GPS buoys



  • Topcon GB1000 GPS Receiver as rover
  • Trimble 4000SE GPS Receiver as base station
  • Buoy body constructed by Behrenswerft in Hamburg




  • The GPS buoys are used as a differential GPS, whereas the data of the rover (GPS buoy) will be corrected with the data of the fixed positioned base station.
  • We use this system to estimate the water level and the flow direction in the river and floodplain.
