Altimetry is a satellite radar measurement which measures the distance between the satellite and the ocean surface to the nearest centimetre. The topography of the ocean surface and geostrophic currents can thus be deduced. Satellitealtimetry uses the time taken by a radar beam to make a satellite-surface round-trip, associated with a precise location of the satellite, to collect these measurements.
