Anti-lost satellite remote guidance aircraft with full range coverage

Abstract

The invention discloses an anti-lost satellite long-range guidance aircraft with full-range coverage, which can achieve strikes on long-range targets, medium-range targets and short-range targets, and can not lose control in the case of staged star loss. Important engineering significance, specifically, the remote guided aircraft includes a decision-making module and a central processing module, and the decision-making module is used to select a guidance and control module to perform work according to the range information before launch; different guidance and control modules can control Different component modules start to work, so as to control the corresponding component modules due to different ranges. The central processing module generates rudder deviation instructions by receiving the information transmitted by the component modules, and controls the aircraft to fly to the target. There is a quasi-satellite guidance solver module that can fit the satellite signal when the star is lost, so as to ensure that the aircraft does not lose control when the star is lost.

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...

[0003] Also due to being provided with the above-mentioned modules, the remote guidance and control aircraft cannot accurately strike medium-range targets, or even 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 the control is started, 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 the control is launched. 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 long-range guided aircraft are left, it is naturally difficult to properly deal with 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
