Assessment of the Potential of Spaceborne GNSS-R Interferometric Altimetry for Monthly Marine Gravity Anomaly

Remote Sensing
The Earth’s time-variable gravity field holds significant research and application value. However, satellite gravimetry missions such as GRACE and GRACE-FO face limitations in spatial resolution when detecting monthly gravity fields, while traditional ...

Altimetry with GNSS Bistatic Radar

, 2013
For the past two decades, Global Navigation Satellite System (GNSS) signals have been explored in terms of Earth remote sensing. Most work has been done on the Global Positioning System (GPS) signals. GNSS signals are reflected off the surface of the Earth and can be received using a left hand polarized antenna which could offer a low cost alternative ...

Lake gravity anomalies from ICESat-2 laser altimetry and geodetic radar altimetry

Advances in Space Research
In the current most accepted global geopotential model, EGM2008, there are often data gaps in the source data used to compute the model over inland water. As a result, EGM2008 may be less reliable over lakes. Satellite altimetry has the  potential to estimate gravity anomalies and update EGM2008 over lakes.
