Supporting Information for Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Data and Products from NASA CDDIS
Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Data (multi-day files) from the NASA Crustal Dynamics Data Information System (CDDIS). 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 CDDIS website at https://cddis.nasa.gov/Data_and_Derived_Products/DORIS/DORIS_data_and_product_archive.html.

Purpose
The DORIS system was developed to provide precise orbit determination and high accuracy location of ground beacons for point positioning. In addition to POD applications some of the scientific uses of DORIS data include realization of global accessibility to and the improvement of the terrestrial reference frame and monitoring deformations of the solid Earth, crustal deformation of tide gauges, and variations in the hydrosphere (sea level, ice-sheets, etc.). -
