“…This process helps to prevent the radiation performance of the satellite load from rapidly declining due to the rapid changes of the space environment. For instance, the IRMSS (infrared multispectral scan sensor) of the China-Pakistan Resources Satellite uses a single off-axis paraboloid mirror scheme to move the matching mirror out of the main optical path and adjust the low-temperature blackbody so that the blackbody cavity axis coincides with the optical axis of the calibration equipment [5], and the blackbody cavity outlet light bar is on the focal plane of the main mirror. This method is used to simulate the thermal infrared spectrum radiation source and calibrate the thermal infrared spectrum of the multispectral scanner [6].…”

“…It is extensively used in satellites to obtain high-frequency calibration coefficients, enabling sensors to measure thermal radiation information from target objects more accurately. Cryogenic space and reference blackbody are commonly used as radiation references in the thermal infrared spectrum segment [5]. Many sensors around the world use blackbodies for thermal infrared calibration, such as the MODIS (moderate-resolution imaging spectroradiometer) onboard calibration which utilizes high-temperature and low-temperature blackbodies and a heating and cooling multipoint calibration device [11,12].…”

“…TIRS uses the same method as MODIS to calibrate the entire optical path on the satellite [13]. CBERS-02 (China-Brazil Earth Resources Satellite-02) satellite uses a high-temperature cavity blackbody and a normal-temperature plane blackbody for calibration [5]. In addition, there are onboard calibration methods for moon and star observations.…”

Following the launch of the ZY1-02E satellite, the thermal infrared sensor aboard the satellite experienced alterations in the space environment, leading to varying degrees of attenuation in some components. The laboratory calibration accuracy could not satisfy the demands of quantitative production, and a certain degree of deviation was observed in on-orbit calibration. To accurately characterize the on-orbit radiation properties of thermal infrared remote sensing payloads, an absolute radiometric calibration campaign was carried out at the Ulansuhai Nur and Baotou calibration sites in Inner Mongolia in July 2022. This paper outlines the processes of onboard calibration and vicarious calibration for the ZY1-02E satellite, comparing the outcomes of onboard calibration with those of vicarious calibration. The onboard calibration method involved internal calibration, while the vicarious calibration method utilized an on-orbit absolute radiometric calibration technique based on various natural features that were not constrained by satellite–Earth spectrum matching requirements. Calibration coefficients were acquired, and the absolute radiometric calibration results of on-orbit vicarious and onboard calibration were compared, analyzed, and verified using the radiance computed from measured data and the reference sensor data. The accuracy of on-orbit absolute vicarious calibration was determined, and the causes for the decline in the radiation calibration accuracy on the orbiting satellite were examined. The findings revealed that the vicarious calibration results exhibited a lower percentage of radiance deviation compared with the onboard calibration results, meeting the quantitative requirements of remote sensing data. These results were significantly better than those obtained from onboard blackbody calibration, offering a data foundation for devising satellite calibration plans and enhancing calibration algorithms. In the future, the developmental trend of on-orbit radiometric calibration technology will encompass high-precision and slow-attenuation onboard calibration techniques, as well as high-frequency and simplified-step vicarious calibration methods.

“…High-precision quantitative application is the characteristic of marine satellite data applications. In order to achieve the pertinence of remote sensor calibration targets and the accuracy of calibration accuracy, it is necessary to design corresponding radiation calibration devices for observation objects in different spectrum bands [3,4] . The ultimate goal of the radiometric calibration of the on-orbit infrared remote sensing detection system is to establish the functional relationship between the output signal value of the remote sensing camera and the input radiation, which is called absolute radiometric calibration [5,6] .…”

Ocean remote sensing satellites have the advantages of long-distance non-contact observation with large field of view, all-day, all-weather and real-time imaging, and have become an important means of global marine environment monitoring. The development of marine remote sensing in my country is going through a leap from "following" -"running side by side" -"leading". Quantitative application is the characteristic of marine satellite data application. In order to obtain the corresponding relationship between the input radiation and output of the remote sensing camera, and use it for quantitative inversion of the radiation information of the remote sensing target, the radiation calibration of the remote sensing camera is required. In this paper, starting from the high quantitative calibration index requirements of the new generation of ocean water color and water temperature scanner payload, a set of on-board radiation calibration device is designed and developed to realize the full spectrum, full aperture and full optical path high-precision calibration of the payload. The accuracy of the on-board radiation calibration device: the black body emissivity is 0.98, the measurement and temperature control accuracy is better than 0.05K, the temperature stability is better than 0.05K/30min, and the temperature uniformity is better than 0.2K.
