“…Atmospheric refraction is an important research branch in the field of remote sensing The atmospheric refractive index will affect remote sensing image positioning, space-based laser communication, star sensitive data processing and other applications [1][2][3][4][5] , so domestic and foreign scholars have also analyzed the factors that affect the atmospheric refractive index [6][7][8][9][10] . In reference [1], the authors studied the estimation of stellar refraction based on single band observations.…”

The theoretical model of atmospheric refractive index based on the standard atmospheric environment cannot explain the atmospheric refractive index when optical satellites detect targets. Aiming at this problem, a method for estimating the refractive index of the atmosphere based on multispectral stellar observation data is proposed. Based on optical satellites' multispectral stellar observation data, according to the principle of deflection when the stellar light passes through the atmosphere, the optical path model of the stellar light refracted by the atmosphere is established under the assumption of a layered spherical atmosphere. A method of using multispectral segment stars to measure the actual light and the iterative forward feedback of stellar theoretical light is proposed, to estimate the refractive index of each layer of the atmosphere of the layered atmosphere to different spectral segments of light.

The radio-wave refraction error caused by the troposphere and ionosphere badly affects accuracy in terms of the navigation, positioning, measurement, and control of a target; it is the main source of errors in high-accuracy measurement and control systems. The high-accuracy technology needed for radio-wave refraction error correction (mainly in the troposphere and ionosphere) has been the focus of research for a long time. At present, the correction methods used for radio-wave refraction errors have a low accuracy. For an S-band radio-wave signal, the accuracy of refraction error correction can generally only reach m-level (elevation angle of 15° and above), and thus has difficulty meeting the requirements of dm-level accuracy refraction error correction for deep-space and high-orbit targets. To improve the accuracy of radio-wave refraction error correction for deep-space and high-orbit targets, a novel correction method for tropospheric and ionospheric range error due to refraction is proposed in this study, on the basis of the measured data from a water vapor radiometer and dual-frequency Global Navigation Satellite System (GNSS). The comprehensive calibration test is conducted in combination with the Chinese Area Positioning System (CAPS) in Kunming. Results show that this method can effectively correct the range error due to refraction that is caused by the troposphere and ionosphere. For an S-band radio-wave signal, the accuracy of refraction error correction can reach dm-level accuracy (elevation angle of 15° and above), which is 50% higher than that achieved with traditional methods. This work provides an effective support system for major projects, such as lunar exploration and Mars exploration.
