4Todays Air Transportation System
- Ground-based
- Human-centric and un-automated
- Single channel voice control
- Aging Infrastructure (youngest en-route facility
43 years old)
5Next Generation Air Transportation System
(NextGen)
- Transformation and Modernization of the National
Airspace System - Goal is to
- Triple the amount of air traffic capacity
- Further enhance safety
- Strengthen Homeland Security
- Protect the Environment

7Automatic Dependent Surveillance - Broadcast
(ADS-B)
- Automatic
- Periodically transmits information with no pilot
or operator input required - Dependent
- Position and velocity vector are derived from the
Global Positioning System (GPS) - Surveillance -
- A method of determining position of aircraft,
vehicles, or other asset - Broadcast
- Transmitted information available to anyone with
the appropriate receiving equipment

12Backup Analysis Ground Rules - Minimum
Requirements
- Strategy must support ATC surveillance
application - Basic en route and terminal area services
- Support for other applications desirable, but not
required - Continuity of services must be maintained
- Must maintain at least the same level of capacity
during a GPS outage that we would have during a
radar outage today - 3 nm separations in top 40 high density
terminals - 5 nm separations in medium density terminals and
en route - Coverage volume same as CENRAP coverage top 40
terminals - Safety of operations must be maintained
- Single-aircraft avionics failures must also be
addressed - Strategy must be able to be implemented and made
operational on or before ADS-B rule compliance
date
13Backup Analysis Potential Backup Technologies
and Methods
- Surveillance
- Secondary radar
- Primary radar
- Passive multilateration
- Active multilateration
- Positioning/Navigation
- DME/DME/IRU
- DME/DME
- eLoran
- IRU only
- Satellite Navigation Only (SBAS/WAAS, L5,
Galileo) - VOR/DME, LOC/DME, MLS/RNAV
- Procedural Separation
14Backup Analysis Recommendation
- The FAA should adopt Backup Strategy 1,
Secondary Radar - Retain (reduced) secondary radar network to cover
required airspace, and use primary radar to
mitigate single-aircraft avionics failures - Requires approximately 40 terminal Secondary
Surveillance Radars (SSRs) and 150 en route SSRs
be retained beyond 2020 (compared to a total of
approximately 380 today) - No additional equipage required for aircraft
- This strategy is assessed as having the highest
performance ranking and lowest life cycle cost - The FAA should revisit this assessment prior to
committing to radar investments beyond 2020 - Changes in evaluation assumptions could
significantly affect results of this assessment - Investment decision for Strategy 1 required no
later than FY2014
15Automatic Dependent Surveillance-Broadcast
(ADS-B) Backup System
- The FAA adopted Radar as the preferred back up
system. - But current radar networks are
- Aging (new ones are up to 40 years old)
- Nearing the end of their service life
- Expensive to maintain
-
16Potential Benefits of MPAR in Civil Aviation
- MPAR may prove to be a viable, cost-efficient
backup to ADS-B. - MPAR may assist in achieving key NextGen
capabilities such as - Assimilating Weather into Decision-making
- Aircraft Trajectory-Based Operations
- Super Density Operations
17MPAR Concept
18MPAR Performance Benefits
- MPAR enables a 35 reduction in the number of
radars. - MPAR can save 1.8 billion savings in replacement
acquisition costs. - MPAR can save an additional 3 billion in life
cycle costs over 30 years
