WAAS Dual Frequency Operations • ‘Sunset’ of L2 P(Y) compels WAAS to utilize another signal to
maintain current service
– USG Federal Register Notice states ‘sunset’ for L2 P(Y) signal use in
December 2020
• New dual frequency L1/L5 service needed to further improve WAAS
availability and continuity

GBAS (Ground Based Augmentation System)
GNSS Overview 12 Federal Aviation
Administration May 15, 2013
FAA GBAS Program
• The FAA has indefinitely delayed plans for GBAS
acquisition
• The FAA GBAS program focuses on three task
areas: – GAST-D ICAO SARPs validation
• FAA CAT III activities focus on single frequency GPS
augmentation requirements
• Produce an commercial prototype for validation testing
– Vendor could seek NonFed approval
– Radiofrequency interference (RFI) analysis and mitigation
– Limited CAT I implementation support
• Newark NJ and Houston TX operational approval support
• Gain operational experience with GBAS

Project Houston Update • History:
– FAA SATNAV team decision to provide a GBAS at Houston yielding a city-pair for GBAS operations
– Plan included moving Memphis GBAS to Houston, development of advance procedures, and simulation testing
• This is a non-Fed GBAS installation owned by the Houston Airport System (HAS)
• Activities Completed
– Remove system from Memphis, GBAS factory refurbishment, site studies including RFI testing, installation, site acceptance testing, flight inspection, non-fed coordinator training, predictive tool training, SDA revision
• All approval and agreement documentation completed
• Operational Approval April 2013
– Operational approval for use of GBAS in Houston was awarded on April
22nd 2013 and the first flight to the use approach, United Airlines Flight
1542, landed Runway 27 the same day

GBAS International
• International Cooperation (FAA MoAs)
– Germany, Spain, Brazil, Chile, Australia,
– FAA Training : India, China
• International GBAS Working Group (IGWG)
– International Service providers (ANSPs),
Industry, OEMs, Airlines, Airports,
EUROCONTROL, FAA
– Cooperation and coordination of implementation
and development activities
• RFI, Siting, World Wide IONO, Ops concepts
– IGWG Website - flyGLS.net
– Next IGWG June 4-7, 2013 hosted by Boeing
• GBAS and SESAR
– SESAR work packages for GBAS CAT I
implementation, Single frequency CAT III, Dual
frequency CAT III and multi constellation GBAS
GNSS Overview 16 Federal Aviation

Need for Alternative Positioning,
Navigation & Timing (APNT) • NextGen is dependent on the availability of GPS-Based PNT services
and suitable alternate PNT services
– RNAV and RNP procedures for trajectory-based operations (TBO)
– Current ATC system cannot be scaled up to handle 2X traffic
– 2X traffic is more than a controller can handle using radar vectors
– Procedural separation with Conformance Monitoring will separate aircraft
performing trajectory based operations (TBO)
– Controllers intercede to provide “control by exception”
• TBO Operations may require PNT performance that exceeds
DME/DME/IRU
• GPS vulnerability to radio frequency interference (RFI) requires
mitigation
– Waiting for the source of the interference to be located and turned off is not an acceptable alternative
