The product outputs the carrier's azimuth and inclination information in real time based on the attitude calculation principle of inertial navigation,cross-links with the carrier's main control system through CAN bus,outputs the carrier's azimuth and inclination information in real time after north seeking,and CAN receive the north seeking or reset instructions sent by the carrier's main control system,stray parameter configuration and CAN bus communication parameter configuration functions.Through the RS422 bus,the carrier azimuth and attitude information can be output in real time,and the test terminal can be cross- linked to realize the product compensation parameter configuration and software online loading function.The product displays the azimuth Angle,inclination Angle,total startup time,status time and status code information of the device in real time through the OLED display,which is the key component of the carrier to realize the azimuth attitude measurement and intelligent transformation.
