Mobile GNSS Park – GPSMob
GPSmob is one of Résif’s specific actions.
A range of instruments which acts as a complement to permanent networks
Résif-GPSMob is a range of mobile GNSS instruments (GPS, Glonass, Galileo) made available to the scientific community to carry out geodetic measurements over specific areas (without geographical restrictions) and over short periods of time (a few weeks).
The park included, in February 2021, 50 Leica GR25 receivers with their accessories (antenna, cables, internal batteries, chargers…), ruggedized laptops for field conditions, tripods, bipods, masts, collapsible solar panels, numerous cables and extensions, and other small accessories provided on request.
A refresh of the GPSMob mobile pool has been initiated in 2021. In September 2022, 40 Leica GR50 receivers and their AS11 antenna replaced the GR25/AS10 pairs acquired from 2013 to 2015.
Learn more about the 2021-2022 refresh.
In 2021, the GPSMob instrumental fleet had 50 mobile stations (including 40 new Leica GR50 receivers and their AS11 antenna) deployed during the year on 2674 measurement points that collected 0.5 GB of data. The database provides scientists with a total of 164 GB of data.

This image was taken at the KNKL seismological station, located in the commune of Kani-Keli, Mayotte. The site was instrumented as part of the CNRS-INSU Tellus project, following the seismic-volcanic crisis that began in May 2018. This site hosts three types of instruments: an accelerometer, a broadband seismometer and a GPS antenna from RESIF’s GPSMOB mobile park, visible on this image © J. Van der Woerd, Eost.
