ABSTRACT
A new algorithm for determining of the point coordinates and systematic distance errors in geodetic network solution is presented. Geodetic network solution should be understood as a system which consists of reference points, transition points, observations (distances), the systematic errors, and the unknown coordinates of the point to be determined. Transition point indicator definition is based on the reference point indicator definitions developed by the author. With the use of definitions of these point indicators, there is a solution for the sought point and systematic error in 3D geodetic network solution. The direct solution without application of the least squares method is derived. In the proposed solution there is no need to know the initial approximate location of the determined point, nor the coordinates of the transition points. In this article the basic principles of the methods for solving the positioning and systematic error determination problem in geodetic network are presented, and the formulas are given. The numerical example with simulated data confirm the correct performance of the proposed algorithm. The presented method should be further tested with real measurements in many domains of positioning and navigation as well.
