Precise Point Positioning for timing
In recent years, many national timing laboratories have installed geodetic Global Positioning System receivers together with their traditional GPS/GLONASS Common View receivers and Two Way Satellite Time and Frequency Transfer equipments. Many of these geodetic receivers operate continuously within the International GNSS Service (IGS), and their data are regularly processed by IGS Analysis Cent...
متن کاملPrecise Point Positioning for Mobile Mapping
The method of precise point positioning (PPP) using un-differenced code and carrier phase observations in combination with measurement corrections is discussed. The implementation of PPP in mobile mapping is addressed. Two approaches are investigated. In the first, measurement corrections optimized for the work area, including atmospheric corrections, are wirelessly received from a local servic...
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 کاملGPS Precise Absolute Positioning via Kalman Filtering
Applied Research Laboratories, The University of Texas at Austin (ARL:UT), under sponsorship of the National Geospatial-Intelligence Agency (NGA), has developed precise positioning software that uses dual frequency GPS carrier phase and pseudorange data to obtain 2-3 centimeter level positioning accuracy for a single static receiver. The paper describes the design of the algorithm, its implemen...
متن کاملPrecise Point Positioning with Partial Ambiguity Fixing
Reliable and rapid ambiguity resolution (AR) is the key to fast precise point positioning (PPP). We propose a modified partial ambiguity resolution (PAR) method, in which an elevation and standard deviation criterion are first used to remove the low-precision ambiguity estimates for AR. Subsequently the success rate and ratio-test are simultaneously used in an iterative process to increase the ...
