Summary

Description The accurate determination of the ocean height is made by first characterizing the precise height of the spacecraft above the center of the Earth. This is achieved through a technique called "precise orbit determination," of which satellite-tracking information is the most important ingredient.The second component of the ocean height measurement is the range from TOPEX/Poseidon to the ocean surface. TOPEX/Poseidon carried two radar altimeters for providing this information. To take a measurement, an onboard altimeter bounces microwave pulses off the ocean surface and measures the time it takes the pulses to return to the spacecraft.
