CYGNSS Mission Overview and Preflight Update

, 2016
The Cyclone Global Navigation Satellite System (CYGNSS) project, NASA\u27s first Earth Venture Mission, is on schedule to launch in late-2016. CYGNSS will implement a spaceborne earth observation system designed to collect measurements of ocean surface ...

Characterization of CYGNSS Ocean Surface Wind Speed Products

Remote Sensing
Since its launch in 2016, a number of wind speed retrieval algorithms have been developed for the NASA CYGNSS satellite observations. We assess their accuracy and precision and characterize the dependence of their performance on environmental factors. The dependence of retrieval uncertainty on the wind speed itself is considered.

MEASUREMENT MODEL OF IONOSPHERIC ELECTRON CONTENT WITH CYGNSS

, 2013
Global ionospheric imaging is currently limited by a lack of significant quantities of observations over the oceans. This deficiency of measurements arises because coverage from Global Navigation Satellite System (GNSS) remote sensing tools is typically ...
