sea gravimeter

基本解释

Marine, aerial and sea-bottom gravimeter measurements;
海洋、航空和海底重力測量；
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.
海洋重力儀是改善艦船慣導系統精度的重要設備，其重力傳感器的伺服廻路決定著儀器的精度和動態性能。
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.
在採用垂直懸掛彈性系統的海洋重力儀中，由於彈簧本身的質量不可忽略，受到水平擾動時就可能影響測量精度。
