[0004] b) The manual measurement operation is complicated and takes a long time: due to the irregular structure of the special-shaped equipment vehicle itself, and the general roof height of at least several meters, manual measurement is difficult, poor in safety, and requires a long measurement time;
[0005] c) Poor popularization and applicability: the development trend of weapon systems is now precision strikes, and the precise positioning of each equipped vehicle is also required to be higher and higher, at least decimeter-level or higher positioning accuracy is required, while the position conversion errors of existing methods are all in meters class

The invention discloses a method for converting two point positions on a vehicle based on high-precision orientation technology. The method comprises steps of adding a satellite positioning antenna in advance to an actual measurement point, and jointly using a satellite high-precision orientation technology in combination with the satellite positioning antenna at a satellite antenna installation point to calculate the distance measurement value, the pitch angle measurement value and the azimuth angle measurement value between two points; changing the position of the vehicle, repeating the above steps according to the predetermined statistical magnitude and calculating the installation error of the azimuth angle; screening the above measurement values by the method of Thomson singular value elimination, and calculating the distance and pitch angle statistical values between the two points; measuring the actual measurement value of the azimuth angle of the actual measurement point when going out for tasks; and calculating the position information of the actual measurement point according to the actual position information of the satellite antenna installation point, the distance and pitch angle statistical values between the two points and the actual measurement value of the azimuth angle. The method can reduce the measurement error caused by the existing positioning method and improve the accuracy of position conversion.
Description
technical field [0001] The invention relates to the field of position conversion, and more specifically, to a method for converting two points on a vehicle based on high-precision orientation technology. Background technique [0002] At present, weapon systems around the world are developing in the direction of high precision, and various equipment vehicles have higher and higher requirements for positioning accuracy. In order to meet the demand, satellite positioning equipment is generally used for high-precision positioning. However, limited by the shape and function of the equipped vehicle and the visibility conditions required by the satellite positioning antenna, often the positioning antenna of the satellite positioning equipment cannot be installed on the required measurement point, and can only be installed on the sight point near the measurement point. For example, a radar vehicle needs to locate the center of the radar front, but the center of the radar front is fu...
