 Micro-gyro north seeking   HT-INS-100

(Weight only 65g;With heading keeping ability)

         

 

Product characteristics

1.High precision, small size, long-term stability.           

2.Full temperature compensation.

3.Strong ability to withstand impact vibration.

4.Zero bias stability : Allan Variance 0.02° / h.

5. Completely independent gyro north seeking, free from ferromagnetism and external environment interference.

6. After the completion of north seeking, the heading keeping accuracy in motion is less than 0.3 °/h.

 

Product description

            HT-INS-100 is a small-volume, high-precision MEMS inertial measurement unit, which integrates three-axis high-precision MEMS gyroscope, three-axis high-precision MEMS accelerometer, and full-temperature compensation before the product is out of the factory to ensure its stable performance in complex temperature environment. The products are widely used in intelligent handling robots ( AGV ), autonomous underwater vehicles ( AUV ), industrial equipment, measurement / map, stable platform, transportation, unmanned aerial vehicles ( UAV ), and unmanned ground vehicles ( UGV ).
