Abstract

The invention discloses a satellite loss prevention remote guidance aircraft considering full-range coverage. The aircraft can strike a long-range target, a medium-range target and a short-range target, and is capable of avoiding out-of-control under the condition of staged satellite loss, thereby having important engineering significance. The remote guidance aircraft particularly comprises a decision making module and a central processing module, wherein the decision making module is used for selecting a guidance starting control module for executing work according to range information beforelaunching; and different guidance starting control modules can control different assembly modules to start to work, so that the corresponding assembly modules are controlled according to different ranges. The central processing module generates a rudder deviation instruction by receiving information transmitted by the assembly module and controls the aircraft to fly to a target, and a quasi-satellite guidance resolving sub-module capable of fitting a satellite signal during satellite loss is arranged in the satellite guidance module, so that the aircraft is ensured not to be out of control during satellite loss.

Description

technical field

[0001] The invention relates to a remote guided aircraft, in particular to an anti-lost satellite remote guided aircraft with full range coverage. Background technique

[0002] Long-range guided aircraft can carry out precise strikes on long-distance targets. In order to achieve long-distance precise strikes, remote-guided aircrafts are generally equipped with rocket range-extending modules, satellite signal receiving modules, and inertial navigation modules. The module increases the range of the aircraft, especially the range before control, and receives satellite signals through the satellite signal receiving module, so as to calculate the position information of the aircraft and the speed information of the aircraft in real time, and sense the attitude information of the aircraft through the inertial navigation module;

[0003] Also due to the above-mentioned modules, the remote guidance and control aircraft cannot accurately strike medium-range targets, a...

Examples

experiment example

[0188] In order to verify that the anti-lost satellite long-range guided aircraft provided by this application has the actual capability of taking into account the full range, through simulation, use the aircraft provided by this application to target multiple ballistics / flight trajectories for targets within different ranges , specifically, the system launches the aircraft provided by the application respectively for the targets at 8km, 15km, 20km, 28km, and 35km, and obtains as follows Figure 4 5 flight trajectory diagrams shown in the figure, it can be seen from the figure that the aircraft can just land at the predetermined range distance and can hit the target, that is, the aircraft provided by this application can also hit the target on the basis of being able to hit the remote target long-range targets or even short-range targets.

[0189] Further, for the target at 35km, launch three aircrafts provided by the application again, wherein, during the simulation process, ...
