Three months of local sea level derived from reflected GNSS signals

A Gnss-based Tide Gauge for Local Sea Level Monitoring

It is important for human society to continuously monitor the sea level, since more than 50% of the world’s population live within 60 km of the coast [1]. Moreover, global climate change is believed to result in the melting of large masses of ice in Polar Regions. This will bring freshwater into the ocean [2] and thus change the sea level [3]. The traditional way to observe sea level is with ti...

Detection of buried objects using reflected GNSS signals

The use of reflected Global Navigation Satellite System (GNSS) signals for sensing the Earth has been growing rapidly in recent years. This technique is founded on the basic principle of detecting GNSS signals after they have been reflected off the Earth's surface and using them to determine the properties of the reflecting surface remotely. This is the so-called GNSS reflectometry (GNSS-R) tec...

Sea Surface Roughness Estimation Using Signals from Multiple GNSS Satellites

Global Navigation Satellite System reflectometry (GNSS-R) has recently drawn significant attention since it can be employed in a range of applications including sea state, ocean altimetry, soil moisture measurement, and disaster (e.g. flooding, bushfire, and earthquake) monitoring. Although research on GNSS-R in the past two decades has made advances, there are no (or few) real applications of ...

Surface Reflectance Characteristics and Snow Surface Variations from GNSS Reflected Signals

Sea Altimetry and Scaterometry Using Gps Earth Reflected Signals

The Global Navigation Satellite Systems (GNSS) transmit L-band signals (see the Reference [1]). The GNSS receivers, as its main objective, measure the time elapsed from the transmission to the reception of L Band signals to infer the distance transmitter-receiver and to derive the three coordinates and time status of the receiver. The same signals could be recorded after its reflection on the E...
