The invention relates to a device and a process for gravitation measurement with an acceleration sensor fitted on a moving support, a satellite navigation receiver and a computing unit in which use may be made of several acceleration sensors instead of one for vector gravimetry, the satellite navigation receiver must show the spatial location as well as the position in order fully to indicate the inertial acceleration and finally the computing unit may finally be used off-line for the combination of the measured total and inertial acceleration to determine the gravitation. The numeric filtering of the accelerations measured is considerably improved by the drafting of filter coefficients best suited to the stochastic properties of the gravitational field over a "physically blind" low-pass filtration. The invention makes it possible to use simpler and more economical acceleration meters, to find the vector gravimetry, i.e. the full gravitation vector, and determine finer structures of the earth's gravitational field by aircraft/ship gravimetry.
