In order to verify the application effect of surface reflectance data of hyperspectral automatic field observation equipment, the application and verification of in-orbit calibration data of Gaofen-2 (GF-2) satellite remote sensor are carried out based on the reflectance-based method. Firstly, we systematically introduces the calibration field and the working mode and performance index of various automatic observation equipment, and demonstrates the calculation method of observation data and surface reflectance data of the instrument. Then, regarding to the calibration requirements of GF-2 satellite remote sensor, the in-orbit calibration of GF-2 panchromatic and multi-spectral (PMS) remote sensor is completed using satellite atmospheric data products and synchronous observation images of GF-2 remote sensor. Finally, based on the obtained calibration coefficients, the image data of remote sensors in different time periods are verified. The application verification of two different land surfaces shows that, the overall relative deviation of satellite apparent radiance is better than 2%, which verifies the feasibility of hyperspectral equipment in the in-orbit calibration of satellite remote sensors.
