NASA 3D Models: OSTM/Jason-2

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: October 24, 2025 | Last Modified: 2025-04-01
OSTM/Jason-2's primary payload includes five instruments similar to those aboard Jason-1, along with three experimental instruments. Its main instrument is an altimeter that precisely measures the distance from the satellite to the ocean surface. Its radiometer measures the amount of water vapor in the atmosphere, which can distort the altimeter measurements. Three location systems combine to measure the satellite's precise position in orbit.
