Polarimetric GNSS-R Sea Level Monitoring Using I/Q Interference Patterns at Different Antenna Configurations and Carrier Frequencies

Sea state monitoring using coastal GNSS - R

We report on a coastal experiment to study GPS L1 reflections. The campaign was carried out at the Barcelona Port breaker and dedicated to the development of sea-state retrieval algorithms. An experimental system built for this purpose collected and processed GPS data to automatically generate a times series of the interferometric complex field (ICF). The ICF was analyzed off line and compared ...

Sea Level Monitoring Using a Gnss-based Tide Gauge

A continuous monitoring of sea level changes is important for human society since more than 50% of the world’s population live within 60 km of the coast. Sea level is traditionally observed with tide gauges that give measurements relative to the Earth’s crust. To improve the understanding of sea level changes it is necessary to perform measurements with respect to the Earth’s center of gravity....

GNSS Spoofing Detection using Two-Antenna Differential Carrier Phase

A method is developed to detect GNSS spoofing by processing beat carrier-phase measurements from a pair of antennas in a CDGPS-type calculation. This system Copyright © 2014 by Mark L.

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...
