The goal of the project is to develop a DAB-to-GNSS receiving module that connected with typical geodetic GNSS receivers enables the reception and processing of GNSS correction data via DAB technology. The use of this technology is examined qualitatively and quantitatively in real field applications. The focus here is on a direct comparison with correction data transfer via mobile communications, which is currently considered the standard in this area. In addition to the technical planning and implementation of the receiving module, the project includes the detailed evaluation and validation of the module to be developed in various static and especially kinematic GNSS applications.

The project is carried out in cooperation with RFmondial GmbH, whose tasks include the development of the receiving module including system design with selection of a suitable chip, circuit board design and subsequent verification of the manufactured prototypes. Furthermore, RFmondial supports IfE in setting up and implementing the concept for evaluating and validating the module as well as during practical measurements and subsequent evaluation. On the side of the IfE, the practical evaluation and validation of the receiving module and the correction data stream is divided into two parts. First, the data stream itself is examined, particularly with regard to completeness, latency and integrity. In the second part, the developed module is extensively tested in practical use, with the main focus being on the direct comparison of GNSS receivers that get the GNSS correction data via mobile communications and those that receive them using the developed DAB module.
