-resolution numerical weather prediction system at 2.5 km horizontal resolution. The Zenithal Tropospheric Delay (ZTD) GPS data from mesoscale networks are assimilated with the 3DVAR AROME data assimilation scheme. Data from more than 280 stations over the model domain have been assimilated during 15-day lo...

Impact of stochastic modelling on GPS height and zenith wet delay estimation

Most stochastic modelling techniques assume the physical correlations among the raw observations to be negligible when forming the variancecovariance matrix of the GPS observations. Such an assumption may, however, lead to significantly biased solutions. The Minimum Norm Quadratic Unbiased Estimation (MINQUE) method is an iterative technique that can be used to estimate spatial correlation amon...
