Оптимизация условий применения системы ГСК-2011 в Дальневосточном регионе

Abstract

ITRFs and ITRF like reference frames have a drawback that limits or makes its wide use difficult while surveying in the Russian Federation. These are significant velocities of changing geodetic stations’ coordinates throughout the entire territory. It leads to necessity of reducing reference geodetic stations and survey points positions from reference epoch to observation ones and vice versa. To avoid this necessity for the most of surveys in the Russian Federation territory, a transformation model [1] of relative behaviour of GSK-2011 and ITRF-2014 reference frames was created. Unfortunately, the model does not work properly in the Far East. That is why in this paper a new, regional transformation model that represent relative behaviour of GSK-2011 and ITRF-2014 reference frames in the territory was described. As it was shown in the paper, the result is equivalent to setting a new, auxiliary version of GSK-2011 reference frame in the Far East territory – GSK-2011-FE, that has no drawbacks of ITRF-like systems. Both frames coincide with each other at the reference epoch t0 and relate by a transformation of angular motion at an epoch t.
