Professional Pilot, May 2017

environmental benefits for industry and research as well as for aviation Part of the test includes use of the Inmarsat I 4 F1 satellite which is the 1st to provide SBAS correction on both the L1 and L5 allocated frequencies for civil navigation Dual frequency for satellite navigation and SBAS signaling increases reliability and mitigates error for ionospheric slowing of satellite signals KASS South Korea The Korean augmentation satellite system is being developed based on the EGNOS protocol Programmed to be available in July 2020 safety of life SoL use which includes aviation is scheduled for the Incheon FIR starting October 2022 Aireon and Iridium NEXT In January 2017 Iridium Communications announced the launch of the first 10 Iridium NEXT low earth orbit communications satellites This is the 1st of 8 planned launches through 2018 to place 66 possibly 70 NEXT satellites in orbit Iridium NEXT are unique in that they have ADS B capability in the 1090 extended squitter protocol which is the ICAO worldwide standard for ADS B This creates the potential for a spacebased global surveillance system using ADS B on a satellite instead of traditional radio receiver towers on the ground Aireon redesigned the NEXT system into flexible and highly effective space grade receivers on these Iridium 2nd generation satellites This will allow for 100 global surveillance using the ADS B signal transmitted by aircraft carrying such equipment 40 PROFESSIONAL PILOT May 2017 Despite the growth of satellite based augmentation systems and several inplace navigation satellite constellations the ability to surveil and track aircraft in real time is only available over approximately 30 of the worlds airspace The tragic disappearance of Malaysia Airlines Flight 370 in March 2014 only highlighted the fact that a flight can truly be lost Aireon and Flight Aware will be able to detect aircraft positions in real time everywhere in the world with a program termed Global Beacon for aircraft equipped with ADS B Out It promises to be a cost effective easy to deploy option that transcends borders and flight information regions FIRs including polar airspace Global Beacon meets ICAO global aeronautical distress safety system GADSS standards due to its truly worldwide capability Global Beacon combines Flight Awares secure web platform and worldwide flight tracking information including origin destination flight plan route position and ETA with Aireons space based ADS B network This will provide users with a real time aircraft tracking dashboard that features configurable alerts and notifications of abnormal events Should an aircraft deviate from its intended flightpath experience severe turbulence or stop transmitting location the aircraft will automatically enter distressed status and immediately notify its operations center Envisioned primarily for air carriers Global Beacon will provide aircraft tracking capabilities starting in mid 2017 with plans to begin 1 minute interval tracking by 2018 Air navigation service providers In March of 2017 Aireon signed a memorandum of agreement MoA with Spanish air navigation service provider ENAIRE who will begin investigating the safety efficiency and environmental benefits of using spacebased ADS B for its airspace ENAIREs airspace includes the Iberian Peninsula Portugal excluded the North Atlantic Western Mediterranean Ceuta and Melilla and the Canary and Balearic archipelago Through this airspace ENAIRE manages approximately 2 million flights per year including routes over oceanic airspace such as the northern portion of the Madrid FIR and the majority of the Canary FIR Space based ADS B would for the 1st time offer ENAIRE 100 visibility of all of its airspace in real time including remote and oceanic regions This is just 1 example of the numerous other air navigation service providers who have or are considering a MoA with Aireon as an alternative to ground based surveillance equipment that is expensive to maintain For the 1st time there is now the potential for real time tracking in airspace where no ground based system is possible The fact that augmented satellite navigation is not available worldwide either through SBAS or ground based systems is offset partially by the fact that the accuracy of PBN via RNP in much of the worlds airspace does not require positioning accuracy greater than that available from non augmented satellite navigation Conclusion Satellite positioning has created possibilities never before realized In Barra Outer Hebrides Islands 2 LPV procedures assist scheduled air carrier flights to a beach runway Beach landings are not new but an instrument arrival to a beach simply exhibits the flexibility and accuracy of satellite navigation The GANP and these multiple subprograms offer a tantalizing shift in how we fly The next few years will be an interesting time for air navigation worldwide An RNAV RNP approach depiction on a Garmin avionics suite display illustrates the advantages of PBN Advances in avionics displays terrain avoidance technology and augmented GPS are providing exponential gains in situational awareness safety
