Abstract
The essential principle of magnetic suspension gyroscope north-seeking is introduced.And the rotation rate of the earth is decompounded onto the gyro coordinate.The north-seeking error which is caused by position transformation error is analyzed.The relational expression between position transformation error and north-seeking error is derived
which can provide theory foundation for position transformation error compensation
and can provide technical support for improving north-seeking speed.
