Lentokoneiden globaali paikannus satelliitilla etenee

[Jorma Laiho 373]

Kansainvälisessä ITUn radiotaajuuksien käyttöä koskevassa kokouksessa päästiin sopuun

ADS-B järjestelmän taajuuksien käytössä globaalissa paikannuksessa. Homma sai alkunsa tuosta MH370 katoamisesta.

Malaysia Airlines on ensimmäisenä lentoyhtiönä tehnyt sopimuksen kaikkien koneidensa reaaliaikaisesta, globaalista paikannuksesta satelliittien ja ADS-B-lähetteen avulla. Paikkatiedon toimittavat SITAONAIR, Aireon ja Flightaware. Järjestelmä pohjautuu Iridium-satelliitteihin, joita tulee olemaan yhteensä 66, ja toimintavalmiudessa ollaan vuoden 2018 aikana.

 

SITAONAIR, Aireon and FlightAware today announced that Malaysia Airlines will be the first SITAONAIR airline customer to benefit from a revolutionary flight-tracking partnership. Under the agreement, all Malaysia Airlines aircraft will have access to minute-by-minute, 100% global, flight-tracking data, delivered by SITAONAIR’s AIRCOM® FlightTracker.

 

This solution will enhance the existing SITAONAIR AIRCOM® FlightTracker by adding Aireon’s space-based Automatic Dependent Surveillance-Broadcast (ADS-B) data to the existing data from FlightAware’s multiple global sources, complementing active Air Navigation Service Provider (ANSP) Future Air Navigation System (FANS) activity data.

 

By incorporating this data, Malaysia Airlines’ aircraft operations center will receive real-time position updates of its airborne fleet globally. Aireon’s space-based ADS-B data will also resolve any existing data feed coverage gaps that remain, particularly over oceanic and remote airspace, where there is currently no surveillance.

 

No new avionics or modifications are needed for aircraft to take advantage of this service.

 

“Real-time global aircraft tracking has long been a goal of the aviation community,” said Captain Izham Ismail, Chief Operating Officer, Malaysia Airlines. “We are proud to be the first airline to adopt this solution using space-based ADS-B data as part of SITAONAIR’s AIRCOM® FlightTracker.”

 

The Aireon service will be operational in 2018, shortly after the completion of the Iridium NEXT satellite constellation. On January 14, 2017, the first ten Iridium NEXT satellites carrying the Aireon ADS-B hosted payload were successfully launched from Vandenberg Air Force Base in California on a SpaceX Falcon 9 rocket. In total, the constellation will consist of 66 operational low-earth-orbit satellites providing global coverage.

Iridium Communications on lähettänyt SpaceX:n Falcon 9-raketin avulla radalleen jo kolmannen 10 Iridium NEXT-satelliitin satsin, joten lähes puolet yhteensä tarvittavista 66 satelliitista on avaruudessa valmiina satelliittipohjaiseen, globaaliin lentokoneiden paikantamiseen. Jo tähän mennessä on järjestelmän avulla vastaanotettu yli 6 miljardia ADS-B-paikannusraporttia ja alustavat tulokset osoittavat paikkatietojen päivittyvän keskimäärin 5 sekunnin välein.

The SpaceX Falcon 9 rocket lifted off at 0537PDT on Oct. 9 from Vandenberg Air Force Base in California, carrying 10 Iridium NEXT satellites, designed and managed by Thales Alenia Space. The satellites entered low-Earth orbit approximately one hour later.

The two companies are partnered for eight launches, seven deploying 10 Iridium NEXT satellites at a time and one deploying five. Of these, 10 satellites were launched in January, followed by a further 10 in June. More than six billion ADS-B position reports have been received in just seven months and initial results show aircraft positions are updated, on average, every five seconds.

Viimeiset yhteensä 75:stä Iridium-satelliiteista on laukaistu onnistuneesti kiertoradalleen, ja kanadalaisten enemmistöomistama Aireon on lähes valmiina käynnistämään lentokoneiden lähettämien ADS-B-signaalien maailmanlaajuisen seurannan satelliiteissa olevilla vastaanottimilla ja välittämään tiedot maa-asemien kautta eteenpäin niitä tarvitseville tahoille, esim. lennonjohtoelimille. Hätätapauksien yhteydessä välitettävä seurantadata kadonneista koneista annetaan etsintäkäyttöön ilmaiseksi.

The system, which consists of ADS-B receivers carried on a constellation of low earth orbit satellites owned by Iridium, will be able to track any aircraft emitting a signal anywhere on earth. The last of 75 new satellites were successfully launched in January and Aireon, which is majority owned by Nav Canada, took over control of the ADS-B equipment last week.

“Now that we have full control over every ADS-B payload in orbit, we are just weeks away from going live with the Aireon system,” said Dennis Diekelman, Aireon’s Senior Director of Program Management. Aireon’s business plan is to sell access to the system to air traffic control service providers to replace or augment their current systems. It will go live with transatlantic and polar routes in a few weeks.  Aireon will also offer free access to its monitoring data to search and rescue organizations if aircraft go missing.
