This paper presents new efficient guidance algorithms allowing Unmanned Aircraft Systems (UAS) to avoid a variety of Global Navigation Satellite System (GNSS) continuity and integrity performance threats detected by an Aircraft Based Augmentation System (ABAS). In particular, the UAS guidance problem is formulated as an optimal control-based Multi-Objective Trajectory Optimization (MOTO) problem subject...
In this paper, trajectory optimisation algorithms developed specifically for the Global Navigation satellite System (GNSS) Avionics-Based Integrity Augmentation (ABIA) system are presented. The ABIA system is designed to increase the levels of integrity and accuracy (as well as continuity in multi-sensor data fusion architectures) of GNSS in a variety of mission- and safety-critical aviation applications...
Unmanned Aircraft System (UAS) navigation in urban environments using Global Navigation Satellite System (GNSS) as a primary sensor is limited in terms of accuracy and integrity due to the presence of antenna masking and signal multipath effects. In this paper, a GNSS Aircraft-Based Integrity Augmentation (ABIA) system is presented. This system relies on detailed modeling of signal propagation and...
