IEEE Geoscience and Remote Sensing Magazine - December 2014 - 58

Original contributions focusing on all aspects of the technical development or applications of reflectometry are
welcome. Workshop topics include; science applications to
study of the oceans, land, vegetation, cryosphere and atmosphere; Theoretical modeling, signal processing, data analysis and data fusion; Instrument concepts; Ground tests and
airborne flight experiments; and New and recent satellite
mission concepts. For more information, please visit http://
www.gnssr2015.org
In addition, an invited session, sponsored by this working
group, "Innovative approaches to GNSS+R: Instrumentation and Techniques," will be held at IGARSS 2015 in Milan,
Italy. This session will consist of a diversity of papers ranging
from the recent progress of ongoing satellite missions to new
reflectometry concepts in the early research stage. A tutorial
on GNSS-R is also provided in this issue [18].
