Mathematical Algorithms for Two-Dimensional Positioning Based on GPS Pseudorange Technique

Recently, one has realized that the threedimensional positioning technique used in GPS can be effectively applied to the modern two-dimensional positioning. Such a technique might has applied to the twodimensional positioning in fields of the mobile communication, eLORAN and the GPS jamming/ electronic warfare system. In the paper, we have studied on algorithms for two-dimensional positioning b...

GPS Based Map Matching in the Pseudorange Measurement Domain

Accurate vehicle location is important for various Intelligent Transportation System (ITS) applications such as route guidance and collaborative driving. The Global Positioning System (GPS) has become popular for locating vehicles for many ITS applications due to the 24hour, all weather and free-of-charge availability. Although GPS-based vehicle navigation systems are accurate in open sky condi...

Development and Positioning Accuracy Assessment of Single-Frequency Precise Point Positioning Algorithms by Combining GPS Code-Pseudorange Measurements with Real-Time SSR Corrections

We have developed a suite of real-time precise point positioning programs to process GPS pseudorange observables, and validated their performance through static and kinematic positioning tests. To correct inaccurate broadcast orbits and clocks, and account for signal delays occurring from the ionosphere and troposphere, we applied State Space Representation (SSR) error corrections provided by t...

Stochastic Modelling for Network-Based GPS Positioning

Over the past few years the concept of network-based positioning has been developed in support of longer baseline processing compared with 'traditional' single reference station positioning. In fact network-based positioning enables the generation of so-called ‘virtual measurements’ which can significantly improve positioning results. Even though the virtual measurements are generated from the ...
