Scientific cooperation

The institutes cooperating in the ADVANTAGE project at DLR (Prof. Günther, Prof. Braxmaier) and GFZ (Prof. Schuh) epitomize the systemic, technological and scientific expertise for the design, development and exploitation of future GNSS infrastructures.

The DLR Institute of Communications and Navigation in Oberpfaffenhofen-Wessling, directed by Prof. Christoph Gunther, works on the conception and analysis of communication and navigation systems involving satellites and designed for applications in aeronautics, transport and security. The institute’s activities range from fundamental research to technology demonstrations, aiming at pushing the boundaries of technology through fundamental research and in-house realization of prototypes. The institute’s activities in the ADVANTAGE project relate to system architecture design, implementation and analysis of clock ensembles, design and realization of optical links.

The DLR Institute of Space Systems, Department System Enabling Technologies, lead by Prof. Braxmaier, investigates key technologies for current and future space missions in science and Earth observation. One focal activity of the department is optical metrology. Specifically, the department focuses on assembling and integrating technologies for future operations of optical instruments in space. These include the design, implementation and verification of highly stable optical clocks and laser sensors for measuring distance and line-of-sights between distant satellites. In the context of  ADVANTAGE, the institute designs, develops and builds optical references, e.g. laser-stabilized cavities, iodine-based optical clocks, and cutting-edge hybrid concepts

The Department 1 “Geodesy” at the Helmholtz Centre Potsdam – GFZ German Research Centre for Geoscience, directed by Prof. Schuh, focuses on precisely measuring the shape and rotation of the Earth, its orientation in space, its surface, and its gravitational field, through the analyses and interpretation of data from various national and international satellite missions. Among its activities, the department proposes new Earth science applications for GNSS signals and contributes to the development of the current and future European satellite navigation systems. In the framework of ADVANTAGE, the department analyzes the Orbit Determination and Time Synchronization (ODTS) aspects and studies the impact of the proposed architecture on the geodetic sciences (e.g. geodetic reference systems, gravity field sensing, reflectometry, ionosphere plasma density and water vapor sensing).



Close ties exist to industries including TESAT, OHB, Airbus, Timetech and to institutions such as the EU Commission, the European GNSS Agency (GSA), the European Space Agency (ESA), the Inter-Union Commission on Geodynamics (ICG), the International Earth Rotation and Reference Systems Service (IERS) and others, which ensures that the new concepts and technologies developed in this project are considered for future generation navigation systems.

The project partners cooperate with all major national, European and international groups working in the areas relevant to ADVANTAGE. At the national level these include Prof. Riehle at the PTB in Braunschweig, Prof. Lämmerzahl at ZARM and University of Bremen, Prof. Hugentobler at TU München and Prof. Ertmer at Leibnitz University Hannover. Dissemination is an important aspect of ADVANTAGE; the project addresses the promotion of early career and, in particular, of female scientists.
