The present invention is a method for acquiring attitude parameters of a carrier before firing, and provides a method for acquiring the geographic location and attitude of a carrier by using an ultra-wideband sensor base station and a sensor tag, including the following steps: Coordinate system; Arrange sensor base stations around the launch position, and accurately locate the sensor base station in the geodetic coordinate system; Establish a carrier coordinate system; When the carrier enters the launch position, use the sensor base station to locate the sensor tag array: Use sensor tags The information calculates the transformation matrix between the geodetic coordinate system and the carrier coordinate system, and realizes the aiming calculation; the present invention introduces the geodetic coordinate system into the traditional UWB positioning, and combines the geodetic coordinate system with the position of the base station, so that the geographic location information of the carrier can be quickly obtained. It can replace the traditional aiming method to realize the process of obtaining the attitude parameters of the vehicle. |
