THE CONCEPTION OF INTEGRATED SURVEY NETWORKS COMPOSED OF MODULAR NETWORKS AND GPS VECTORS
Tadeusz Gargula · Survey Review · 2009
The main feature of the modular network method is a possibility of quickly establishing the measurement network with concurrent tachymetric measurement of situational details. The network is established on site, without being earlier designed in any way. Sites are usually selected in any place and treated as temporary (lost) points. This paper puts forward a proposal to strengthen the structure of modular networks with GPS measurements. GPS vectors can be adjusted together with the modular network. What is obtained as a result, are the coordinates of tie (connecting) points, which are necessary for the final transformation to the reference coordinate system. Measurement results can be adjusted with the use of multi-group transformation. The method leads to the solution of a system of conditional equations with unknowns. The issue of numerical development may be related to integrated networks considered as 2- or 3-dimensional structures.
