Abstract
The Action Spécifique Gravimetry of the French Research Infrastructure Epos-France is based on a mutualized national instrumental park offering scientific teams a range of measurement resources and services for the gravity field studies. It is drived by an office which aims to manage all activities in the field and runs the park. The range of instruments includes absolute and relative gravimeters of different classes and technologies. It allows covering a vast array of applications with which, among other things, it maintains the French observation networks, the "measurements" component of the Service National d'Observation Gravimétrie in France.
