In relation with the voice service, the project has demonstrated its potential to be used in remote areas, as means of delegation/contingency and as a back-up frequency. Voice radio communication sessions were stablished in all the tests performed using the VOICE platform equipment. Voice radio communications was successfully exchanged between ANSPs in different FIR regions, ASA and ENAIRE and then transmitted using the HAPS equipment.
Controllers and flight crew indicated that the audio quality was satisfactory in the test performed.
In relation to the data service, Data communication sessions were established, maintained, and closed in all the tests performed using the VOICE platform equipment. The feasibility of space-based VHF data service in laboratory conditions include use of the Doppler pre-compensation feature.
The data communication has been established between the avionics of operating aircraft and a simulated ground end system, for both FANS and ATN, enabling the exchange of CPDLC messages from the controller to the pilot and vice versa.
In relation to the ADS-B service, the service was fully integrated among all the platform segments: air, space and ground. The service was as well integrated with the internal network of an ANSP, being capable of displaying information in a CWP. Technical parameters are with in standard expectations.
