After conducting REAL Scenario 2 validation flights the second week of April 2018, in the Hacienda de Orán, the results were analysed and among others, the maximum Flight Technical Error (FTE) was evaluated. Based on the outputs, a new navigation specification was defined (RNP 0.02) and a new RPAs instrument flight procedure was designed for ATLAS Centre for Experimental Flights, located in Villacarrillo, Jaén (Spain), where the scenario 2 final demonstrations would be conducted.

The final demonstration objective was to validate that the RPAS solution developed throughout the project, using the new RPAS procedures design criteria, covers the scenario 2 mission requirements. For this purpose, Francisco Alarcón (FADA-CATEC), José Ramón López (FADA-CATEC), Santi Vilardaga (Pildo Labs), Josep Montolio (Pildo Labs) and Daniel Viaño (Pildo Labs) moved to ATLAS the 14^th and 15^th of May 2018.

During the first day, initial short flights were conducted to ensure the proper functioning of all NSS and AirCATEC D130 equipment. After these, it was successfully conducted two RNP 0.02 procedures: a departure (RPAS RNAV ATD10) and a route (ATD10 - ATA05). Through both procedures, the RPA flown more than 6km reaching a maximum height of 135m above the ground, flying automatically commanded by NSS Box at a distance Beyond Visual Line Of Sight (BVLOS).

In parallel, it took place a technological dissemination workshop in ATLAS premises participating more than one hundred high school students from Villacarrillo (see HoraJaén, EuropaPress), The workshop aimed to make them aware of the available opportunities that technological careers can offer to young people. In this context, Francisco Alarcón joined the workshop by presenting FADA-CATEC, the tasks that they develop and provided an overview of the activities that have been performed in REAL project.

During the second day, additional flights were conducted with the aim of gathering additional data for analysis purposes. These flights were conducted at different speeds (3m/s, 6m/s, 8m/s and 12m/s) in order to analyze the guidance algorithms response and to determine the maximum FTE in each case. Additionally, a GNSS signal recorder device was installed as payload into the RPA during some flights, bringing the opportunity to replay the GNSS signals received by the RPA and test other GNSS receivers (which were not on-board the RPA) with different configurations to perform comparisons between different positioning solutions.

From the ground, it was detected a notorious improvement in the RPA navigation and guidance system and, together with other changes implemented since previous flights, it is expected to obtain better results than last time, fulfilling the RNP 0.02 navigation specifications. This assumption will be proven through the analysis of the recorded data in the following days.
