sea gravimeter

基本解释

Marine, aerial and sea-bottom gravimeter measurements;
海洋、航空和海底重力测量；
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.
在采用垂直悬挂弹性系统的海洋重力仪中，由于弹簧本身的质量不可忽略，受到水平扰动时就可能影响测量精度。
