VGOS-compatible VLBI Radio Telescope System (VGOS)

Geodetic Very Long Baseline Interferometry (GeoVLBI) is one of the space geodetic observing techniques that contributes to the definition and maintenance of the International Terrestrial and Celestial Reference Frames (ITRF and ICRF), Earth Orientation Parameters (EOP) estimation. The new generation of GeoVLBI observing technique, named VLBI2010 Global Observing System (VGOS), is developed to achieve: 1-mm position accuracy on global scales, continuous measurements of time series of station positions and Earth orientation parameters, and turnaround time to initial geodetic results of less than 24 hours. Strategies for achieving these goals include an increase in the number of observations per day, reduction of systematic errors, automation of operations and analysis.​

A new VGOS compatible radio telescope system will be built at Metsähovi Fundamental station. This project is funded by Finnish Ministry of Agriculture and Forestry and the National Land Survey. We aim for a 12-13 m radio telescope.  Additionally to the telescope an innovatively designed signal chain will be built.  The telescope is planned to be a part of the Global VLBI Observing network, coordinated by the International VLBI Service (IVS).
