Développement d’une méthode innovante pour l’ajustement des paramètres internes du système de gravimétrie sous-marine GraviMob

Abstract : The GraviMob mobile gravimetry system, is a simple and innovative system that measures the 3 components of the gravity vector on the seabed, using six capacitive accelerometers divided into two triads. The processing of the measurements requires knowledge of eleven internal parameters, the determination of which is essential to estimate the three components or the norm of g. The values of these parameters vary depending on the temperature. The adjustment of these internal parameters in a climatic chamber, made it possible to trace their evolution, and thus to propose, and statistically validate, polynomial models of degree 4, making it possible to determine the value of each parameter as a function of the temperature over a measuring range of 4°C to 18°C.
