1. 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, VOR/ILS
receiver, VHF COMM antenna and a VHF Communications
Transceiver. The primary fundion
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 fundion 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.
2. 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-OME, TACAN, NOB, 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
9149 and
AC 120-33.
• The system meets RNP5
airspace (BRNAV) requirements of AC
90-96 and in accordance with AC 20-138a, and
JAA AMJ 20X2
Leaflet 2 Revision 1, provided it is receiving usable navigation
information from the GPS receiver.
• The Garmin International GNS 530 System has been shown to
meet the requirements listed in AC 90-100A U.S Terminal and
Enroute Area Navigation (RNAV) Operations (reference Garmin
Type2 LOA).
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.
