Abstract
GPSMob is a fleet of mobile GNSS (GPS, Glonass, Galileo) National Instruments (PINs) made available to the scientific community to carry out geodetic measurements in specific areas over short periods of time (a few weeks). It is integrated into Epos-France as a Specific Action. The aim of the Specific Action is to support French scientific research using GNSS geodetic measurements from repeat campaigns, mainly as part of projects supported by or in conjunction with CNRS-INSU.
