Alternative Positioning, Navigation, and Timing (APNT) Why does APNT need to be the back-up to GPS? Many NextGen Operational Improvements (OIs) depend on PNT services to enable RNAV and RNP and there is a great dependence on GPS-based PNT National Policy requires the provision of a backup in the event of a GPS interference event or outage National Policy National Security Presidential Directive-39 (NSPD-39) Homeland Security Presidential Directive-7 (HSPD-7 was superseded by PPD-21) Presidential Policy Directive (PPD)-21 The new system will maintain safety and security and preclude significant economic impact Today s APNT consists of legacy systems that will not support the NextGen OI s, provides limited function for RNAV, and no function for RNP or Trajectory Based Operations (TBO) Very High Frequency Omni-directional Range (VOR) Distance Measurement Equipment (DME) Tactical Air Navigation (TACAN) 13
APNT What options are being considered for APNT? The FAA s APNT Team is investigating three alternatives: Enhanced Distance Measuring Equipment (DME) Network Wide Area Multi- lateration (WAM) Pseudolites Back Last Slide APNT 8/8 Home Wide Area Multi- Lateration (WAM) Enhanced DME Pseudolites 14
