Apparatus and method for sun and moon tracking in motion

Abstract

The invention discloses a sun and moon tracking device and method suitable for motion state, comprising: a two-dimensional turntable, a tracking auxiliary device, a controller, a mounting plate and a computer. The two-dimensional turntable, the tracking aid and the controller are installed on the mounting plate; the two-dimensional turntable is used to load the detector and make it point to the sun or the moon, and the tracking aid is used to determine the azimuth and inclination of the initial installation level of the vehicle, and control the The controller is used to collect the image data of the tracking auxiliary device and transmit it to the computer. The computer is used to analyze the image data, determine the horizontal plane inclination angle and the azimuth angle, and then control the movement of the two-dimensional turntable through the controller, so that the azimuth and pitch movements of the two-dimensional turntable can reach the Specify the location, the controller contains GPS. The advantages of the present invention are that the navigation observation of the vehicle can be realized, the installation at an accurate initial position is not required, the invention is simple, convenient, and easy to operate, and the atmospheric measurement level is improved.

Description

technical field [0001] The present invention relates to the technical field of optical characteristic detection, in particular to a sun and moon tracking device and method suitable for motion state. Background technique [0002] The photometer or spectrometer of the sun and the moon is a commonly used detection device for monitoring the optical properties of atmospheric aerosols and clouds. This device often requires stable and long-term alignment with 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 accurate tracking, this kind of equipment is often equipped with a celestial body position sensor. When the celestial body is located in the range of 5 degrees of its pointing, the posture of the celestial body sensor is adjusted according to the ...

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
