Method for position conversion of two points on special-shaped equipment vehicle

Abstract

The invention discloses a method for position conversion of two points on a special-shaped equipment vehicle. The method comprises the steps of using a satellite positioning antenna to measure position information of the satellite antenna installation point and the actual measurement point in advance, and calculating the distance between the two points and the measurement value of a pitch angle; repeatedly measuring preset counting quantity under the condition that the position of the special-shaped equipment vehicle is not changed, and repeatedly conducting the previous step; adopting a Thomson singular value elimination method to screen the measurement values of the preset counting quantity, and calculating the counting value of the distance between the two points and the counting valueof the pitch angle; measuring the actual measurement value of an azimuth angle of the actual measurement point during an outing task; using the satellite positioning antenna to measure the position information of the satellite antenna installation point, adopting the counting value of the distance between the two points, the counting value of the pitch angle and the actual measurement value of theazimuth angle to calculate the position information of the actual measurement point. The used conversion method can improve the accuracy of the position conversion.

Description

technical field [0001] The invention relates to the field of position conversion, and more specifically, to a two-point position conversion method on a special-shaped equipped vehicle. 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 full of precision ele...

Problems solved by technology

[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
