A North Finder, also called a North Seeker, is a precision navigation device used to determine true north without relying on external navigation signals.

Most modern North Finding systems use gyroscopes and accelerometers to detect the Earth's rotation and gravity direction. By analyzing these measurements through advanced algorithms, the system can calculate the true north direction accurately.

Compared with magnetic compasses, gyro-based North Finders are less affected by magnetic interference from surrounding environments, making them suitable for applications requiring higher accuracy.

North Finders are widely used in:

• Surveying and mapping
• Geological exploration
• Military navigation
• Tunnel engineering
• Autonomous systems

Ericco provides North Finding solutions based on advanced inertial technologies, including MEMS and Fiber Optic Gyroscope technologies, to support high-precision direction measurement requirements.

Three things matter most:

(1) mount the unit on a stable, rigid base close to level most MEMS models compensate tilt within a ±30° range, but a level base gives best results;

(2) keep the unit still for the full alignment time accuracy directly trades off against alignment time (e.g. 30 s for 1°, 90 s+ for 0.5° on ER-MNS-04);

(3) avoid strong continuous vibration or magnetic field sources near the unit during alignment. Provide your local latitude if the model requires it.

Yes, this is the core design target. Gyro north seekers are magnetically immune by principle, and MEMS models are built for harsh environments: full solid-state, impact/vibration-resistant designs, and operating temperature ranges such as -40 °C to +70 °C. Examples include ER-MNS-10A (only 14 mm thick, 40 g, for underground coal-mine hydraulic supports) and ER-MNS-09 (Ø30/25.4/18.6 mm directional modules for downhole trajectory measurement). For explosive atmospheres, confirm intrinsically-safe / certification requirements with us before ordering.

Static (alignment) north seeking measures true north while the carrier is stationary, outputting a single azimuth reference. Dynamic north seeking adds continuous tracking: after alignment it holds and updates the heading as the carrier rotates or moves. e.g. ER-MNS-05A for heading machines provides 0.5° alignment and holds 0.5° over 20 minutes of dynamic motion. If your rig, tunnel boring machine or drill rotates during operation, you need a dynamic model.
