Presentation GNSS 7.3 by
Hank Cabler
Co-Chairman, SOIT

2. History 1993 GPS Approved for use in multi-sensor applications (FMS)
also Phase 1 overlays
1994 GPS Approved for IFR use
Enroute
Domestic--same as other RNAV systems
Oceanic--used only with dissimilar LRNS
Terminal--SIDS & STARS
Approach--overlays & stand-alone
1995 GPS “Primary-means” approval for oceanic & remote
1999 GPS SCAT-1 approval
2001 WAAS approved for VFR

3. Current Status GPS Approaches ~3500 New RNAV approach chart
Designed to support WAAS, GPS, RNP 0.3, FMS Baro-VNAV
WAAS (SBAS) LNAV/VNAV Commissioning Scheduled in 2003
LPV - new approach concept
LAAS CAT I in 2004
LAAS CAT II & III later
RNP/RNAV standards development underway

4. GPS Docs GPS IFR AC 90-94-- GPS operational guidance
TSO C-129A--equipment standard
AC & installation standard
Oceanic & Remote
HBAT operational guidance
N equipment standard

5. New RNAV SIAPs

6. New RNAV Approach Plate
Approach and landing operations with vertical guidance (APV) - An instrument approach and landing which utilizes lateral and vertical guidance but does not meet the requirements established for precision approach and landing operations.
LPV - a new line of minima using the Wide Area Augmentation System (WAAS). This approach combines the lateral precision of a localizer with the vertical performance of APV-1. Provides significant operational benefits as compared to LNAV/VNAV approaches.
LNAV/VNAV - A vertically guided approach with a decision altitude down to 350 feet above the runway touchdown point (HAT). Requires a WAAS-certified receiver (or certain Flight Management Systems with barometric VNAV). Visibility requirements are generally one mile at airports without approach lighting systems.
LNAV - A nonprecision approach (no vertical guidance) with a minimum descent altitude (MDA) of 250 feet above obstacles along the flight path. At many airports, LNAV approaches will have lower minimums than existing VOR or NDB approaches. LNAV approaches can be conducted today with approach-certified (TSO-129) GPS receivers.
Because old definitions of ‘precision" and "non-precision" approaches don’t fit the new world of satellite navigation, FAA has developed new terms and standards for instrument approaches grouped under the general category of RNAV (area navigation). New RNAV instrument approach charts, already appearing in approach plate books, include:
LPV - NOTE: At the latest ICAO GNSS Panel meeting, the APV-1 definition was re-written to reflect these performance standards.
LNAV/VNAV - A vertically guided approach with a decision altitude down to 350 feet above the runway touchdown point (HAT). Requires a WAAS-certified receiver (or certain Flight Management Systems with barometric VNAV). Visibility requirements are generally one mile at airports without approach lighting systems.
LNAV - A "non-precision" approach (no vertical guidance) with a minimum descent altitude (MDA) of 250 feet above obstacles along the flight path. At many airports, LNAV approaches will have lower minimums than existing VOR or NDB approaches. LNAV approaches can be conducted today with approach-certified (TSO-129) GPS receivers.

7. WAAS Status WAAS Prime Contract Development Is Ahead Of Schedule
Contractor Acceptance Is Expected In Second Quarter Of FY 03
Commissioning Expected By Dec 03
WAAS Hardware Is Fielded And Software Development Completed To Provide A Signal-In-Space
Software Integrity Monitors And Safety Analyses Are Being Revised To Insure System Certification For IFR Use
WAAS Is Being Developed Using An Incremental Strategy To Provide Benefits As They Become Available
GEO Satellite Acquisition Activities Underway
System Is Broadcasting 24/7 And Is Providing A Robust And Reliable Signal-In-Space To A Variety Of Users

8. LAAS Status User Requirements: CAT I with advanced procedures ASAP!
