SEQUENTIAL ANALYSIS OF CONTROL MEASUREMENTS IN TOPOGRAPHIC AND GEODETIC PRODUCTION

When performing topographical surveying, when performing planning, construction - installation and other works, it is necessary to perform control - geodetic measurements of the quality of their execution. Until now, control and geodetic measurements were established for various reasons, which did not have a completely specific scientific and industrial approach. It will be most correct to perform control-geodetic measurements using the method of probabilistic-statistical sequential analysis, the foundations of which were developed by Wald. Sequential analysis has already been used to optimally determine the methods of angular measurements in triangulation, but it should be noted that the calculated number of measurements in triangulation (polygonometry, trilateration, GPS) is known in advance, it is given in the instructions.  When using control-geodetic measurements, their number is unknown in advance, for this purpose, the theory of sequential analysis using Markov random processes was refined.
