Global Navigation Satellite Systems (GNSS) in Climate Change Research: A Comprehensive Review

Global Navigation Satellite Systems (GNSSs) are playing an increasingly important role in monitoring climate change, providing precise and continuous data on processes occurring in the atmosphere, hydrosphere, cryosphere, biosphere, and lithosphere. Initially, GNSSs were used primarily for navigation and geodetic purpo...

Study on Ground-based Radar Observations for Sea Level Change Detection

Monitoring sea-level variations in tidal flats is essential for managing coastal flooding, environments, and aquaculture facilities. However, South Korea’s large tidal range limits spaceborne remote sensing observations, necessitating continuous datasets with high spatiotemporal resolution. In this study, time-series r...

Leveraging Satellite Altimetry and Gravimetry for High-Resolution Antarctic Mass Change

Satellite altimetry missions have transformed our capability to observe ice sheet surface elevation change with unprecedented spatial precision. While altimetry excels at localized surface height changes, converting height to mass requires firn air content corrections. Conversely, satellite gravimetry (GRACE/GRACE-FO)...

A payload design concept for Earth and space observations

Orion Space Solutions presents a novel integrated system that leverages Global Navigation Satellite System (GNSS) signals of opportunity for comprehensive Earth and space observations. The proposed platform combines GNSS-Radio Occultation (GNSS-RO), GNSS Reflectometry (GNSS-R), and other advanced sensing capabilities i...

Wide-swath satellite altimetry and novel subsurface observations improve predictions in a dynamic western boundary current: Resolving complex fine-scale structures.

Regional Static Gravity Field Modeling Using the GRACE-FO LRI Observations

Global static gravity models produced as spherical harmonic (SH) coefficients have a wide range of applications in geodesy, geophysics, oceanography, and satellite dynamics. It has been established that more information can be extracted from the observations using regional modeling compared to global spherical harmonic...
