DORIS Data Analysis
Doppler Orbithography and Radiopositioning Integrated by Satellite (DORIS) is a microwave geodetic observation technique that provides continuous tracking of near-Earth satellites. The DORIS system is a strong geodetic pillar for precise orbit determination (POD) as well as for the computation of coordinates of DORIS stations (microwave beacons, see Figure) in geodetic reference frames.
Since 2018, DGFI-TUM is an official Associated Analysis Center (AAC) of the International DORIS Service (IDS). In this framework, DGFI-TUM regularly analyzes the DORIS observations of various altimetry satellites. Furthermore, DORIS data analysis is an important task in the context of DGFI-TUM's activities in the realization of the International Terrestrial Reference System (ITRS) in its role as an ITRS Combination Center. DORIS data analysis at DGFI-TUM is based on the DGFI Orbit and Geodetic parameter estimation Software (DOGS) that has been enhanced by DORIS analysis capabilities over the past years.
