Measuring Lake Levels with a GPS Station
Why have a GPS station in the middle of a lake? Based on a recent study published by Lucas Holden at RMIT University and Kristine Larson and the University of Colorado Boulder in the Journal of Geodesy, the reflection of the satellite signal can actually allow the station to precisely measure the changing water level around it. The researchers tested this out with ten years of data at Lake Taupō, New Zealand.
