REALITY. RPAS EGNOS adoption and liaison with navigation integrity
The goal of REALITY is to promote the use of EGNOS for safe drone operations, in the short term and in the context of the EU drone operations vision, the U-Space. For this, REALITY will map non-recreational drone application-specific requirements into navigation performance and safety requirements –i.e., into accuracy, availability, continuity & integrity– and analyse to what extent EGNOS-based drone navigation systems meet them.
REALITY is motivated by the urgent need to respond, from an EGNSS perspective, to the challenge of safely integrating hundreds of thousands of non-recreational drones in EU airspace, flying at the so-called Very Low Level (VLL) altitude –500 ft above ground-, and at same time, by the challenge of fully leveraging current EGNOS (specifically, its integrity service) for the specific RPAS needs. As seen in preliminary studies [Molina-2012], civil aviation standards e.g. APV-I are clearly too conservative, non-protective for RPAS VLL operations, yet EGNOS has potential to be fully unleashed by adapting its integrity performance.
