GIS Based Advanced Positioning Technique for Mobile GPS

GPS/GIS for Mobile Equipment Management

Global Positioning System (GPS) has been widely used for precise positioning and navigation and it has also been increasingly used as a data source for Geographic Information System (GIS). This paper describes the concepts of integrating GPS, GIS and wireless communication for the development of a mobile equipment management system. Such a system could result in considerable operational cost sa...

A Gsm Signals Based Positioning Technique for Mobile Applications

New Technique for Proposing Network's Topology using GPS and GIS

The problem of proposed topology for network comes when using Prim’s algorithm with default distance (unrealistic distances) between network’s nodes and don’t care about the lakes, high hills, buildings, etc. This problem will cause incorrect estimations for cost (budget) of requirements like the media (optic fibre) and the number or type of Access-points, regenerator, Optic Amplifier, etc. Thi...

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 ...

RTK-GPS Positioning in Japan by GPS-Based Control Stations via DMCA Mobile Radio Communication System

RTK-GPS is a real time positioning system of the accuracy of one cm order with carrier phase measurement. Many applications are now under examination in Japan. The most indispensable for the positioning procedure are carrier phase data from reference stations. There is at present a mobile radio communication system operating in Japan, called DMCA (Digital Multi-channel Access) system. It can be...
