SN-MIMU300S MEMS Inertial Measurement Unit

SN-MIMU300S MEMS Inertial Measurement Unit

This product is equipped with a high-precision survey-grade satellite receiver board, high-precision three-axis MEMS Gyro, and three-axis MEMS Accelerator. It is a Micro-Electro-Mechanical Systems (MEMS) Inertial/Satellite Combination Navigation System that enables single-antenna dynamic alignment or dual-antenna (RTK) high-precision rapid orientation. The product incorporates a new combination navigation algorithm engine and utilizes SF’s optimized design for antenna obstruction and multipath interference situations. It can effectively meet the long-duration, high-precision, and high-reliability navigation requirements in complex geographical environments such as cities and canyons.In optimal satellite conditions, it can provide centimeter-level positioning accuracy and maintain position, velocity, and attitude accuracy for an extended period.

This product is designed to be compact and lightweight, making it easy to use. It is suitable for a wide range of applications, including assisted driving, autonomous driving, vehicle positioning and orientation, AGV vehicles, power line inspections, platform stability, surveying and measurements, and precision agriculture, among many other fields.
