To provide satellite users with a variety of life cycle, flexible mode of in-orbit management services.

Optical Satellite Calibration and Inspection Services

Radiation calibration and MTF detection of high resolution optical remote sensing satellites by point light source array reflection.

Service Introduction

The point light source array set in the calibration field reflects the sunlight to the entrance pupil of the satellite camera, and performs on-orbit radiation calibration and MTF detection for the high-resolution optical remote sensing satellite sensor, thereby realizing the radiation performance and image quality of the optical remote sensing satellite remote sensing image. quality assessment. It can support optical remote sensing satellite sensor modulation transfer function measurement; and can support optical remote sensing satellite sensor absolute radiometric calibration.
