Capacity Study of Two Potential Alternative Position Navigation and Timing (APNT) Technologies for Aviation
نویسنده
چکیده
The Federal Aviation Administration (FAA) is seeking to develop alternative position navigation and timing (APNT) systems in order to minimize the impact of a degradation of the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). The developed APNT system needs to have capabilities beyond those provided by currently existing FAA ground based navigation aids are needed. Ideally, the APNT system will be based on existing or soon-to-be existing FAA systems and infrastructure. Three promising technologies currently being investigated: 1) an improved distance measuring equipment (DME) infrastructure, 2) passive multilateration (MLAT), and 3) ground based “pseudolites”.
