interference angle VS. star tracker of Cryosat2

This data could be used to verify the graphic and text in the article: a bottom view interferometric synthetic aperture radar altimeter that can provide calibration data for star sensors.1. The raw data can be found on the ESA website earth.esa.int/eogateway/missions/cryosat/roll-campaigns download2. Only the intermediate data processing results of 1 second, waveform tracking and fitting results are provided here (the amount of data is too large) The phase can be extracted from the raw data by fitting the waveform.3.

This article demonstrates that the attitude angle of a satellite can be estimated using nadir interferometric radar with an accuracy of the order of arcseconds. The attitude angle result can be used to calibrate the star tracker in the ECEF coordinate system. Welcome to discuss: cuihaiying@mirslab.cn We particularly welcome research and discussions who wanna to verificate or validate this technology, and who want to collaborate with us about this work.
