Problems solved by technology

[0003] The calculation method of the traditional land-based launch vehicle platform transposition matrix directly uses the command value. When the platform is in the environment of the moving base, there is a large error between the actual transposition value of the platform and the command value. Directly using the command value to calculate the transposition matrix will bring a relatively large error. Large navigation calculation error

Abstract

The invention provides a moving base platform inclined leveling matrix computing method and device, and a storage medium. The moving base platform inclined leveling matrix computing method comprises the steps: 1, the transposition instruction altitude angle and the instruction azimuth angle are sent to a platform, and the platform returns the actual transposition value; 2, a matrix is calculated through the actual transposition value returned by the platform; and 3, through the transposition matrix, platform system add report output is converted to an inertial system. Through the actual platform transposition value, the platform system add report output after transposition is converted to the inertial system to conduct navigation calculation, the navigation error caused by the platform transposition error is avoided, and thus the navigation precision s improved.

Description

technical field [0001] The invention relates to the technical field of launch vehicle control, in particular to a calculation method, device and storage medium for a tilting and leveling matrix of a moving base platform. Background technique [0002] The launch vehicle control system mainly includes two parts: the guidance system and the attitude control system. Among them, the task of the guidance system is to issue shutdown commands, guidance commands and flight program angles at the right time during the flight of the rocket, so as to ensure that the rocket flies along the predetermined orbit, so as to accurately send the payload into the predetermined orbit. The starlight platform (referred to as the platform) is used for the navigation calculation of the launch vehicle. After the initial transposition of the launch vehicle to the star, it is necessary to calculate the platform transposition matrix, and convert the post-transposition platform system plus table output to ...
