Automatic Dependent Surveillance – ADS-B (out)

  • An innovative and proven surveillance concept through ground based stations
  • Significant development in replacing or augmenting radar surveillance
  • Upcoming transponder mandate for all aircraft in Europe and US
  • Almost all new aircraft by default are ADS_B equipped

A quantum leap in aircraft surveillance — except…

Significant Gaps in Surveillance Coverage Remain

Why is Surveillance Coverage so Limited?

  • Radars are expensive for low density airspace
  • Radar and ground based ADS-B stations can be challenging to install in

remote areas with high costs of maintenance and communications

  • Limited ability to install facilities in the ocean or vast remote locations
  • A majority of the world’s airspace is uncovered by any real time surveillance

11/11/2014 4

Global terrestrial surveillance is simply not feasible

SLIDE 5

ADS-C is an Alternative, But Has Limitations

  • ADS-C tracking is not comparable to ADS-B surveillance
  • Slower ADS-C update rates results in higher separation (mins vs. sec)
  • Barrier to entry: ADS-C requires costly installation and subscriptions
  • Multiple providers require individualized equipage on aircraft
  • Several commercial aircraft types can’t be retrofitted
  • Almost no coverage over polar regions for certain providers
  • No service is provided to unequipped aircraft

11/11/2014 5

ADS-C can only support 30 nm separation at significant cost to airlines

Aireon proving to be a robust surveillance system

  • Aireon System performance testing validates ability to support both low oceanic and

terrestrial separation standards

  • High availability design uses system redundancy and cross-linked communications

backbone – 99.9% availability to the ICAO GOLD Standard

  • Flexible design functions in the presence of high interference environments from other

1090 MHz emitters (radars, Mode-S, ATCRBS, etc) as well as equatorial low density environments

  • System supports 125W ADS-B transponders (almost all commercial aircraft are

equipped with 200W or higher)

  • Built to accommodate all existing and future ADS-B standards
  • Capacity to handle future traffic growth

Aircraft Locating and Emergency Response Tracking Aireon ALERT

  • MH370 highlighted a global need for better and more accurate

surveillance of aircraft, especially in remote and oceanic locations, is obvious

  • Aireon is deploying a global space-based ADS-B surveillance

capability and will have global visibility of all ADS-B equipped aircraft in real-time in 2017

  • Aireon will provide a global emergency tracking service to

ANSPs and Search & Rescue authorities to provide the aviation community with the ability to query the location and last flight track of any ADS-B Out equipped aircraft

  • Aireon ALERT will be provided as a free public service, without

any new equipment or investment from the airlines or ANSPs

Aireon ALERT Service – How will it work?

  • The Aireon ALERT service will be

provided through a 24/7 call center to make data available soon after communication is lost with the aircraft

  • Organizations will register in

advance with the response center, and when information is requested it will authenticate the organization and then release the information

  • The Aireon ALERT service will be

able to provide the current or last known location and flight track of the aircraft based on the ICAO address

  • f the aircraft
