Using GPS phase observations in the kinematic mode, we are able to achieve centimeter accuracy in relative three#x2010;dimensional coordinates. This could be verified even for fast#x2010;moving sensors in aircraft, such as airborne photogrammetric cameras, at the time of exposure. Sophisticated kinematic software has been developed resolving cycle slips and carrier#x2010;phase ambiguities during motion. To determine the instantaneous sea surface, the GPS receiver is placed in a free#x2010;drifting buoy with the antenna on top. Differencing the 1#x2010;Hz observations, wave heights can be determined as well as velocity and direction of ocean (tidal) currents.
