摘要：
An apparatus for azimuth measurements is provided. The apparatus comprises a housing and a plurality of gyro sensors aligned in the housing. Each of the plurality of gyro sensors has an input axis for angular velocity measurements. There is provided a drive unit for rotating each of the plurality of gyro sensors about a rotation axis. Each of the plurality of gyro sensors changes orientation of the input axis with the drive unit.
