The in-flight performance of the GEOSAT radar altimeter is shown to be superior to that of Seasat by comparing noise power spectra derived from collinear tracks. Interpretation of the spectra shows that the portion of the noise contributed by the GEOSAT altimeter itself is about 3 centimeters rms. Additional noise contributed by oceanographic effects raises the total rms noise level to between 5 and 11 centimeters rms.
