Precise Orbit Determination is a critical part of measuring sea level rise
11/15/2020

Precise Orbit Determination (POD) is a geodetic technique that enables knowing the exact position of a satellite above a stable reference point on Earth. Determining the exact position of the satellite when an observation is acquired is crucial in measuring sea level height. As noted by Dr. Frank Lemoine, a geodesist with NASA's Space Geodesy Project and a member of NASA's Ocean Surface Topography science team, "If you don't do POD right, you're not going to get any sea level results."
