The application of two principal space geodetic techniques: Global Navigation Satellite System (GNSS) and Satellite Laser Ranging (SLR), is under discussion in this study. The objective is to discover geodynamic processes of the Earth’s crust in the territory of Latvia, placed at the coast of the Baltic Sea and at the edge of Fennoscandian land uplift phenomenon, by analysing GNSS time series obtained from Latvian GNSS permanent stations with reference to EUREF Permanent Network (EPN), and to develop additional observation device in relation to International Laser Ranging Service (ILRS) network.
