The NF3500 is a high-precision inertial combined navigation system based on fiber optic gyroscopes and MEMS accelerometers. This product combines inertial sensors with satellite navigation systems (such as GPS, BDS, GLONASS, Galileo, etc.), achieving a complementary advantage between inertial and satellite navigation. It can provide real-time output for users including heading, attitude, speed, position, angular rate, acceleration, etc., offering more reliable and accurate navigation and positioning capabilities.

NF1070 MEMS North Finder (hereinafter referred to as NF1070) is a universal, miniaturized, industrial-grade inertial measurement unit. It enhances measurement accuracy by compensating for the zero bias and scale factor of each axis based on temperature. This north finder comprises a high-precision MEMS north-finding gyroscope (with the Z-axis gyro being of high precision), a MEMS accelerometer, a high-precision motor servo system, and peripheral circuits. Under static conditions, it outputs the attitude angle in the direction indicated by the product casing.
