The operational monitoring of modern agricultural remote sensing is closely related to the characteristics of crop phenology. It requires satellites with high revisit frequency, wide coverage, and spectral bands sensitive to the spectral reflectance of vegetation. This paper provides the development and performance of the ultra-Swath agricultural remote sensing satellite. First, it details the design, installation, alignment, and testing of the wide-field camera (WFV) in the free-form optical system. A single camera achieves a resolution of 16 m, 12-bit quantization, 8 spectral bands, and an 860 km imaging swath. On the basis of the traditional red, green, blue, and near-infrared spectral bands, two red-edge spectral bands, coastal blue, and yellow spectral bands are added, making the system particularly suitable for multi-spectral monitoring of large-scale agricultural and forestry resources. Secondly, it shows the in-orbit status of the satellite. Then, the agricultural applications of the satellite are introduced. Finally, combined with users’ requirements, the development suggestions of follow-up satellites are proposed.

摘要

The operational monitoring of modern agricultural remote sensing is closely related to the characteristics of crop phenology. It requires satellites with high revisit frequency, wide coverage, and spectral bands sensitive to the spectral reflectance of vegetation. This paper provides the development and performance of the ultra-Swath agricultural remote sensing satellite. First, it details the design, installation, alignment, and testing of the wide-field camera (WFV) in the free-form optical system. A single camera achieves a resolution of 16 m, 12-bit quantization, 8 spectral bands, and an 860 km imaging swath. On the basis of the traditional red, green, blue, and near-infrared spectral bands, two red-edge spectral bands, coastal blue, and yellow spectral bands are added, making the system particularly suitable for multi-spectral monitoring of large-scale agricultural and forestry resources. Secondly, it shows the in-orbit status of the satellite. Then, the agricultural applications of the satellite are introduced. Finally, combined with users’ requirements, the development suggestions of follow-up satellites are proposed.
