Embodiment Construction

[0040] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041]The embodiment of the present invention adopts the fixed-pointing computer based on the Godson processor. The fixed-pointing computer based on the Godson processor is a device that organically combines an inertial navigation device and an aiming device, wherein the inertial navigation device uses an inertial instrument sensitive motion carrier. Angular motion and linear motion, the aiming device is a three-measurement head aim...

Abstract

The invention provides a positioning aiming control method and device based on a Loongson processor aiming computer. The method comprises the steps: reading aiming instrument parameters based on the Loongson processor aiming computer; when inertial measurement unit vehicle length north-seeking or launching process north-seeking is completed and a system navigation state is entered, reading an inertial measurement unit prism azimuth angle and prism out-of-levelness, a three-measuring-head aiming controller lower light pipe collimation deviation angle, a satellite prism azimuth angle and prism out-of-levelness, and three aiming controller light pipe collimation deviation angles in real time; calculating a normal azimuth angle of an on-missile prism based on inertia, a normal azimuth angle ofthe on-missile prism based on satellite data and an optical axis pitch angle of a light pipe in real time by utilizing the read data; and performing positioning aiming control according to the normalazimuth angle of the on-missile prism based on inertia, the normal azimuth angle of the on-missile prism based on satellite data and the optical axis pitch angle of the light pipe.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a positioning and targeting control method and device based on a Godson processor targeting computer. Background technique [0002] As people put forward higher and higher requirements for the accuracy of positioning and navigation equipment, in order to achieve high-precision positioning and targeting algorithms, on the one hand, it is necessary to establish a more accurate system model; Information fusion is achieved. [0003] However, such a high-precision positioning and aiming method does not exist at present, so designing a control scheme for high-precision positioning and aiming becomes an urgent problem to be solved. Contents of the invention [0004] The present invention aims to provide a positioning and aiming control method and device based on a Loongson processor-based targeting computer that overcomes the above-mentioned problems or at least pa...
