Motiv<strong>at</strong>ion / Background: precision GNSS landing applic<strong>at</strong>ions<br />
Space Based Augment<strong>at</strong>ion System (SBAS)<br />
e.g. EGNOS for LPV in Europe, WAAS in CONUS<br />
Ground Based Augment<strong>at</strong>ion System (GBAS)<br />
GPS-Stand alone (GAST C equals CAT I)<br />
GPS with augment<strong>at</strong>ion (GAST D equals CAT III)<br />
Dual constell<strong>at</strong>ion GPS (GAST F equals CAT III)<br />
Worldwide ongoing research and development for<br />
GBAS with different kinds of install<strong>at</strong>ions<br />
Advantage: GBAS and SBAS can be used for<br />
straight-in and flexible approach procedures with one<br />
navig<strong>at</strong>ion system for all phases of flight<br />

3 approaches<br />
one „Haneda“ approach<br />
two „Kansai“ approaches<br />

approaches have been<br />
flown with continuous<br />
descent, but without<br />
online guidance
Conclusions and Outlook<br />
<strong>Braunschweig</strong> offers a unique research and test environment for GBAS approach<br />
procedure design and testing, especially for dual-constell<strong>at</strong>ion (GPS/Galileo) applic<strong>at</strong>ions<br />
Curved and segmented approach procedures have been shown and valid<strong>at</strong>ed with<br />
research and commercial aircraft<br />
Even with high requirements for GAST-D approaches these flexible approach procedures<br />
will be possible<br />
Continuous work will be done <strong>at</strong> <strong>Research</strong> Airport <strong>Braunschweig</strong> by University and DLR<br />
