CRC 1464 (TerraQ)

  • Interferometric Fibre Links (CRC 1464, A05)
    The overarching goal, to establish chronometric levelling as a routine tool for geodesy, requires research and developments for high precision frequency transfer in the areas of Interferometric Fibre Links (IFLs) and Global Naviation Satellite System - Frequency Transfer (GNSS-FT). The development of fieldable IFLs equipment, ultraprecise GNSS-FT and their use for chronometric levelling, are new areas of research and development, which will open up many applications of geodetic interest. We aim to realise an island-mainland chronometric levelling campaign using IFL and GNSS-FT, and the transportable optical clocks developed in A04.

GNSS and Inertial Navigation

  • Grant from the European Regional Development Fund (ERDF) and the state of Lower Saxony
    In this project, a DAB-to-GNSS receiving module is developed that can receive and process GNSS corrections via DAB technology. It will be tested in comparison to mobile communications. The evaluation includes quantitative and qualitative investigation of the data stream and practical tests of the module in GNSS applications. The project is a cooperation with RFmondial GmbH.
