Detection of Landslide‐Generated Tsunami by Shipborne GNSS Precise Point Positioning
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the R/V Sikuliaq, a research ship of the
