A Method to Improve the Positioning Accuracy of the Intersection of two Planes

As the payload of the reconnaissance aircraft, the positioning accuracy of the airborne photoelectric platform is the key to whether the weapon can achieve accurate strike and whether the battlefield information can be obtained accurately. This paper introduces the structure of the photoelectric measurement pod, establishes the auxiliary coordinate system of the positioning model. According to the homogeneous coordinate transformation method, rotates and transforms the parallax vector of two machines into the unified coordinate system, and completes the solution of the target according to the principle of space intersection. Combined with the disadvantages of traditional rendezvous positioning algorithm, an improved algorithm is proposed. Based on the model, the error factors affecting the positioning accuracy are determined, which provides theoretical guidance for engineering application. The simulation results show that the improved algorithm is better than the traditional algorithm.
