Embodiment 1

[0037] In the current implementation of precision strike operations, the positioning accuracy of targets in unknown areas is not high enough to effectively meet the needs; at the same time, during the implementation of precision strikes, accurate real-time calibration of unknown target areas cannot be provided, and real-time situational awareness and real-time situational awareness of target areas cannot be provided. Intelligent command decision-making and target damage assessment lack sufficient technical support. Based on this, this embodiment proposes a Beidou high-precision space-time reference determination method based on artillery-fired reference projectiles, such as figure 1 As shown, the method of this embodiment obtains the precise geographical position signal of the impact point by using the cannon-fired Beidou high-precision reference projectile, and provides broadcast / Beidou ground-based enhancement services at the same time to improve the Beidou positioning accura...

Embodiment 2

[0054] This embodiment proposes a Beidou high-precision space-time reference determination device based on artillery-fired reference projectiles, such as Figure 4 As shown, it includes a control module, a signal receiving module and a fusion processing module.

[0055] Among them, the control module is used to issue the first control command, control the land attack platform to launch the Beidou high-precision reference projectile to the target area, and then automatically dye the impact point area, and provide the Beidou-based high-precision geographic position coordinate signal and broadcast / Beidou foundation enhancement.

[0056] The control module issues a second control command to control the land attack platform to launch the Beidou high-precision relay projectiles to the target area to relay the signal of the Beidou high-precision reference projectiles.

[0057] The signal receiving module is used to receive the signal of the Beidou high-precision relay projectile fi...

Abstract

The invention discloses a Beidou high-precision space-time reference determination method and device based on a gun-shot reference projectile, and the method comprises the steps: controlling a land attack platform to launch a gun-shot Beidou high-precision reference projectile to a target region, and then carrying out the automatic dyeing of an impact point region, and high-precision geographic position coordinate information based on Beidou and broadcast / Beidou ground-based enhancement are provided. According to the method, the Beidou high-precision reference bomb is shot, high-precision Beidou target area calibration is achieved, and Beidou ground-based augmentation service of an unknown area is provided. According to the invention, signal relay among the cannon-shot Beidou high-precision relay projectile, the time attack platform and the reference projectile is also adopted, so that the problem that the ground positioning signal launching distance of the cannon-shot Beidou high-precision reference projectile is not long is solved. And carrying out fusion processing on the accurate position information of the impact point of the reference missile and a satellite or unmanned aerial vehicle high-resolution image to realize Beidou-based high-precision real-time map calibration of an unknown area.

Description

technical field [0001] The invention belongs to the technical field of Beidou high-precision space-time positioning, and in particular relates to a Beidou high-precision space-time reference determination method and device based on artillery-fired reference projectiles. Background technique [0002] The United States is the first country in the world to propose the concept of a ballistic correction missile. Its main purpose is to make up for the current uncontrolled 70mm rocket and Haier anti-tank missile. Subsequently, Russia, Germany, Britain, France, Israel and other countries began to attach importance to the product development of precision-guided ground artillery at lower costs. In the past ten years, since the ballistic correction technology based on GPS satellite navigation technology was put forward, it has created a low-cost, high-precision intelligent ammunition precision road. [0003] After that, countries led by the United States and the Soviet Union carried o...
