Automatic Dependent Surveillance – Broadcast
What are the benefits? How is it used?
● Timely and precise aircraft surveillance from GPS position information
o Air Traffic Control has more precise view of controlled airspace
o Operators can follow the paths of aircraft and ground vehicles
o With ADS-B In, pilots are aware of nearby traffic and can receive ATM services
● Requires both airborne and ground infrastructure upgrades
o Airborne Systems
ADS-B Out: GPS (Global Positioning System) Source and ADS-B
Transmitter/Transponder
ADS-B In: Multi Function
Display and ADS-B Receiver
o Ground Systems
ADS-B Ground Stations
ATC Automation Integration
Flight Following Systems
● Supports ground-based relay of complementary surveillance data

The Technology
ADS-B Technology: Link Options
● Mode-S 1090 ES (Extended Squitter) 1090 MHz (ICAO global standard)
o Builds on existing Mode-S standards with additional information (the ES)
o Required above 18,000’ in the USA and at all flight levels internationally
o Can be used in the USA below FL 180
● UAT (Universal Access Transceiver) 978 MHz (USA only)
o Cheaper installation than Mode S transponder for non-equipped aircraft
o Reduces congestion on 1090 MHZ
o Supports additional no-charge ADS-B In features (TIS, FIS, Graphical WX)
o Currently operational only in the USA. and only below FL 180
● VDL4 (VHF Data Link Mode 4) 108 – 137 MHz
o Initially embraced in the research community but not supported by the aircraft
and aerospace industries
o ICAO standards exist for VDL4; Eurocontrol performance analyses (2010)
have documented needed improvements prior to authorizing operational use

ADS-B Technology: GPS Position Sources
● Four TSOs describe GPS position source performance
● In the US, operator groups have petitioned to use existing SA-Aware
sources under waiver for some period following the 2020 mandate
● However, only SBAS/WAAS meets European/USA requirements without
use of tools like the FAA’s Service Availability Prediction Tool (SAPT)

The Applications
ADS-B In: Cockpit Display of Traffic Information (CDTI)
● Improved visual acquisition under VFR or MVFR conditions
● Situational awareness of runway occupancy
● VFR-like separation during IMC
● Enhanced VFR flight following
● Merging and spacing
● Self-separation or station keeping
● Enhanced visual approaches
● Closely spaced parallel approaches
● Reduced spacing on final approach
● Reduced aircraft separations

ADS-B In: Flight Deck Interval Management
● Provides precise inter-aircraft
spacing, enabling increases
in airspace throughput
● Increases throughput and
enhances safety
● Opportunity to apply RNAV
procedures (Optimal Profile
Descents, or OPDs)
27.04.2016 8
Graphics Source: MITRE
ADS-B In: Paired Approach
● Objective: Attain near-VMC arrival rates during IMC
● Aircraft must accurately report and
maintain their planned final
approach airspeeds (Vapp)
● Safe window position indication
and speed guidance aids pilot in
in maintaining safe approach position

ADS-B In: In Trail Procedures (ITP)
● Allows ITP-equipped aircraft to safely maneuver between flight levels /
tracks where procedural separation minima would otherwise constrain
this type of operation
● Expected benefits
o Reduced fuel burn
o Reduced emissions
o Passenger comfort
o Enhanced safety
