I often get asked why use GPS/GNSS to measure tides when I can buy a tide gauge at the store. One big advantage is that this way you can simultaneously measure land motion and tides. So 🌊 people don’t have to ask, is the water going up or is the land going down?

When I retired, I started building an open source software package (see my bio for the link) that takes GPS/GNSS signals that reflect off water/ice surfaces so you could use a traditional geodetic sensor as a tide gauge. This example is from Greenland. 🌊 and 🧪❄️
