MEMS Inertial Navigation System (MEMS INS) SN-MINS200S
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 Combined Navigation System capable of achieving single-antenna dynamic alignment or dual-antenna (RTK) high-precision rapid orientation. The product incorporates a new combined navigation algorithm engine and utilizes optimized design for satellite antenna obstruction and multi-path interference, making it well-suited for long-term, high-precision, and highly reliable navigation applications in complex geographical environments such as cities and canyons. In environments with good satellite coverage, it can provide centimeter-level positioning accuracy and maintain position, velocity, and attitude accuracy over extended periods.
The product is designed to be lightweight, compact, and user-friendly, making it suitable for various applications including assisted driving, autonomous driving, vehicle positioning and orientation, AGV vehicles, power line inspections, platform stability, surveying and mapping, precision agriculture, and so on.
