GNSS/INS MEMS Integrated Navigation System Designed for Performance

LKF-MN300 GNSS/INS integrated navigation system is a high-performance MEMS measurement equipment for attitude and position, which can be used in navigation, control, dynamic measurement and other fields. The LKF-MN300 integrates a high-performance MEMS inertial measurement unit (IMU), a GNSS receiver and a variety of other navigation sensors in an independent structure. The IMU uses three-axis high-precision MEMS gyroscope to sense the angular motion of the carrier, which outputs digital signals proportional to the angular velocity of the carrier. Three MEMS accelerometers are orthogonally configurated to sense the linear acceleration of the carrier. The gyroscopes and accelerometers selected by IMU represent the leading level of inertial devices in MEMS technology, which ensure that the integrated navigation system can maintain high navigation accuracy even when the signal of GNSS is invalid. At the same time, strict technology is adopted to ensure that the product can still accurately measure the angular motion and linear motion parameters of the carrier in harsh environment. LKF-MN300 GNSS/INS integrated navigation system is a high precision and high reliability solution.

Designed for Cost-effective and Stability

Compared with other gyroscopic technologies, MEMS has a significant cost advantage. At the same time, LKF-MN300 integrates three-axis magnetic sensor, barometric altimeter and GPS/BDII dual-mode satellite navigation receiver. The measurement accuracy of inertial devices is guaranteed by multi-compensation technology. Two different but complementary navigation modes, Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS), are integrated by using the optimal estimation method. INS have the advantages of full autonomy and can provide stable and continuous navigation information at high frequency. Combining the GNSS advantage of high position accuracy, LKF-MN300 can output stable and continuous three-dimensional navigation information under the condition that satellite signals are not available, which guarantees the optimal navigation performance under dynamic conditions.

Ideal for precision agriculture and port logistics automation. LKF-MN300 provides a high precision and high reliability, and has a significant cost advantage.
