The detailed product specifications are as follows:

1.1 Product Purpose

The gyro north seeker is used to rapidly and autonomously determine true north. It relies on two fundamental properties of the gyroscope – precession and rigidity – to achieve autonomous north-seeking. By tracking the earth's rotation rate with a high-precision fiber optic gyro and processing the resulting signal, the instrument computes the angle between the gyro's main axis and true north, providing azimuth information to the carrier platform.

1.2 Product Composition

The gyro north seeker is an electromechanical instrument consisting of a fiber optic gyro, an accelerometer, a mechanical rotation control mechanism, and an embedded computer.
