Abstract: The atmosphere-ocean remote sensing technology of fully mining Global Navigation Satellite Systems (GNSS) signal resources has always been a research hotspot. With the construction and development of GNSS, a series of novel technologies and methods to obtain the parameters of atmospheric and oceanic environment by GNSS delayed signals, reflected signals, occultation signals and polarimetric signals have appeared successively. In this paper, the principles of GNSS delay (GNSS-D), GNSS reflectometry (GNSS-R), GNSS radio-occultation (GNSS-RO) and GNSS Polarimetric radio-occultation (GNSS-PRO) technologies are respectively summarized on the basis of reviewing the general situation of GNSS atmosphere-ocean remote sensing technology. The progress of their research are also illustrated comprehensively and systematically, especially the mechanism, advantages and status of emerging GNSS-PRO technology. Finally, the development prospect of this field is discussed. The breakthrough and development of related technologies will play an increasingly important role in the earth science fields such as meteorology, hydrology, ocean, land and space environment.
