Estimation of Horizontal and Vertical Components for Positioning Standard Deviation in Absolute Gps Positioning
Precise Point Positioning (PPP) greatly improves the precision of absolute GPS positioning by using the international GPS services (IGSs) orbit and satellite clock error products with positioning precision reaching the 1cm level [1-3]. At present, this technique has been widely applied in many engineering fields, such as mining engineering, high precise navy engineering surveying, lane surveyin...
متن کاملUsing Handheld GPS Receivers for Precise Positioning
In general handheld GPS receivers are used for absolute positioning or for relative positioning using DGPS-services or WAAS/EGNOS signals. The positioning is realized using code pseudo-ranges. Moreover it is well known that some of the handheld receivers use phase-smoothed code for positioning. This means that the phase signal is available and may be used for Precise Differential GPS (PDGPS) po...
متن کاملPrecise GPS Positioning: Prospects and Challenges
Carrier phase-based GPS positioning is now an indispensable tool for a wide range of precise applications in navigation, surveying and geodesy. To address such a variety of applications, many implementations of precise GPS techniques have been developed. Almost all techniques involve 'relative' positioning, in which one GPS receiver/antenna's coordinates are determined with the aid of measureme...
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 کاملCombined GPS/GLONASS Precise Point Positioning with Fixed GPS Ambiguities
Precise point positioning (PPP) technology is mostly implemented with an ambiguity-float solution. Its performance may be further improved by performing ambiguity-fixed resolution. Currently, the PPP integer ambiguity resolutions (IARs) are mainly based on GPS-only measurements. The integration of GPS and GLONASS can speed up the convergence and increase the accuracy of float ambiguity estimate...
