Research and development

A fundamental task at the Satellite Geodetic Observatory is to follow, and to contribute to the state-of-the-art international developments of different space geodetic techniques (GNSS, InSAR, VLBI). New technologies have to be transferred and implemented in the practice. The SGO is responsible for the development and professional maintenance of the Hungarian high-level geodetic networks, as well as for their connection to the international networks. We maintain and develop the Hungarian GPS Geodynamic Reference Network. We operate a GNSS Analysis Centre to process EUREF and measurements. Our education activities include university courses, practical training, PhD supervision.

The appearance of space geodesy in the 1980s made it possible to commence research programs for the determination of movements of the major plates of the Earth's lithosphere.

Geodetic networks
For centuries, surveying and mapping were relying on traditional geodetic control networks with stable stone marks.

The advent of satellite positioning revolutionised field surveying. Based on the ground-based GNSS augmentation infrastructure, nowadays centimetre accurate positioning is available in real time, practically anywhere in the country.

Radar interferometry
One of the newest geodynamic measurement techniques, the Synthetic Aperture Radar Interferometry (InSAR), is very promising for geodetic, as well as for geophysical and geological applications.

Very Long Baseline Interferometry (VLBI) is a radio astronomical and space geodetic observing technique originally developed at the end of the 1960s.

GNSS interference
The weak radio signals of the navigation satellites are vulnerable to illegal distubing radiation emitted at the same frequency band.

With courses and lectures, university education and PhD supervision, we help the professional carreers.
