DEPARTMENT OF TRANSPORTATION

Type Approval of Differential Global Positioning System (DGPS) 
Ground Stations Request for Industry Input

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Federal Aviation Administration requests information and 
assistance in exploring various methods and criteria for evaluation and 
approval of commercially developed ground facilities designed to 
provide local area augmentation to the Global Positioning System (GPS) 
by the production and delivery of differential corrections and 
integrity messages. The FAA will host a meeting of interested parties 
to provide a forum for information exchange that will assist the agency 
in evaluating the technical merits, efficiency, and cost effectiveness 
of the alternative methods under consideration. In addition, interested 
parties are invited to propose other methods or criteria, not 
identified in this notice but worthy of consideration, that may improve 
or expedite the evaluation and approval process. The methods identified 
thus far for consideration by the FAA are:

Mathematical modeling and predictive analysis
Evironmental exposure testing
Bench testing
Operational testing
Spurious and harmonic radio frequency emission and sensitivity testing
Software audit and validation
Flight testing

    In addition to information on these or other testing methods, 
comments on their relative merit and benefits are welcome.

DATES: The meeting will be held on February 7-8, 1995.

LOCATION: The site of the meeting will be: The Hotel Sofitel, 425 N. 
Sam Houston Parkway East, Houston, Texas 77060, (713) 445-9000.
    Those persons staying at the hotel must make reservations not later 
than January 26. Reservations should be requested as the type-
acceptance industry meeting group.

ADDRESSES: To insure that adequate facilities are available, 
individuals or organizations that will attend are requested to notify 
the FAA of their intention to attend. Responses should be mailed to: 
Federal Aviation administration, Office of the Associate Administrator 
for Air Traffic Services, Attn: Airway Facilities Advanced Technologies 
Implementation Staff, ALM-6, 800 Independence Avenue, SW., Washington, 
DC 20591.

FOR FURTHER INFORMATION CONTACT:
William Dixon, Manager, Advanced Technologies Implementation Staff, 
ALM-6, Airway Facilities Requirements and Life Cycle Management, 800 
Independence Avenue SW., Washington, DC 20591; telephone 202-267-9147.

SUPPLEMENTARY INFORMATION: The evaluation and approval of DGPS ground 
facilities is being conducted to support early implementation of 
Special Category I (SCAT-I) approaches. These efforts are based upon 
the recommendations of RTCA Special Committee 159, as documented in the 
Minimum Aviation System Performance Standards DGNSS Instrument Approach 
System: Special Category I (SCAT-I), DO-217, and the guidance provided 
by FAA Order 8400.11, IFR Approval for Differential Global Positioning 
System (DGPS) Special Category I Instrument Approaches Using Private 
Ground Facilities.

    Issued in Washington, DC on January 6, 1995.
Joaquin Archilla,
Director of Airway Facilities.
