Description

Technical Field

[0001] The present invention belongs to the technical field of Beidou high-precision space-time positioning, and specifically relates to a Beidou high-precision space-time reference determination method and device based on a gun-launched reference projectile. Background Art

[0002] The United States was the first country in the world to propose the concept of trajectory correction projectiles, with the main purpose of making up for the defects between the current uncontrolled 70mm rockets and the Heilfa anti-tank missiles. Subsequently, countries such as Russia, Germany, Britain, France, and Israel began to pay attention to the research and development of products for precision guidance of ground artillery at a relatively low cost. In the past decade or so, since the trajectory correction technology based on GPS satellite navigation technology was proposed, it has opened up a road to precision intelligent ammunition with low cost and high accuracy.

[0003] Afterwards, countries led by the United States and the Soviet Union conducted relevant research and development of terminal guided missiles and achieved some results. However, all of the above-mentioned guided artillery shells are based on the principle of laser guidance. Although this semi-active homing laser guidance technology requires a small space size, low manufacturing cost and high strike accuracy, it has two obvious disadvantages: first, it is easily affected by weather changes and war environment, especially the smoke and dust on the battlefield will seriously interfere with the transmission of the laser, causing it to deviate from the target and reduce the strike accuracy; second, such guided weapons require special combat personnel or aircraft and other equipment at the front of the position for laser guidance. In this case, combat personnel or aircraft and other equipment need to cooperate with artillery shells to be exposed to the enemy's firepower strike range for a long time, increasing unnecessary casualties and reducing the purpose of precision strikes.

[0004] In response to the above defects in laser guidance technology, countries such as the United Kingdom, the United States, and Russia have once again launched the research and development of ballistic correction technology using GPS satellite navigation technology. Although great progress has been made in the research of precision-guided munitions at home and abroad, when faced with precision strike operations such as "surgical precision strikes" and "decapitation operations", its positioning means are single, and the positioning accuracy still cannot effectively meet the combat needs, and it is also unable to provide high-precision real-time calibration of the target area. There is a lack of sufficient technical support for real-time situation awareness, intelligent command decision-making, and target damage assessment in the target area. Summary of the invention

[0020] Preferably, the control module of the present invention is used to issue a second control command to control the land attack platform to launch a cannon-launched Beidou high-precision relay missile to the target area to relay the signal of the cannon-launched Beidou high-precision reference missile.

[0021] Preferably, the device of the present invention further includes a signal receiving module and a fusion processing module

[0036] Example 1

[0037] When implementing precision strike operations, the positioning accuracy of unknown area targets is not high enough to effectively meet the needs; at the same time, in the process of implementing precision strikes, it is impossible to provide accurate real-time calibration of unknown target areas, and there is a lack of sufficient technical support for real-time situation awareness, intelligent command decision-making and target damage assessment in the target area. Based on this, this embodiment proposes a Beidou high-precision space-time reference determination method based on artillery-launched reference projectiles, such as Figure 1 As shown, the method of this embodiment obtains the precise geographic location signal of the impact point by using a cannon-fired Beidou high-precision reference missile, and provides broadcast / Beidou ground-based augmentation services to improve Beidou positioning accuracy; the method of this embodiment also realizes signal relay between the attack platform and the reference missile by using a cannon-fired Beidou high-precision relay missile; finally, the method of this embodiment also realizes Beidou-based high-precision real-time map positioning of the target area by fusing the precise location information of the impact point of the cannon-fired Beidou high-precision reference missile with the high-resolution image of the satellite or UAV.

[0040] This embodiment controls the land attack platform to launch a cannon-launched Beidou high-precision reference missile, which is dropped and parachuted after reaching the target area. It lands on the ground in a nearly vertical posture and penetrates the ground. The impact point is then colored and powered on. A high-precision geographic location coordinate signal based on Beidou is provided for the impact point within a certain period of time, while broadcast / Beidou ground-based augmentation services are provided to improve Beidou positioning accuracy.

[0041] S2, controls the land attack platform to launch the artillery-launched Beidou high-precision relay missile to the target area to relay the signal of the artillery-launched Beidou high-precision reference missile.

[0045] In this embodiment, high-resolution images of the impact point area of ​​the Beidou high-precision reference projectile fired by the artillery are taken by satellite or unmanned aerial vehicle.

[0046] This embodiment uses existing fusion technology to achieve the fusion of image-based location identification information, GIS information, Beidou location information and other information, which will not be repeated here.
