Research on a perceptual system of small unmanned surface vehicle

Aiming at the problem that small unmanned surface vehicle (USV) are affected by wind waves, undercurrents and other factors affecting navigation safety, a navigation state perception system is designed. The system is equipped with high-precision six-axis attitude sensors, ship-borne smart terminals, GPRS wireless communication units and other equipment. Obtain the attitude information of the USV through the high-precision IMU six-axis attitude sensor, and provide data support for the remote operator's attitude control of the USV; calculate the heading angle through the shore-based terminal; build the ship-borne intelligent terminal through the GPRS wireless communication unit and the data transmission path of the shore-based terminal. The system satisfies the needs of USV sensing applications, and effectively realizes the detection of attitude and heading.
