When a NGIMU system is working, an inevitable staticcoupling error and dynamic coupling error occur.
NGIMU系统在运行时，不可避免地存在静态和动态耦合误差。

The result shows that the staticcoupling of longitudinal motions to the rolling equation is not exist, the coupling between them is mainly caused by waves.
结果表明，纵向运动对横摇的非线性静力耦合作用不存在，它们之间的耦合主要是由波浪引起的。

Reasonable laying space and effective screen earthing, which can reduce the static electricity coupling interference.
