Rosreestr: Earth surface deformation monitoring system

2021: Launch of GLONASS Earth Surface Deformation Monitoring System for megaprojects in construction

On March 12, 2021, Rosreestr announced the launch of a surface deformation monitoring system using GLONASS. The technology will help track the speed of annual movement of tectonic plates on which the territory of Russia is located.

The project was implemented together with JSC Roskartography and FSBI Geodesy, Cartography and IPD to ensure the defense and security of the country, as well as for the development of the economy, including the construction complex, infrastructure projects and agriculture.

As explained in Rosreestr, insufficient monitoring of the movement of the earth's surface can lead to serious distortions during cadastral and design and survey work, especially on high-speed highways and other long structures. The establishment of a continuous geodetic monitoring system is also essential for the prevention of tectonic emergencies.

In Russia, there are several types of geodetic networks that use satellites to determine the speeds of motion of the earth's crust. In our country, this figure averages 2-4 cm per year. At the same time, there is a risk of obtaining inaccurate coordinates, since existing points of the geodetic network are displaced due to the movement of the earth's crust.

The so-called geodynamic zoning of modern movements of the earth's crust in Russia includes 12 main regions. So, the area of ​ ​ the Baltic Tectonic Shield is experiencing a rise of up to 6 mm/year. Lifting speeds in the Caucasus reach their maximum value of up to 10 mm/year in the region of Armenia. Movements along the Black Sea coast rarely exceed + 2.5 mm/year.

Monitoring is supposed to be carried out using points of the fundamental astronomical and geodetic network (FAGS), which are equipped with satellite receivers of the geodetic accuracy class and operate in a continuous mode.^[1]
