In-orbit Calibration and Validation of HY-2B Altimeter Using an Improved Transponder
2021
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
HY-2B (Haiyang) is the follow-on mission to HY-2A, the Chinese first sea satellite for oceanography, launched in Oct 2018. The main payloads onboard are similar to HY-2A. For the altimeter, an in-orbit calibration mode was designed to achieve higher calibration precision. An improved transponder was built and deployed for the calibration campaign. The purpose of the paper is to describe the in-orbit calibration and validation of HY-2B altimeter based on an improved transponder. A signal-rebuilt
