Dependent dependent on the aircraft s on-board navigation system Surveillance used by Air Traffic Control Broadcast undirected and unsolicited

2 Overview What is ADS-B? ADS-B is an advanced surveillance technology for aviation ADS-B stands for Automatic Aircraft provide surveillance data automatically every second Dependent dependent on the aircraft s on-board navigation system Surveillance used by Air Traffic Control Broadcast undirected and unsolicited transmission Data content is aircraft ID, position, velocity supplementary data A complete ADS-B data set is broadcast approx. 1/second Majority of all international airliners are ADS-B equipped* LH > *Airservices Australia, IATA 2 ADS-B is an established air traffic surveillance standard

3 Overview Just how does ADS-B work? Uses same 1090MHz radio band as Secondary Surveillance Radar Data received at ground stations: Overlapping telegrams must be degarbled using digital signal processing ADS-B is mandatory in Australia, and will become mandatory in Europe, United States and China in Regional networks of terrestrial ADS- B receiving stations exist in most developed economies No coverage exists beyond the range of terrestrial surveillance! 3

4 Overview What is space-based ATS concept? Global Designed to take ADS-B technology to space Designed to take VHF Air band to space Expands radar-like ATC beyond the range of terrestrial surveillance Converts non-radar airspace into radar-like airspace Complementary Provides a backup to existing ATC systems Augments existing infrastructure Brings ADS-B surveillance to almost everywhere! 4

Satellite ADS-B/VHF Mission Objectives I: Surveillance and ATC Together, Sat ADS-B and Sat VHF Com are designed to allow radar-like operations in remote locations.

5 Satellite ADS-B/VHF Mission Objectives I: Surveillance and ATC Together, Sat ADS-B and Sat VHF Com are designed to allow radar-like operations in remote locations... for more efficient airspace use: reduced separation minima optimised routing optimised cruise climb... for more efficient ATC: reduced workload improved situational awareness improves existing infrastructure 5 Satisfying ICAO communication and surveillance performance requirements! There is a global need to cover non-radar airspace!

6 Satellite ADS-B Mission Objectives II: Global Flight Tracking Emergency Location Following the loss of AF447 MH370 AH5017 And others ICAO recommended mandate for global flight tracking less than 60s! 15 Minute updates = Travel distance: Cardiff London Uncertainty Area: England 1 Minute updates = Travel distance: Across Greater Cambridge Uncertainty Area: London 10 Second updates (e.g. Sat ADS-B) = Hyde Park Covent Garden Uncertainty Area: Kensington The international civil aviation organisation (ICAO) focuses on global flight tracking solutions!

10 User Requirements Constraints Keep aircraft flying with existing avionics Use 1090MHz Extended Squitter (ES) Existing VHF radios Need for additional and complementary infrastructure Independence Redundancy Safety Maintain existing interfaces Coverage of customer s service volume of responsibility Seamless transition between terrestrial and space-based ATC User needs are well understood and documented - but keep evolving! 10

11 User Requirements Design Drivers 11 Most promising business areas for ADS-B/VHF combined services are Asia Pacific (APAC) incl. Australia Major problem: difficult geography, demand outgrows capacity, political Major gains: contiguous ATC, situational awareness, cost effective Africa Major problems: difficult geography, lacking infrastructure, theft Major gains: increased surveillance, reliability, improved safety South America Major problems: difficult geography, lacking infrastructure, climate / deterioration Major gains: increased surveillance, reliability, improved safety Demand is stronger nearer the equator! 11

12 User Requirements VHF Air Band Coverage 12 Demand is expected to be strongest within 30 degrees North / South! 12

13 User Requirements VHF Air Band Coverage (traffic density) APAC has the highest growth rate, second highest density (after NAT) and reaches capacity limits 13

14 User requirements derived Mission Design Drivers 14 Most important design drivers derived from Signal-to-Noise Ration Driven by: Probability of reception, condition of worst user Drives: Antenna size vs. orbit altitude Baseline assumption: km altitude Safety case Driven by: Redundancy requirement & availability of alternate means Drives: Number of satellites in view Baseline assumption: 1 Satellite in view at all times, 2 in view most of the time, emergency fall back to HF or CPDLC for VHF and ADS-C for ADS-B Demand is stronger nearer the equator! 14

15 Interfaces: The Landscape 15 Existing Satellite Aviation Services ADS-C, ACARS, CPDLC Sat Voice E.g. Inmarsat ClassicAero & SwiftBroadband services, Iridium Future Services Aireon Gen 1 Sat ADS-B intended to become operational in 2018 TAS-D Satellite Payloads for Aviation Services Designed to complete the picture Designed to serve aircraft presently not equipped with dedicated satcom equipment Demand is stronger nearer the equator! 15

16 Satellite Air Traffic Control Services Payload The TAS Proposal Develop the next generation Satellite ADS-B and VHF communication system Aircraft surveillance data is received by satellites, downlinked and disseminated VHF voice communication is broadcast and received through satellite based transceivers Using existing ADS-B transponders and VHF com radios Jointly developed by TAS, Thales ATM and key partners Deploy and integrate the system Compatible with standard ELITE 1000 and ELITE 2000 busses Compatible with standard ATM systems Service coordinated with key partners 16 Allow the following Services Live (real time) data (continuous surveillance data streaming) Real-time voice communication (across any Flight Information Region) Emergency services, emergency alerting and last available data recovery To provide a global satellite air traffic control services solution!
