The system G.P.S. (Global Positioning System) has revolutionized in recent years the techniques of surveying.
The continuing evolution of the system, the technological innovation of receivers, new methodologies: VRS (Virtual Reference Station), the entry of GPS survey in the Italian Cadastre (Pregeo 8), have contributed to the growing interest from the technical working in the field surveying in this technology, by bringing this acronym (GPS) in their common phraseology.
But the GPS system is not the only existing satellite constellation, in fact at the end of the 80 former Soviet Union developed the system GLONASS.
In recent years we have witnessed the performance of many initiatives born with the clear intention of spreading the knowledge and proper disclosure of GPS technology (conferences, meetings, courses, events), but very rarely or almost never during these initiatives has been fairly discussed GLONASS (Global Navigation Satellite System).
The lack of information and knowledge has made to date the system GLONASS little known and therefore underestimated.The task of this site is therefore to guide the visitor to a knowledge of the facts and the history of the GLONASS system.
The main source of information is the official website of the GLONASS system, all other information are the result of internet searches with references to the links page.
