Detection of erroneous values in the measurement of local geodetic networks

Abstract

For processing the results of local geodetic network (LGN) measurement with possible erroneous values and coordinates:d (slope distances between the points), ω (horizontal angles), z (zenith distances). CDB = [X ,Y]DB (coordinates of the datumpoints), CU0B = [X 0 ,Y 0 ]UB (coordinates of approximately determined points) and detecting the errors it is appropriate to usea technique that will be further demonstrated in a real situation of the trilateration LGN (fig. 1) with a massive contaminationof the simulated errors in the measured elements and numerically determined values.
