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...
متن کاملImpact 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...
متن کاملImpact 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...
متن کاملEstimation of Tropospheric Zenith Delay and Gradients
We have analyzed data from an experiment over the Madrid (Spain) area obtained from 5 GPS receivers and 3 Water Vapor Radiometers (WVR), in order to compare their retrievals of Tropospheric Slant Delays. For this purpose we have tted a simple gradient model to both types of data, using a Kalman lter to account for the temporal variability of the zenith and gradient parameters. We show that the ...
متن کاملDetermination of Zenith Tropospheric Delay and Precipitable Water Vapor Using Gps Technology
In order to be able to be process GPS data, the GPS signal it has to pass the entire terrestrial atmosphere – both neutral atmosphere and ionosphere – which may cause an alteration of the GPS receiver to perform, resulting in large errors in the final position estimate. The dual frequency GPS receivers are affected by the influence of the atmosphere, especially by the troposphere. To estimate t...
