Flight Test of Universal Access Transceiver (UAT) Transmissions to Provide Alternative Positioning Navigation and Timing (APNT)

This is particularly important because many key NextGen operational improvements are currently only supported by GPS. Additionally APNT may be useful for unmanned aerial systems (UASs) as many of these systems currently use only GPS for navigation. The APNT solution will build on existing FAA systems to provide the desired navigation capabilities. The APNT team is evaluating the Automatic Dependent Surveillance Broadcast (ADS-B) system as its offers significant possibility for navigation.
