The Technical and Operations Group (TOG) is made up of the personnel at the European VLBI Network (EVN) stations who provide the technical and operational expertise for operating the EVN as a VLBI array.
The GMVA Technical Group (GTG) provide service to Global Millimetre VLBI Array (GMVA), which combines European and US telescopes, and ALMA in ultra-high resolution observations at mm-wavelength.
Both groups are essential to maintain and improve these infrastructures in order to satisfy the requests for constantly increasing science goals and to sustain radio astronomy in the future.
The RadioNet supported meetings of EVN TOG and GTG takes place on May 22-23 2017, at the Ventspils University College (VUC) in Ventspils, Latvia (Ventspils International Radio Astronomy Centre is subdivision of VUC). More details here.
