Abstract
Metsähovi Geodetic Research Station (MGRS) of the National Land Survey of Finland, located in Southern Finland at 60° North, has over the past 45 years constantly produced high-quality geodetic data for the geodetic community and for geodynamics research. The measurements started with Satellite Laser Ranging (SLR) in 1978 and have since expanded to include all major geodetic measurement techniques, including Global Navigation Satellite Systems (GNSS), Very Long Baseline Interferometry (VLBI), Doppler Orbitography and Radio-positioning Integrated by Satellite instrument (DORIS), and superconductive and absolute gravimetry, all co-located at MGRS. Over the past decade MGRS has undergone an extensive instrumentation and infrastructure upgrade in order to respond to the data quality and quantity requirements for a 1 mm global reference frame, as set out by the Global Geodetic Observing System (GGOS) and various other services under the International Association of Geodesy (IAG). MGRS is also an integral part of Finland's contribution to the UN General Assembly's 2015 resolution 69/266 A “Global geodetic reference frame for sustainable development”. GGOS geodetic core stations, such as MGRS, form the backbone for maintaining the International Terrestrial Reference Frame (ITRF), monitoring the orientation of the Earth in space, global tectonic movements, and producing information for computing precise orbits of satellites, including positioning satellites. The stability of the stations and their long series of observations is paramount for both global and regional geodetic networks. We present the instrumentation at Metsähovi, status of their operation, and how they contribute to various IAG services and to geodetic and geodynamics research.
