No interference compass heading sensor price high accuracy north finding sensor 3 axis yaw angle sensor supplier
General Description
The fiber optic gyro north seeker is mainly used to quickly and autonomously determine the true north direction, obtain the earth's rotation angular rate through fiber optic gyro tracking, calculate the earth's rotation angular rate signal, and calculate the angle between the gyro's main axis and the true north direction of the earth to provide a carrier Location information.The fiber optic gyro north seeker is mainly used to quickly and autonomously determine the true north direction, obtain the earth's rotation angular rate through fiber optic gyro tracking, calculate the earth's rotation angular rate signal, and calculate the angle between the gyro's main axis and the true north direction of the earth to provide a carrier Location information.

After power on, it start self-test. After the self-test
completed, it will response to the upper computer’s north seek command. And after north seeking, the north seeking result will be sent to upper computer. |
