ER-MNS-04A/B Quick MEMS North Seeker for Heading Machine
Introduction
ER-MNS-04A/B fast 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. Mainly used in scenarios that require fast alignment.
By sensing the horizontal component of the earth's rotational angular velocity, the true north direction is measured without relying on an external reference benchmark, providing a high-precision azimuth benchmark for complex environments. The fastest fast alignment is 30s, and the user can choose 30s, 60s, and 90s for the fast alignment time. The fast alignment accuracy can reach 1° or 0.5°.
It adopts three-axis MEMS gyroscope and three-axis MEMS accelerometer strapdown inertial measurement technology, embedded with the original "Chinese Tripod" structure 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, support flexible OEM customization, compatible with mainstream communication interfaces, and meet the needs of fast embedding in different scenarios.
