Sea gravimeter is an important equipment for improving the precision of navy inertial navigation systems. The servo loop of gravity sensor determines its precision and dynamic properties. On the basis of introducing the structure and working principle of the zero length spring-based gravity sensor, the configuration and design method of the servo loop is studied, the influence of some key parameters upon system properties is analyzed, and its properties in time domain are investigated. It plays an important role in the development of the sea-gravimeter.
