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.
海洋重力仪是改善舰船惯导系统精度的重要设备,其重力传感器的伺服回路决定着仪器的精度和动态性能。
in the measurment of gravity at sea by a sea gravimeter with a vertical hanging spring of non-negible mass, the measurment accuracy of gravity may be influenced by the horizontal accelerations.
