TJ-MIMU300S MEMS IMU
MEMS IMU
PRODUCT INTRODUCTION
This product is equipped with a high-precision surveying-grade satellite receiver board, a high-precision three-axis MEMS gyroscope, and a three-axis MEMS accelerometer, enabling a micro-electromechanical inertial/satellite integrated navigation system capable of single-antenna dynamic alignment or dual-antenna (RTK) high-precision rapid orientation. The product is equipped with a new integrated navigation sound-based antenna, utilizing SFE's optimized design for antenna obstruction and multipath interference scenarios. It effectively meets the demands for long-term, high-precision, and high-reliability navigation applications in complex geographical environments such as urban areas and canyons. It can provide centimeter-level positioning accuracy in environments with good satellite conditions and maintain position, velocity, and attitude accuracy over extended periods.
PRODUCT FEATURES
