Objective
The goal of AUDITOR is the implementation of novel precise-positioning techniques based on augmentation data in custom
GNSS receivers to improve the performance of current augmentation services and reducing costs. These techniques are
already patented by the consortium and proven to offer better accuracy with faster convergence times than solutions
commercially available. More sophisticated atmospheric models will be implemented to provide better corrections of
ionospheric errors and further increase accuracy. All these advances will be integrated in a software demonstrator that will
use public data from GNSS networks to generate these correction data streams. These new receivers will enable cost-effective precision agriculture services to farmers, especially those with small and medium-sized businesses in areas of Europe.
The custom dual-frequency receiver module will follow an innovative approach by porting a GNSS software-defined receiver
to an embedded system that will integrate hardware accelerators to enable real-time operation in a low power system. The
form factor and capabilities of the resulting receiver will be comparable to those of existing professional receivers in the
market, while retaining all the advantages of software receivers: modularity, scalability, upgradability, and flexibility. Besides
providing multi-frequency multi-constellation support, this advanced receiver will allow very low level access to key internals
even at sample level, enabling the integration of other complementary techniques like interference analysis and monitoring
or authentication using remote servers for encrypted bands. The fact that the software layer will be the evolution of an existing
and successful open-source project, GNSS-SDR, will allow GNSS developers and researchers to customize the code of the
receiver to tailor it to their own applications or test their algorithms using this flexible receiver module, from reflectometry to
ultra-tight coupled GNSS/INS systems.
