- Contexto
- To improve the accuracy, integrity and availability of GPS signals, the FAA is developing a satellite-based Wide Area Augmentation System (WAAS) and a ground-based Local Area Augmentation System (LAAS). The LAAS will utilize emerging technologies such as pseudolites (or pseudo-satellites) in the U.S. and elsewhere to extend GPS capabilities where and when needed.
- Coast Guard DGPS ground stations employ two GPS receiver/antenna pairs. The “additional” receiver/ antenna pair (termed the integrity monitor) provide a real-time continuous check on the validity of the differential corrections generated by the “basic” receiver/antenna pair (termed the reference station). DGPS ground station architectures being investigated for the FAA Local Area Augmentation System (LAAS) program employ between 2 and 4 receiver/antenna pairs to verify the corrections sent to the aircraft. No requirement for redundant ground station equipment is recommended for DGPS-based TSPI systems used in noise certification tests.
- Local area augmentation system (LAAS): A LAAS ground station provides D-GNSS corrections. These corrections will be available on the LAN through the data link manager for various systems to up-link them to aircraft and vehicles.
