The key performance parameter in Safety of Life (SoL) applications is the navigation integrity, i.e. the degree of trust one can place in the system functionality. Researchers on the DLR Navigation Integrity group investigate the robustness of the navigation solution, develop techniques to monitor threats and new methods to detect, mitigate or exclude a faulty element of the system, which could lead to an unacceptable error in the navigation solution.
Our goal is to bring GNSS onboard an Aircraft as a primary navigation system. To achieve that, we investigate error sources that can impact the user position, to design the integrity monitoring algorithms at receiver level (RAIM, AAIM), at local/global augmentation level (GBAS, SBAS) and at system level (GNSS ground monitoring stations, satellite).
Our work is subdivided into 5 major activities:
This experience mostly gained in aviation serves also other safety of life applications which are Rail, Maritime and Road.
