Monitoring Station Design of Russian Global Satellite Navigation System GLONASS,

Abstract

This article illucidates the technical standards and utilization ranges associated with the GPS and Glonass combined monitoring stations at Moscow and Neustrelitz. It describes in concrete terms GPS/Glonass combined receivers which Russia is in the midst of studying as well as the future utilization prospects for them in the systems in question. The next generation of receivers will be able to measure carrier wave phases making use of new speeds once each second. In conjunction with this, they will be capable of tracking 16 satellites at the same time. As far as monitoring satellite navigation systems is concerned, it is carrying out observations of connected devices with regard to slant range (illegible) related parameters, monitoring various types of error sources--for example, ephereris and almanac data, star rise time graduation and GPS and Glonass system time graduation errors as well as SGS-85 and WGS-84 coordinate system errors. It illucidates a number of differences between GPS and Glonass. It makes a preliminary comparison of the usability of Moscow and Neustrelitz satellites in order to facilitate--on the foundation of long term research--finding the mutual relationships between error sources and geography. For this reason, the conclusions obtained are capable of providing German and European users additional considerations for future development. It is figured to construct appropriate communication links between Moscow and Neustrelitz in order to facilitate exchanging navigation and positioning data. Making use of this equipment, it is also possible to produce DGPS and DGlonass difference correction values. The purpose is--within a range of 50km of a reference station--to make difference positioning accuracies reach levels of 1.5-2 meters horizontal and 2.0-2.5 meters vertical (RMS).
