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 …

Why it's free to use
- Filed August 30, 1995 and granted January 30, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 30, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 30, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
