specific Embodiment approach

[0052] like figure 2 As shown, the autonomous guidance system receives binding data and online static calibration before the ammunition is launched, and independently completes multi-sensor data acquisition, real-time online calibration, air initial alignment, multi-source fusion navigation, and terminal matching guidance after launch. Autonomous navigation and guidance without relying on satellite navigation. The specific implementation of the above functions is as follows:

[0053] (1) Data binding. The binding data received by the autonomous guidance system includes the launch point longitude, latitude, altitude, firing rate, firing direction, firing angle, target point longitude, latitude, altitude, infrared or visible light image of the target to be attacked.

[0054] (2) Data collection. The data collected by the autonomous guidance system includes 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer, barometric altimeter and other sensor data, as well as infr...

Abstract

The invention discloses an extended range guided munition autonomous guiding system independent of satellite navigation. The guiding system comprises a multi-source fusion guiding sub system, a terminal guiding sub system, a control and driving unit and a battery, wherein the multi-source fusion guiding sub system consists of a gyroscope, an accelerometer, a magnetometer, a barometric altimeter, amicroprocessor and a peripheral circuit; the terminal guiding sub system comprises an infrared or visible light active guiding head, an image processing computer and a peripheral circuit; the autonomous guiding system is electrified before munition is shot; bound data is received; functions of multi-sensor data acquisition, real-time on-line calibration, air initial alignment, multi-source fusionguiding, terminal matching guiding and the like are finished after shooting; autonomous navigation and guiding are realized independent of satellite navigation; and the autonomous guiding system is applicable to precise guiding missions in absence of satellite navigation signals in a modern war environment.

Description

technical field [0001] The invention belongs to the technical field of navigation guidance and control, in particular to an autonomous guidance system for extended-range guided munitions independent of satellite navigation. Background technique [0002] Extended-range guided ammunition is a kind of ammunition launched from a conventional weapon platform. During the flight, the ballistic elements or target information are measured in real time, the ballistic deviation is calculated and the corresponding correction actuator is controlled, and the ballistic is corrected one or more times, thereby Improve shooting accuracy. Extended-range guided ammunition usually needs to withstand harsh conditions such as high overload and high speed, and it uses the same high-speed rotational motion of the projectile body as conventional ammunition. The correction of extended-range guided munitions during flight needs to rely on accurate guidance information. Under the condition of satellit...
