A new wind constellation: the Cyclone Global Navigation Satellite System (CYGNSS)

CYGNSS_AutoF

This is a new concept for scatterometry, using the reflection of GPS signals from the ocean surface to study severe storms and cyclones. CYGNSS is a constellation of eight micro-satellites that will make accurate measurements of ocean surface winds in order to better understand the life-cycle of tropical cyclones, typhoons and hurricanes. Why eight? Because the satellites do not have to carry a transmitter, but instead rely on the GPS satellites to provide the transmitted energy. This means that the individual satellites weigh about 170 kg, and that eight of them can be accommodated in one launch. This is a great idea, scheduled for launch in 2016, and I’ll write more about it in the coming weeks.

About Seelye Martin

Seelye Martin received his Ph.D. in engineering mechanics from Johns Hopkins University in 1967 then spent two years as a research associate in the Department of Meteorology at the Massachusetts Institute of Technology. In 1969 he took up a position in the School of Oceanography at the University of Washington where he is now an Emeritus Professor. Beginning in 1987, he taught courses on remote sensing of the oceans. Professor Martin has been involved with passive microwave, visible/infrared and radar ice research since 1979, and has served on a number of NASA and NOAA committees and panels involving remote sensing and high latitude processes. He has made many trips to the Arctic for research on sea ice properties and oceanography. From 2006-2008, he worked at NASA Headquarters as Program Manager for the Cryosphere, where he also served as program scientist for the ICESat-1 and ICESat-2 missions. After leaving Headquarters, from 2009 -2012, he worked in a variety of roles for the NASA high-latitude IceBridge remote sensing aircraft program. For this work, in 2012 he was awarded the NASA Exceptional Public Service Medal.
