IMU570 inertial navigation unit IMU sensor for Ocean & Underwater Surveying and Mapping
IMU570 INERTIAL NAVIGATION UNIT.pdf
▶ PRODUCT DESCRIPTION
IMU570 inertial navigation unit is composed of three-axis gyroscope, three-axis acceleration, temperature sensor and signal processing circuit. The three-axis angular rate of the carrier is measured, and the three angular rate data after error compensation (including temperature compensation, installation misalignment compensation, non-linear compensation, etc.) are output through RS422 / RS485 serial port according to the agreed communication protocol. The product adopts differential gyroscope structure, effectively restrains the influence of linear acceleration and vibration, and adopts full temperature compensation to suit the harsh environment of industrial application.
