Problems solved by technology

However, the laboratory calibration method has high requirements on the solar simulator, that is, the solar simulator needs to have the characteristics of high brightness, high parallelism, high stability, and high uniformity at the same time, and the solar simulator that meets the above requirements is expensive. High cost and difficult to popularize
[0004] Aiming at the high cost of the solar simulator that provides the light source in the process of calibrating the solar sensor, no effective solution has been proposed so far

Abstract

The invention provides a device and method for calibrating a sun sensor outdoors.The device comprises a rotary table, a rotary table controller electrically connected with the rotary table, a ground inspection device connected with the sun sensor, and an intelligent terminal electrically connected with the rotary table controller and the ground inspection device.The intelligent terminal is adopted for determining the movement locus of the sun and determines the direction information of the rotary table according to the movement locus of the sun, so that the rotary table is controlled by the rotary table controller to rotate according to the movement locus of the sun, and then the sun sensor is calibrated.By means of the device and method, the sun sensor can be calibrated by directly utilizing natural light source, and the experiment cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of solar sensor measurement, in particular to a device and method for calibrating a solar sensor outdoors. Background technique [0002] The sun sensor is an important measurement component of the spacecraft attitude determination system. It can obtain the attitude information of the spacecraft relative to the sun by sensing the sun vector, and is widely used in the aerospace field. In order to obtain the measurement accuracy and true characteristics of the solar sensor, it is necessary to calibrate the solar sensor before it is put into use. [0003] At present, technicians usually use laboratory calibration methods to test the accuracy of solar sensors, that is, mainly use solar simulators to provide light sources for data collection and calibration of solar sensors. However, the laboratory calibration method has high requirements for the solar simulator, that is, the solar simulator needs to have the cha...
