Next Generation GNSS-R Instrument

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The science payload on each spacecraft in the CYGNSS constellation is a GNSS-R receiver and antennas designed to receive GPS L1 signals scattered from the Earth surface. The constellation was launched on 15 Dec 2016 and the GNSS-R instruments continue to operate successfully.

Advances in GNSS-R altimetry

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Since the nadir 1-second altimetry precision was first estimated to be of 56 cm when the PARIS concept was developed back in 1993 (it was assumed the interferometric processing of GPS P-code signals and a 4×4 m×m receiving antenna at 700 km orbital altitude) [1], many detailed analyses and experiments have been conducted leading to far more optimistic ...

The Pseudo Monostatic Point for Gnss-R

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Recently, the use of spaceborne GNSS-R for sea-target detection has been demonstrated using DDMs collected by SGR-ReSI onboard TDS-1. These DDMs are windowed around the forward scattering specular point. At this point, the sea-surface response is strongest and it is well suited for remote sensing of Earth’s oceans.

The GNSS-R Cygnss Mission: an Update

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
The CYGNSS constellation was successfully launched on 15 Dec 2016 and has been operating continuously in science data-taking mode since March 2017. Updates will be presented on the mission status, calibration and validation activities for its science data products, and recent scientific applications of the measurements.
