Dual constellation GBAS for flexible
CAT III approach and landing applications
Summary and Outlook
January 2012 | T. Feuerle | Galileo Application Congress Prague 2012 | Seite 3
Motivation / Background: precision GNSS landing applications
Space Based Augmentation System (SBAS)
e.g. EGNOS for LPV in Europe, WAAS in CONUS
Ground Based Augmentation System (GBAS)
GPS-Stand alone (GAST C equals CAT I)
GPS with augmentation (GAST D equals CAT III)
Dual constellation GPS (GAST F equals CAT III)
Worldwide ongoing research and development for
GBAS with different kinds of installations
Advantage: GBAS and SBAS can be used for
straight-in and flexible approach procedures with one
navigation system for all phases of flight

Motivation / Background: examples of roadmaps
FAA
2.746 published LPV approaches in the US
(December 2011, www.faa.gov)
Commitment towards GBAS usage
EUROCONTROL
6 published LPV approaches in Europe
(December 2011, http://www.essp-sas.eu)
Commitment towards GBAS usage
e.g. worldwide first GBAS approach published for public usage
in Bremen (Germany)
Implementation roadmap dependent on strategies of countries

The aviationGATE has been built by the Institute of Flight Guidance (IFF)
at Technische Universitaet Braunschweig as part of the project
“UniTaS IV” founded by the Bundesministerium für Wirtschaft und
Technologie (BMWi), administered by the Agency of Astronautics of the DLR

Current Research Activities at TU Braunschweig
3 approaches
one „Haneda“ approach
two „Kansai“ approaches
approaches have been
flown with continuous
descent, but without
online guidance

Conclusions and Outlook
Braunschweig offers a unique research and test environment for GBAS approach
procedure design and testing, especially for dual-constellation (GPS/Galileo) applications
Curved and segmented approach procedures have been shown and validated with
research and commercial aircraft
Even with high requirements for GAST-D approaches these flexible approach procedures
will be possible
Continuous work will be done at Research Airport Braunschweig by University and DLR
