Sun and moon tracking device and method suitable for motion state

Abstract

The invention discloses a sun and moon tracking device and method suitable for a motion state. The sun and moon tracking device comprises a two-dimensional rotary table, a tracking auxiliary device, a controller, an installation panel and a computer. The two-dimensional rotary table, the tracking auxiliary device and the controller are mounted on the installation panel; the two-dimensional rotary table is used for loading the detector and making the detector point to the sun or moon, the tracking auxiliary device is used for determining the azimuth angle and inclination angle of the initial mounting horizontal plane of the carrier, the controller is used for collecting image data of the tracking auxiliary device and transmitting the image data to the computer, and the computer is used for analyzing the image data and determining the inclination angle and azimuth angle of the horizontal plane; and then the two-dimensional rotary table is controlled to move through the controller so that the azimuth and pitching movement of the two-dimensional rotary table reaches a specified position, and the controller contains a GPS. The device has the advantages that the device can realize underway observation of the carrier, does not need to be installed at an accurate initial position, is simple and convenient, is easy to operate, and improves the atmospheric measurement level.

Description

technical field [0001] The invention relates to the technical field of optical characteristic detection, in particular to a sun and moon tracking device and method suitable for motion. Background technique [0002] The photometer or spectrometer of the sun and the moon is a common detection device for monitoring the optical characteristics of atmospheric aerosols and clouds. This kind of equipment often requires stable and long-term alignment of the sun and the moon, and requires high alignment and tracking accuracy , Therefore, this kind of equipment is generally installed on a fixed platform, and the initial installation requires strict alignment of the horizontal plane and initial orientation. In order to achieve long-term precise tracking, this kind of equipment is often equipped with a celestial body position sensor. When the celestial body is within the range of 5 degrees it points to, it can precisely point to the celestial body according to the attitude of the celest...

AI Technical Summary

Problems solved by technology

However, since the accuracy of the artificial installation cannot reach the absolute horizon and azimuth of 0 degrees, the tracking according to the computer program often exceeds the tracking range of the sun-sensitive period, and the sun-aligned azimuth cannot be achieved, resulting in unusable data

In addition, for mobile platforms such as vehicles, ships, airplanes, and balloons (airships), due to the position shift and swing of vehicles and ships when they are in motion, the initial installation level and initial state of the orientation are always changing during the movement, and the initial position is no longer Approximate level, the initial orientation also changes and is not 0, therefore, conventional ground installation and tracking procedures cannot be applied to mobile platforms
