Application Scenarios
The NF4030 is a high-performance FOG-based north seeker that integrates three-axis fiber optic gyroscopes and three-axis quartz flexible accelerometers, delivering full-temperature compensated inertial/attitude (including north-finding) outputs via RS422/RS232/Ethernet (up to 200 Hz)—well-suited for applications such as inertial navigation and attitude stabilization for UAVs, electro-optical pods, and underwater robots.
FAQ
The NF7700 north finder is primarily used for quickly and autonomously determining the true north direction, calculating and outputting the heading angle (the angle relative to true north). The north finder is an electromechanical integrated product, consisting of a fiber optic gyroscope, accelerometer, mechanical rotation control device, embedded computer, and mounting base. The north finder is an inertial measurement system that utilizes the gyro principle to measure the projection direction of the Earth's rotation angular rate on the local horizontal plane (i.e., true north direction).

NF7000-A series is the north finder which is used for ship borne orientation and there is no external reference input, making the environment very complex. The satellite (GPS or Beidou) north finder is not suitable for this situation. And shipborne navigation requires precise navigation in three-dimensional space. When sailing at sea, the ship is affected by various factors such as wind, waves, and ocean currents, and faces multidimensional movements including roll, pitch, and yaw, resulting in significant sway and angular motion of the hull.
