METODO PARA SINTONIZAR LAS PROPIEDADES DE UN GRADIOMETRO DE GRAVEDAD PARA MEDIR LOS COMPONENTES DEL TENSOR DE GRADIENTE GRAVITACIONAL QUE COMPRENDE LA APLICACION DE UN VOLTAJE DE POLARIZACION NEGATIVA EN AL MENOS UNO DE LOS CAPACITORES A FIN DE GENER

摘要

The present invention provides a method of tuning properties of a gravity gradiometer for measuring components of the gravity gradient tensor. The gravity gradiometer comprises a pair of first and second transversely arranged sensor masses that are arranged for movement about an axis and relative to each other in response to a gravity gradient. The gravity gradiometer further comprises first and second capacitors for sensing and influencing the movement of the first and second sensor masses. The method comprising applying a bias voltage to at least one of the capacitors for generating an electrostatic force which acts on one of the sensor masses and thereby influences the movement of that sensor mass.
