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!ll..S 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.
