Final answer:
LAAS is an outdated term for the Local Area Augmentation System, which enhances GPS precision for aircraft during landing.
Step-by-step explanation:
LAAS is an outdated term for the Local Area Augmentation System. This system is used in aviation to enhance the precision of global positioning systems (GPS) for the guidance of aircraft during approach and landing. An alternative to traditional ground-based navigation aids, the LAAS improves accuracy, integrity, availability, and continuity over the GPS standard positioning service.
