Abstract

The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy (IAG). IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.

The Hurbanovo gravimetric observatory in southern Slovakia was established in 2019 as a part of the integrated station HUVO (GNSS permanent station and seismic station). HUVO is located on a ground floor in a small building in the vicinity of the Hurbanovo Geomagnetic Observatory, which was founded on September 30, 1900. Integration of InSAR transponder into current station architecture is also planned in 2022.

The gravimetric observatory equipped with the spring gravimeter gPhoneX #108 provides continuous time-varying gravity and atmospheric pressure data. The spring gravimeter gPhoneX #108 is installed on a concrete block isolated from the rest of the building grounding. The room containing gravimeter is thermally stabilized at around 22 ± 1°C using an air conditioning unit. An additional thermal polystyrene insulation is placed around the instrument further decreasing temperature variations on its surface. Concerning signal to noise ratio, the HUVO station can be characterized as moderately noisy.

The operation and maintenance of the HUVO gravimetric instrumentation is done mainly by the staff of the Slovak University of Technology. HUVO gravimetric observatory is also equipped with the accelerometer Raspberry Shake (4D) installed on the same concrete block as the spring gravimeter, operated by the staff of the Slovak Academy of Sciences. Several other meteorological sensors are also present at the site in the close vicinity of the gPhoneX #108: the meteorological station MWS 9-5, a well equipped with the ground-water level sensor and a total number of 16 sensors measuring the soil moisture. These sensors provide information necessary for modelling the gravity response associated with the variation of local hydrological masses.
