Ground-Based Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Satellite Orbit Product from NASA CDDIS
Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Satellite Orbit Product 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. DORIS observations from a global network can be utilized for a variety of products. Analysis Centers (ACs) of the International DORIS Service (IDS) retrieve DORIS data on a regular basis to compute various DORIS products from data generated by the DORIS beacons supporting the IDS network. These products include orbits of satellites with DORIS receivers onboard. These orbit products are available in SP1 or SP3 orbit format.

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.). - Search for granules from this collection
