Romanyshyn I. The development of the technology of the optimal modelling of the GPS networks

An object is the Ukrainian permanent GPS network; a purpose is the development of theoretical bases and praktical recommendation for optimal project of the permanent network in Ukraine and its accuracy estimation and effectivety for aplaing in real-time relativy to the permanent stations; methods - the theoretical analysis of the geodetic networks optimal prejecting, analytical and experimental; scientific novelty - the method, criteria and algoritms for densitication of permanent GPS network in Ukraine were developed, the relation between mean square error of vector lenght and IGDOP, vector lenght, period of measurement was found; results - densification project for the GPS permanent station in Ukraine and nomograms for mean square error determination of vector lenght was found; recomended for by the Scientific research institute of geodesy and cartography, the enterprises of a geodetic structure, in educational process.
