Accuracy Improvement of Tropospheric Delay Interpolation in RTK Networks
The effect of troposphere on the signals emitted from global navigation satellite system (GNSS) satellites, appears as an extra delay in the measurement of the signal traveling from the satellite to receiver. This delay depends on the temperature, pressure, humidity as well as the transmitter and receiver antennas location. In GNSS positioning, tropospheric delay effects on accuracy of differen...
متن کاملMitigation of Tropospheric Delay on InSAR Interseismic Displacements
One of the major challenges of Interferometric Synthetic Aperture Radar (InSAR) technique is the existence of tropospheric effect on the results. The tropospheric effect is due to the changes of atmospheric parameters including temperature, pressure, and humidity between the master and slave images. In this research, two different methods based on spatial-temporal filters and calculation of pha...
متن کاملSimplification of Ternary Function using Variable Entered Mapping Technique
This paper describes the steps for minimization of ternary function i.e. three level logic using variable entered mapping technique. Here we applied VEM technique successfully to the ternary function and result is verified using truth table of given ternary equations. We also implemented simplified expression using decoder and ternary gates as well as using ternary multiplexer. It will be more ...
متن کاملInvestigation 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 کاملImproved Mapping of Tropospheric Delays
The authors compare several methods to map the a priori tropospheric delay of global positioning system (GPS) signals from the zenith direction to lower elevations. This is commonly achieved with so-called mapping functions. Dry mapping functions are applied to the hydrostatic delay; wet mapping functions are used to map the zenith wet delay to lower elevation angles. The authors compared the f...
