The DORIS system was primarily designed for the precise orbit computation required for observing the oceans by altimetry.

The Diode navigator enables to provide the precise satellite position on its orbit in real time.

DORIS unique network of ground stations and its highly accurate positioning capability have also proven greatly valuable for geodesy and geophysics applications.
It contributes to the observation and determination of variables that characterize the properties of Earth, whether geodetic, geophysical or atmospheric.

Here is a list of the variables that the system can observe and that have been published since the 2000s.
