Towards An Ocean Altimetry Product Using Cygnss

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents recent work being done to produce a new GNSS Reflectometry (GNSS-R) ocean altimetry product using data from NASA’s CYGNSS Mission, a constellation of 8 small satellites that measure reflected GPS signals off of the surface of the ocean.

CYGNSS Observations of Ocean Winds and Waves

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The cyclone global navigation satellite system (CYGNSS), launched on December 15, 2016, represents the first dedicated GNSS-R satellite mission specifically designed to retrieve ocean surface wind speeds in the Tropical Cyclone (TC) environment [1]. CYGNSS uses a constellation of eight microsatellite observatories that can receive both the direct and ...

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.

Investigations into CYGNSS-Based Soil Moisture Retrieval Algorithms

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
NASA’s Cyclone Global Navigation Satellite System (CYGNSS) receives the forward scattered L-band GNSS signals between ±37° latitudes. The received signals over land are previously shown to be highly sensitive to surface soil moisture (SM). Assuming coherent reflections over land, the CYGNSS bistatic radars can provide a spatial resolution of around 7 ×

The nasa cygnss mission: Overview and status update

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The NASA Earth Venture Cyclone Global Navigation Satellite System (CYGNSS) is a constellation of eight microsatellite observatories that was launched into a low (35°) inclination, low Earth orbit on 15 December 2016. Each observatory carries a 4-channel GNSS-R bistatic radar receiver.
