Global Navigation Satellite System (GNSS) Projects

GNSS

Ohio University has a rich history in the research and development of position, navigation, and timing systems utilizing the Global Positioning System (GPS).  Research has concentrated on:

• Precision Landing Systems
• Attitude based systems
• Software defined radio (SDR) architectures
• Anti-jam antenna arrays
• High performance signal monitoring
• Differential GPS and RTK (real-time kinematic) systems
• Sensor fusion for remote sensing and autonomous PNT
• Satellite and CubeSat systems.

Ground-Based Augmentation Systems” (GBAS)

• Implementation process
  • Develop operational requirements
  • Formulate candidate system architectures
  • Specify minimum performance in terms of system architecture specific parameters
  • Generate performance verification procedures
• Includes the development of flight inspection criteria for the associated instrument procedure
• Criteria development process
  • Consider test/qualification activities accomplished prior to flight inspection (inspection ≠ design approval)
  • Assess site-specific elements of Local-Area Augmentation System (LAAS) procedures and confirm availability of service
  • Identify objectives and parameters to be assessed
  • Generate assessment procedures and tolerances
  • Conditions required to put facility/procedure in service
  • Develop inspection criteria and procedure that facilitate effective, efficient sampling of service volume
• USDOT/FAA Notice 8200.116
  • Flight Inspection/ Validation of GBAS Precision Approach and Flight Procedures
• Newark Liberty International Airport (KEWR)
  • Honeywell SLS-4000 ground facility
  • December 8-15, 2009
  • Commissioned GLS (LAAS) approach procedures to runways 22L, 22R and 11
• Houston George Bush Intercontinental Airport (KIAH)
  • February 24 – March 4, 2012
  • Six instrument approach procedures commissioned
