Harfsen, Netherlands (November 20, 2014) – InfraRadar, an advanced mobile ground penetrating radar infrastructure locator, developed and manufactured here by GT Frontline, recently switched to the Spectra Precision SP80 GNSS receiver.  As company president, Dick van der Roest said, “This was done because you cannot do a good survey without a good position, and the SP80 performs significantly better than competing systems.”
