Abstract
GPS/GNSS plays a key role for navigation in autonomous vehicles. For industrial areas and harbour terminals there is a need to use autonomous or remotely controlled vehicles, for more efficient and safe operation and transport among containers and assets. Such industrial and harbour areas can be complex and confusing for untrained personell and external lorry drivers, who are usually unfamiliar with the structure and floor plan of container stacks, walls of boxed materials and building compounds. These container stacks and other structures reduce overall visibility for a human operator, making visual navigation more difficult. When drivers are confused they take a long time and use more fuel before arriving at the intended location for loading and unloading of bulk goods. Autonomous vehicles can be pre-programmed with a safe and efficient trajectory. In order to navigate properly in any terrain, autonomous vehicles require a redundant navigation system, usually consisting of GNSS (Global Navigation Satellite Systems) and INS (Inertial Navigation System) and additional sensors. One disadvantage is that the GPS / GNSS environment can be and will be degraded in a complex area with a lot of metal structures and possibly jamming signals. Thus it is important to check and monitor the quality of the signal environment for smooth continuous operation of all vehicles on the ground. In this paper, we present a novel Interference Detection and Monitoring System, GIDAS, by OHB-Digital, capable of detecting and monitoring GPS/GNSS signal jamming and spoofing, 24/7 and capable of analysing and classifying the interferer types. In addition GIDAS will store snapshots of the interference signals and alert the operator of the harbour / industrial area. GIDAS allows localization of the interference source and detailed analysis in post-processing.
