Investigation of MODIS mission capability in tropospheric delay estimation for precise point positioning
Tropospheric delay is always considered as one of the factors limiting the accuracy of GPS. In this paper, the three-dimensional ray tracing technique is proposed to calculate the tropospheric delay. The ability of the MODIS mission to calculate the tropospheric delay is also examined. For this purpose, an area in central Europe was selected and a MODIS acquisition on 2008/08/01 was studied. In...
متن کاملEstimating the Residual Tropospheric Delay for Airborne Differential GPS Positioning
In post-processing dual frequency GPS carrier phase data, the residual tropospheric delay can easily be the largest remaining error source. This error can contribute a bias in height of several centimetres even if simultaneously recorded meteorological data are used. This shortcoming is primarily due to the poor representation of the water vapour profile in the tropospheric delay models. In add...
متن کاملAdaptive Tropospheric Delay Modelling in GPS/INS/Pseudolite Integration for Airborne Surveying
Integrated GPS/INS systems have been used for geo-referencing airborne surveying and mapping platforms. However, due to the limited constellation of GPS satellites and their geometric distribution, the accuracy of such integrated systems cannot meet the requirements of precise airborne surveying. This problem can be addressed by including additional GPS-like ranging signals transmitted from the...
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 کاملMitigating Residual Tropospheric Delay to Improve User’s Network-Based Positioning
Existing apriori tropospheric models are not sufficiently accurate to remove tropospheric delay from GPS observations. Remaining effects of residual tropospheric delay need to be estimated to ensure high accuracy and reliability of GPS positioning. Other researchers have shown that implementations of network-based positioning techniques can adequately model the residual tropospheric delay as we...
