The use of GPS buoys in the determination of oceanic variables


GPS observables taken from light-weight GPS buoys more than 80 km from the GPS reference stations have been analysed using different noise models in the parameter estimation process. The time series solution of the GPS buoy positioning have been used to extract values of oceanic variables (sea level, tides and waves) and tropospheric information. These variables are compared with data from models and with measurements from a meteorological buoy.
