Application Scenarios

north Finder application
The NF2000 is a high-precision fiber-optic gyroscope-based north finder designed to autonomously determine the true north direction. It combines fiber optic gyroscopes and MEMS sensors to provide accurate azimuth, roll, and pitch angle measurements with a north-seeking accuracy of ≤±0.3° (1σ). Ideal for outdoor navigation and attitude measurement, the NF2000 operates with a 24V DC power supply and supports RS-422 output. The device is lightweight, ≤2 kg, and offers a north-seeking time of ≤5 minutes. It is built for high durability with an operating temperature range of -40°C to +60°C.

NF7000A
 La serie NF7000-A es la buscador del norte que se utiliza para la orientación a bordo de barcos y no hay entrada de referencia externa, lo que hace que el entorno sea muy complejo. El buscador de norte por satélite (GPS o Beidou) no es adecuado para esta situación. Y la navegación a bordo requiere una navegación precisa en un espacio tridimensional. Cuando navega en el mar, el barco se ve afectado por diversos factores, como el viento, las olas y las corrientes oceánicas, y se enfrenta a movimientos multidimensionales que incluyen balanceo, cabeceo y guiñada, lo que resulta en una importante oscilación y movimiento angular del casco.
