Normally found in standard inertial reference systems, gyro-compassing enables the unit to establish precise heading within moments, without the use of a magnetic flux valve or magnetometer.
通常放置在标准惯性参考系统中，陀螺仪能够使设备在瞬间建立精确的航向，而不使用磁通阀或者磁力计。

This can be practical useful to the design of magnetic shielding for ring laser gyro.
这对于设计激光陀螺的磁屏蔽结构具有一定的实用价值。
