Description

Technical field [0001] The invention relates to a rocket azimuth precision aiming system and method, which are used for initial aiming when a carrier rocket is launched. The invention belongs to the field of photoelectric aiming measurement. Background technique [0002] Before the launch of the launch vehicle, the azimuth of the rocket needs to be adjusted to accurately align it with the direction to be launched. This requires a sophisticated real-time measurement system to complete the azimuth positioning adjustment through real-time measurement of the azimuth angle. [0003] In the existing aiming and measuring systems, the visual aiming method is mostly used. The system includes a right-angle prism, a benchmark, two visual aiming units and two two-dimensional guide rails. The right-angle prism is installed horizontally on the rocket platform, the benchmark is placed at the fixed point of the benchmark after the geodetic survey, the two two-dimensional guide rails are respectiv...

Problems solved by technology

[0005] When the visual aiming method is used for aiming measurement, it is necessary to repeatedly perform two-dimensional rail translation and visual aiming to make it aim at the target, resulting in long measurement time and cumbersome work steps

In addition, due to the extensive use of human eyes for aiming, the accuracy of rocket azimuth aiming is relatively low, about 10″ or more. This level of accuracy can no longer meet the current requirement that the satellite’s azimuth aiming accuracy should reach about 2″.

At the same time, in order to protect the safety of the user's eyes, the visual receiving system can only use extremely low-energy lasers, resulting in the need to repeat multiple times during the daytime aiming process to align, which greatly affects the preparation time for rocket launch.
