Satellite loss prevention remote guidance aircraft considering full-range coverage

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...

Problems solved by technology

[0003] Also due to the above-mentioned modules, the remote guidance and control aircraft cannot accurately strike medium-range targets, and even cannot strike short-range targets at all. Specifically, for medium-range targets, due to the existence of the rocket-range extension module, It is already close to the target when starting the control, and at this time the satellite signal receiving module and the inertial navigation module have just been powered on, the satellite signal receiving module needs a long time to obtain stable satellite signals, and the inertial navigation module cannot perform zero Position alignment, the sensitive attitude error is relatively large when the power is just turned on, so it is difficult to accurately hit the medium-range target; for the short-range target, due to the existence of the rocket’s range-extending module, it may have flown over the short-range target when starting the control Target, it is basically impossible to turn 360 degrees to strike

[0004] However, for some specific situations, such as when the short-range guided aircraft has been exhausted and only the long-range guided aircraft is left, it is naturally difficult to properly handle the sudden appearance of medium-range and short-range targets

[0005] In addition, in the actual work process, there are many reasons why the aircraft failed to hit the target in the end, and they are more complicated. One of the major reasons is that the satellite was lost during the guidance flight, and the aircraft lost control without satellite signals. Therefore, the aircraft In the design process, it is also necessary to study how to prevent the loss of stars, or how to ensure that the aircraft will not lose control in the event of star loss
