The invention provides a strapdown laser inertial navigation device for an unmanned aerial vehicle and the unmanned aerial vehicle, and relates to the technical field of navigation equipment. The strapdown laser inertial navigation device for the unmanned aerial vehicle comprises a plurality of laser gyroscopes, an accelerometer, a gyroscope circuit assembly, a navigation computer circuit assembly, a body assembly and a box body assembly, the laser gyroscopes are used for collecting angle information and share the gyroscope circuit assembly and the navigation computer circuit assembly. The accelerometer is used for collecting speed information; the gyroscope circuit assembly is used for realizing state control of the laser gyroscope; the navigation computer circuit assembly is used for performing navigation calculation and attitude calculation according to the angle information and the speed information; the body assembly is used for rigidly connecting the laser gyroscope and the accelerometer in a strapdown manner; the box body assembly is used for installing the gyroscope circuit assembly and the navigation computer circuit assembly. Compared with traditional laser inertial navigation equipment, the size and the weight are greatly reduced, and the requirement of unmanned equipment for load lightweight can be met.
