North-Seeker

ET-2B North-seeker mainly constitutes by a high accuracy tuning gyro of biaxial power and two accelerometers. By measuring X Y axis weight of the Earth's rotation speed, determines the true north. It is insensitive to magnetic fields and other environmental factors. Combine with the two axial accelerometers, can measure and calibrate the tilt angle
