1. GLOBAL POSITIONING SYSTEM <1027>
The Global Positioning System (GPS) is a satellite navigation system that computes the
position of the aircraft relative to orbiting satellites. The GPS provides highly accurate
three-dimensional position, velocity and time information to the integrated avionics processor
system (IAPS).
The GPS consists of two antennas and two receivers. The antennas supply signals to their
respective receivers. The receivers process the signals and supply continuous navigation
updates to the inertial reference system (IRS) and to the flight management system (FMS).
The FMS uses the GPS and other available navigation and position sensors to provide
navigation, position information and guidance. <1212><1025><1027>
The FMS control display units provides the pilots with access to GPS data and control
settings. GPS information is displayed on the multifunctional displays. For more
information, refer to the FMS Pilot’s Guide. <1214>

1. VHF NAVIGATION
There are two VHF navigation systems installed on the aircraft and are identified as
VHF/NAV 1 and VHF/NAV 2. The systems provide the following functions:
S VHF omnidirectional range (VOR)
S Localizer/glideslope (LOC/GS)
S Marker beacon (MB)
The VHF/NAV receivers are installed in the avionics compartment and contain the logic to
control the VOR/LOC receiver, glideslope receiver and the marker beacon receiver.
Frequency tuning and mode selection is done by two radio tuning units (RTU), a single
backup tuning unit or the FMS control display unit. The radio tuning units are the primary
radio communication system radio tuning source (Refer to Chapter 05--30--01 for additional
information).
The VOR/LOC receivers operate in the following frequency ranges:
S VOR frequencies -- All even frequencies from 108.00 to 111.90 MHz and all frequencies
from 112.00 to 117.95.
S LOC frequencies -- All odd frequencies from 108.10 to 111.95 MHz
