Geophysical processes and biosphere: article

Аnnotation: On the territory of the Institute of Physiology of Natural Adaptations of the Ural Branch RAS (Arkhangelsk region) the Geophysical Center RAS created a permanent GNSS-station as part of the «Klimovskaya» integrated geomagnetic observatory. The article provides a detailed description of the stages of laying and equipping the GNSS-complex, describes technological and design solutions, and presents the first results of assessing the quality of the recorded data. After laying the site to study the stability of the geodetic center, test GNSS-measurements were organized using a choke-ring antenna. To process the measurement results, specialized services were used that implement var-ious strategies for processing static GNSS-measurements. The study of time series of increments of coordinates obtained by different services makes it possible to additionally control the quality of GNSS-measurements. Observation graphs were built for all three services selected, from which it can be seen that the smallest RMS values and measurement scatter were obtained by the AUSPOS and CSRS-PPP services. A comparison was made of the average annual speed of the GNSS station of the geomagnetic observatory «Klimovskaya» with the points of the GNSS «Svetloe» of the international network IGS. The velocities of horizontal movements are close to each other in numerical values and directions. Vertical movements often have local and regional causes.
