Global Navigation Satellite System (GNSS) Projects
GNSS
51社区 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鈥 (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 鈮 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
