ADI MEMS IMU helps Huace pocket RTK achieve efficient and high-precision positioning

RTK mobile receivers are widely used in fields such as autonomous driving, engineering surveying, and conventional mapping. By receiving satellite signals and the observation information of the reference station on the satellite, the three-dimensional coordinates of the mobile station are solved in real time according to the principle of relative positioning. Currently, most RTK products on the market use geomagnetic solution to measure inclination, which is easily affected by external environmental interference. Even RTK with inertial navigation, many are large and bulky, and easily affected by ambient temperature. Huace Navigation, a leading company in high-precision satellite navigation and positioning, uses ADI's high-precision IMU inertial measurement unit in its latest pocket RTK, which can effectively solve these problems and achieve high-precision positioning in complex environments with a wide inclination range of ±60°, making portable RTK more efficient and stable.

Zhang Jialin, Project Manager at Huace Navigation, said: “The new generation of RTK has achieved a small size while still integrating inertial navigation to improve the working method, enhance working efficiency and positioning accuracy, thanks to ADI’s high-performance technology and solutions in the field of inertial navigation. We are very pleased to work with ADI to continue to develop more industry-leading products.”

ADI's inertial measurement units combine precision gyroscopes and accelerometers in a multi-axis manner, and can reliably detect and process multiple degrees of freedom information even in extremely complex applications and dynamic environments. These modular solutions include complete factory calibration, embedded compensation and sensor processing, and simple programmable interfaces. They have excellent accuracy and stability, as well as small size and low power consumption, making them ideal for applications such as high-precision positioning and navigation.

Tony Zarola, general manager of the Inertial MEMS and Sensor Technology Division of Analog Devices, pointed out: "ADI has decades of deep accumulation in the field of inertial navigation measurement. Regardless of the size, each high-precision inertial navigation measurement unit has undergone several hours of temperature compensation calibration before leaving the factory, and has made comprehensive measurements and compensation for parameters such as zero point, sensitivity, cross sensitivity, and the influence of motion acceleration. The architecture, packaging, and process design of the core sensor of ADI's inertial navigation measurement unit all take long-term stability into consideration, ensuring the long-term reliability of user products."
