Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) Data and Products Supporting Information from NASA CDDIS
Listed in NASA Data Portal
Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) Data (multi-day files) from the NASA Crustal Dynamics Data Information System (CDDIS).
Description
DORIS is a dual-frequency Doppler system consisting of a receiver flying aboard a satellite and a globally distributed network of ground beacons. The DORIS receiver on-board the orbiting satellite tracks the dual-frequency radio signals transmitted by the network of ground beacons and generates the DORIS data.
A measurement is made of either the Doppler shift or absolute phase as the satellite’s orbit moves over the ground-based beacon. DORIS data records contain a time-tagged range-rate measurement with associated ancillary information. The data records also contain information about any corrections that may have been applied during the processing phase, such as for the ionosphere, troposphere, and satellite center of mass, among others.

Furthermore, meteorological measurements (e.g., temperature, relative humidity, ground pressure) recorded by instruments co-located with the ground-based beacons are included with the DORIS data and can be used to determine the tropospheric correction. More information about these data is available on the Earthdata website at earthdata.nasa.gov/data/space-geodesy-techniques/doris/data-products-holdings.
