ERICCO INERTIAL TECHNOLOGY ER-MNS-04A/B Quick MEMS north seeker for Heading machine Fast alignment in 30 seconds, user selectable fast alignment time: 30s, 60s, 90s Fast alignment accuracy 1° or 0.5° Modular design, OEM available 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. Technical Features 1. Adopt the latest MEMS gyro technology, with the ultimate volume compression, the size is 40×40×42 (with shell)/27×26×34 (inner table); 2. Adopt the latest three-axis MEMS gyro, three-axis MEMS plus meter strapdown inertial measurement technology; 3. Full solid-state design, built-in inner table, excellent impact and vibration resistance, and resistant to harsh environment; 4.
