A Novel GNSS Integrity Augmentation System for Autonomous Airport Ground Operations

In recent years, the degree of vehicle automation is continuously increasing in all modes of transport. Automated Guided Transport (AGT) systems, which were conceptualised a couple of decades ago are now being realised as unmanned aircraft systems and autonomous ground/sea vehicles. Autonomous ground vehicles are an emerging tool that provide a safer, more cost-effective and sustainable alternative to traditional methods. Furthermore, they offer the capability to detect, alert and compensate for any deviations from the required system performance. In this paper, the system architecture and...

Avionics-Based GNSS Integrity Augmentation Synergies with SBAS and GBAS for Safety-Critical Aviation Applications

This paper explores the synergies between a novel Global Navigation Satellite System (GNSS) Avionics-Based Integrity Augmentation (ABIA) system and current Space and Ground Based Augmentation Systems (SBAS and GBAS). The ABIA Integrity Flag Generator (IFG) is designed to provide caution and warning integrity flags (in accordance with the specified time-to-caution and time-to-warning requirements) in all relevant flight phases. The ABIA IFG performances are assessed and compared with the SBAS and GBAS integrity flag generation capability. Simulation case studies are presented using the...
