Mission Name: Jason 2


DORIS (Determination d'Orbite et Radiopositionement Integre par Satellite) helps in orbit propagation by measuring the satellites. Ground-based beacons transmit at two frequencies, 401.25 and 2,036.25 MHz, which are received by the satellite. The received doppler-shifted, frequencies provide the velocity of the satellite required for orbit propagation.
