Results of Experimental Studies on the use of PPP Technology for Global Navigation Satellite Systems of Monitoring of Sayano-Shushenskaya HPP

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. Annual measurements from two stations of the satellite monitoring system of the Sayano-Shushenskaya HPP are considered. This data was processed using the absolute PPP method and the relative method in the BERNESE software product. The RMS between the two solutions was 2.0 – 3.5 mm for the horizontal coordinates and 6.3 – 7.5 mm for the height. Using the PPP method, it was established that the annual variation of the earth’s crustal sediments in the area of the HPP due to the effect of atmospheric loads is 31.3 mm, and the annual variation due to the influence of the water reservoir is 9.7 mm. PPP technology can be used to monitor the horizontal position of hydropower structures on a compressible base. Using the PPP method, geodynamic studies of differences in the sediments of the earth’s crust caused by the water reservoir influence at the locations of base stations and monitoring stations can also be performed.
