sea gravimeter

基本解釋

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(dǎo)系統(tǒng)精度的重要設(shè)備，其重力傳感器的伺服回路決定著儀器的精度和動態(tài)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.
在采用垂直懸掛彈性系統(tǒng)的海洋重力儀中，由于彈簧本身的質(zhì)量不可忽略，受到水平擾動時就可能影響測量精度。
