Influences of different orbit interpolation methods on substitution accuracy of rational polynomial coefficient model for multi-mode images from Gaofen-3 Satellite

2023
Determining the satellite orbit vector is necessary when constructing the geometric positioning model for a Synthetic Aperture Radar image from the Gaofen-3 satellite (GF-3), as it greatly impacts the geometric positioning accuracy. Therefore, it is vital to obtain accurate orbit vector data regarding the satellite imaging time.

Retrieval of Significant Wave Height in Coastal Seas of China From GaoFen-3 Satellites Based on Deep Learning

Remote Sensing
The acquisition of significant wave height (SWH) in coastal seas is significantly important to human activities. The Gaofen-3 (GF-3) satellites, comprising GF-3, GF-3B and GF-3C, are independently developed operational SAR of China, capable of providing high-precision, high-resolution, multi-polarization coastal ocean wave observations.
