Nordisk konsept for CAT III/Autoland basert på GBAS/Nordic concept for CAT III/Autoland based on GBAS

Alternative title: null

Awarded: NOK 4.6 mill.

This project aims at developing a Ground Based Augmentation System (GBAS) for landing aircrafts based on satellite navigation signals. The main task is to develop and validate monitoring algorithms for fault detection in order to meet safety requirements. In northern regions, several natural phenomena may impact the GBAS performance, such as ionospheric turbulence, difficult weather conditions or topographical challenges. Certification and industrialisation of GBAS may give the following advantages: - shorter approach paths, hence reduced fuel needs and CO2 emissions. The flexibility may also be used to avoid densely populated areas to reduce the noise pollution. - increased capacity will reduce the operational costs for the airports, and a reduced need for additional space for more runways on airports. Higher capacity may also reduce the waiting time in holding positions, improving punctuality for the airline companies, and again reduce the CO2 emissions. Since the start of the project in 2013/2014, a GBAS prototype ground station has been installed at Oslo airport, Gardermoen. This station is now in operation, in the sense that we are collecting and treating GPS signals, and that we are able to send correction messages on air in test periods, and for test puposes. We have measured the VHF signal strength along both runways at OSL, and the results show that we are within the limits required in the standard, even at the south west runway end which is located behind the terminal when seen from the GBAS installation. The project has prepared for access to the GBAS station from the air control centre in Røyken, and the signal has been verified to be ready for test landings. The project finishes by the end of 2017 in this condition, and all involved parties are satusfied with the status and the outcome of the project.

Prosjektet omhandler utvikling av et satellittbasert landingssystem for fly, et såkalt Ground Based Augmentation System (GBAS). Hovedfokus er utvikling og validering av monitoralgoritmer for deteksjon av signalfeil, for å ivareta sikkerheten for flypassas jerer. En del faktorer som for eksempel ionosfæreforstyrrelser, værforhold og terrengforhold kan begrense anvendeligheten av GBAS i Nordområdene. Sertifisering og industrialisering av en GBAS bakekstasjon kan gi: - Kortere innflygningstraseer som vil gi lavere drivstofforbruk og redusere CO2-utslipp. Fleksibiliteten kan også brukes til å legge innflygninger unna tettbygde strøk for å redusere støybelastning. - Økt kapasitet gir lavere driftskostnader for flyplassoperatør samt at det beslaglegges mindre arealer til flyplasser med høyt kapasitetsbehov (f.eks. Gardermoen). Høyere kapasitet vil også gi mindre ventetider i holdingposisjoner som gir lavere drivstofforbruk og økt regularitet for flyselskapene, samt lavere CO2-utslipp. This project aims at dev eloping a Ground Based Aumentation System (GBAS) for landing aircrafts based on satellite navigation signals.
