Ultra-high precision MEMS north seeker for Heading machine
Introduction
The ER-MNS-05C MEMS north seeker adopts the latest MEMS gyro technology, breaking through the volume and performance limitations of traditional directional equipment, compressing the volume to the extreme, meeting the integrated operation requirements, and can be easily embedded in various small devices or complex systems.
By sensing the horizontal component of the earth's rotational angular velocity, the true north direction measurement is achieved without relying on an external reference benchmark, providing a high-precision azimuth benchmark for complex environments. The north-seeking accuracy is as high as 0.25°, breaking through the accuracy of MEMS north finders on the market, and can be used in high-precision north-seeking and volume-demanding scenarios.
It adopts three-axis MEMS gyroscope and three-axis MEMS accelerometer strapdown inertial measurement technology, embedded in the inner platform, through the all-solid-state design without moving parts and high-density packaging, it has strong stability, can withstand strong impact and vibration, and stably output reliable north-seeking data in complex environments.
Modular design supports flexible OEM customization, is compatible with mainstream communication interfaces, and meets the needs of rapid embedding in different scenarios.
