MEMS North Finder

MU6006

Product Advantages & Applications
The MU6006 MEMS north-seeking instrument is a reliable, cost-effective six-axis MEMS inertial sensor, suitable for navigation, control and measurement scenarios such as inertial navigation and attitude stabilization. Integrated with industry-leading MEMS gyroscopes and accelerometers in an independent structure, it features 100% domestically sourced electronic components; long-term high measurement accuracy is ensured via full-temperature parameter compensation.

Advanced Process & Technology
The module integrates leading-level MEMS gyroscopes and accelerometers, with built-in full-temperature compensation. Combined with overall vibration damping and sealing design, it can accurately measure the carrier’s motion parameters even in harsh environments, providing a low-cost and highly reliable solution. Meanwhile, relying on technologies like high-precision device manufacturing and full-temperature static/dynamic error compensation (including coning error), the product’s high performance and excellent user experience are guaranteed.
