2. Technical Advantages
1) The accuracy can be customized, also can be widely used in many fields
ER-MNS-05 Triaxial MEMS North Seeker is a highly reliable and cost-effective combination of six-axis MEMS inertial sensors, which can be widely used in navigation, control and measurement fields represented by inertial navigation and attitude stabilization. ER-MNS-05 3 Axis MEMS North Seeker can be configured with different hardware and software according to the needs of users, so as to meet the needs of different users.
2) Advanced process and technology
The ER-MNS-05 3 axis MEMS North Seeker integrates high-performance MEMS gyroscope and MEMS accelerometer in an independent structure. The gyroscope and accelerometer selected in the module represent the leading level of MEMS process inertial devices. The three-axis MEMS gyroscope is sensitive to the angular motion of the carrier, and the three-axis MEMS accelerometer is sensitive to the linear acceleration of the carrier. The zero position, scale factor, non-orthogonal error and acceleration related terms of the whole temperature parameter are compensated inside the module. It can also maintain high measurement accuracy for a long time. At the same time, the module adopts the overall vibration reduction, sealing design and other measures to ensure that the product can still accurately measure the angular and linear motion parameters of the carrier in the harsh environment, so as to provide users with a low-cost and high reliability solution.
3) High precision components manufacturing and system calibration compensation technology.
We have accumulated a series of key technologies in the research and development process of this project to ensure the high performance of the products. At the same time, the system adopts high-speed sampling, static error compensation (zero position, scale factor, installation error and other fine compensation in the whole temperature zone), dynamic error compensation and other technologies, to ensure that the product during the use process to achieve the best performance.
4) High quality and reliability
Through the comprehensive control of upstream and downstream processes and technologies, the company can effectively improve product quality and reduce system costs. At the same time, the company implements ISO9001 and GJB quality systems adopt strict processes to ensure the reliability and consistency of product performance.
Especially in the desert and other outdoor areas, the precision of traditional geomagnetic north finding schemes is not high. ER-MNS-05 Triaxial MEMS North Seeker produced by our company has the characteristics of being free from environmental interference, high precision measurement, small size and low power consumption, which can well meet the above requirements.
