INVESTIGATION OF THE ACCURACY OF THE TRANSMISSION OF AXES TO THE MOUNTING HORIZON BY THE GPS METHOD
Studies of the accuracy of the transmission of axes from the initial to the mounting horizon were carried out using GPS receivers from Topcon (Japan) and Trimble (USA). As a result of geometric modeling of the internal grid on the initial and mounting horizons, it was found that the used GPS devices provide the declared passport accuracy and can be effectively used in the construction of high-rise buildings when transferring points to the mounting horizons in the fast static mode. At the same time, the device of through holes in the interfloor ceilings is excluded. In addition, the transfer of axes to mounting horizons in the fast static mode reduces the measurement time by more than two times compared to the static mode, the use of which is regulated by regulatory documents. At short distances between the base and bodypack, the fast static measurement time can be reduced to 10 minutes.
