REPORT: VB-1611 ISSUED: JULY 12, 1995
9-104, 2 of 8 REVISED: JUNE 14, 2004
SECTION 1 - GENERAL
The GNS 530 System is a fully integrated, panel mounted instrument, which
contains a VHF Communications Transceiver, a VOR/ILS Receiver, and a Global
Positioning System (GPS) Navigation computer. The system consists of a GPS
Antenna, GPS Receiver, VHF VOR/LOC/GS Antenna, VOR/ILS Receiver, VHF
COMM Antenna and a VHF Communications Transceiver. The primary function
of the VHF Communication portion of the equipment is to facilitate
communication with Air Traffic Control. The primary function of the VOR/ILS
Receiver portion of the equipment is to receive and demodulate VOR, Localizer,
and Glide Slope signals. The primary function of the GPS portion of the system
is to acquire signals from the GPS system satellites, recover orbital data, make
range and Doppler measurements, and process this information in real- time to
obtain the user’s position, velocity, and time.
Provided the GARMIN GNS 530’s GPS receiver is receiving adequate usable
signals, it has been demonstrated capable of and has been shown to meet the
accuracy specifications for:
• VFR/IFR enroute, terminal, and non-precision instrument approach
(GPS, Loran-C, VOR, VOR-DME, TACAN, NDB, NDB- DME, RNAV)
operation within the U.S. National Airspace System in accordance with
AC 20-138.
• One of the approved sensors, for a single or dual GNS 530 installation,
for North Atlantic Minimum Navigation Performance Specification
(MNPS) Airspace in accordance with AC 91-49 and AC 120- 33.
• The system meets RNP5 airspace (BRNAV) requirements of AC 90-96
and in accordance with AC 20-138, and JAA AMJ 20X2 Leaflet 2
Revision 1, provided it is receiving usable navigation information from
the GPS receiver.
NOTE
Navigation is accomplished using the WGS-84 (NAD-83) coordinate reference
datum. Navigation data is based upon use of only the Global Positioning System
(GPS) operated by the United States of America.
