Foreword to the Special Issue on GNSS Reflectometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
The papers in this special section focus on Global Navigation Satellie System reflectometry(GNSS-R) which is defined as the use of digital signals—here signals from Global Navigation Satellite Systems (GNSS)—as sources of illumination in a bistatic radar system.

An Introduction to the HydroGNSS GNSS Reflectometry Remote Sensing Mission [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
HydroGNSS (Hydrology using Global Navigation Satellite System reflections) has been selected as the second European Space Agency (ESA) Scout earth observation mission to demonstrate the capability of small satellites to deliver science. This article summarizes the case for HydroGNSS as developed during its system consolidation study.

Modified GNSS-PIR and Initial Verifications From the Perspective of Altimetry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article proposed a modified structure of global navigation satellite system (GNSS) pseudointerferometric reflectometry (GNSS-PIR). The combination of the direct and reflected signals at the front end was modified as the combination of their coherent

Remote Sensing of Forest Biomass Using GNSS Reflectometry [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
In this study, the capability of Global Navigation Satellite System Reflectometry in evaluating forest biomass from space has been investigated by using data coming from the TechDemoSat-1 (TDS-1) mission of Surrey Satellite Technology Ltd. and from the Cyclone Satellite System (CyGNSS) mission of NASA.

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...
