There is an increasing need for coastal sea level monitoring due to climate change. The tide gauges currently used need to be near the water, which makes them difficult to install and maintain. The Satellite Tide Gauge offers an alternative solution which can sense sea levels from a distance while being mounted on a building or any type of terrain. The system is based on the reflection of radio waves on the sea surface. It uses transmissions made by navigation satellites such as GPS, Galileo, and similar Global Navigation Satellite Systems (GNSS). The Satellite Tide Gauge is a complete system for GNSS reflectometry that includes both hardware and software.
Moreover, very low costs can be achieved by exploiting mass-market, consumer-grade GNSS parts. Users are provided with the sensor for free, which can be used on the basis of a monthly or annual subscription. The configuration proposed is also expected to open up new market scales that were simply out of reach for conventional tide gauging technologies.
