Smartnoble is a leading global provider of high-precision navigation and positioning devices, offering reliable attitude and azimuth measurement solutions for defense, aviation, maritime, and industrial applications. The Fiber Optic North Seeker series integrates high-precision fiber optic gyroscopes, three-axis accelerometers, and mechanical rotation components to achieve fast and accurate north-seeking. It is widely used in radar antenna alignment, missile azimuth reference, mining orientation, surveying, and navigation stations.
The Fiber Optic North Seeker leverages the Earth's rotation and horizontal attitude sensitivity of a high-precision fiber optic gyroscope, along with gravity information from a triaxial accelerometer, to achieve high-precision pitch, roll, and azimuth measurements. Combined with latitude and longitude compensation technology, it effectively eliminates bias errors and improves north-seeking accuracy. The fully sealed aluminum alloy housing provides stable operation in extreme temperatures and is waterproof, moisture-proof, and dust-proof, making it suitable for harsh environments.
