The Study about the Laser-Gyrocompass North-seeking and Error Analysis

A scheme is presented about three-position-north-seeking with one RLG provides initial-alignment's standard for the ground-to-ground tactic missile,then the north-seeking error is analyzed and the methods to reduce the error are gained.They can provide references for developing laser gyrocompass north-seeking equipment to satisfy the demands of initial-alignment of the ground-to-ground tactic missile's launch.
