GEROS-ISS (GNSS reflectometry, radio occultation and scatterometry on board the ISS) is an ISS attached payload to.
The main focus of GEROS-ISS is the dedicated use of signals from the currently available Global Navigation Satellite Systems (GNSS) in L-band for remote sensing of the Earth with a focus to study climate change. Prime mission objectives are the determination of the altimetric sea surface height of the oceans and of the ocean surface mean square slope, which is related to sea roughness and wind speed. These geophysical parameters are derived using reflected GNSS signals (GNSS reflectometry, GNSS-R). Secondary mission goals include atmosphere/ionosphere sounding using refracted GNSS signals (radio occultation, GNSS-RO) and remote sensing of land surfaces using GNSS-R.
GEROS-ISS will be transported by a cargo craft to the International Space Station (ISS), where it will be mounted on the COF (Columbus) module.
