EuroUSC Italia – Drone services and regulations


EU Programme: GSA – Call: GSA/EEX.0030/2015 

DURATION: 24 months | June 2016 – July 2018|

STATUS: Closed




REAL (RPAS EGNOS ASSITED LANDINGS) aims to develop and implement on RPAS an EGNOS-based navigation and surveillance sensor. The high level of integrity and accuracy achieved through EGNOS allows remote pilots to improve navigation and landing precision.

One of the purposes of this study was to highlight the benefits on safety provided by the use of EGNOS. These benefits are two-fold:

Enhanced GPS health and accuracy which reduces the effects of GPS deterioration and, on the other hand, improves robustness of geofencing protection volumes.

Higher landing and navigation precision which improves safety especially for BVLOS operations (where human error could be relevant due to lack of direct visual contact between remote pilot and the aircraft).

REAL project will target four main objectives:
to develop and integrate an EGNOS navigation and surveillance sensor in two different RPAS (one per scenario) in direct support to the navigation function down to a height from where landing can be performed using other devices. Position computed by the EGNOS sensor will also support the surveillance functions (i.e. ADS-B), allowing remote pilot to maintain awareness of the overall operational situation;
develop a concept of operations, endorsed by a safety assessment, for the approval of operations, considering the national regulations and planned European roadmap;
perform flight tests for validating the navigation and surveillance functions as in support to a safety assessment towards the future approval of operations; and
adapt existing flight procedure design criteria by considering RPAS dynamic performance as well as the operational environment for each scenario, assuming that, being no humans on board, a crash of the RPAS is not a catastrophe in itself.


The task assigned to EuroUSC Italia was to perform a safety assessment for UAS operations in BVLOS (Beyond Visual Line of Sight) in two different scenarios defined in the CONOPS:

  • power line inspections in Finland
  • a firefighting mission in Spain both at VLL (Very Low Level).

The safety assessment was carried out through SORA (Specific Operations Risk Assessment) methodology. This methodology allowed to determine the general risk level of such operations and identify “ad hoc” safety mitigations to be implemented on the RPAS employed in the real scenarios.
