1.1 Scope
This document will detail information required to install and use the GLU-2100 unit.
1.1 Overview
The GLU-2100 is packaged in an ARINC 600 size 3 MCU case to receive and process ILS,
GLS, VOR, MB, and GNSS signals.
GLS, VOR, MB, and GNSS signals.
The GLU-2100 is a navigation sensor with internal receivers used for enroute, terminal, and
instrument approach and landing operation.
instrument approach and landing operation.
A NAV CCA provides ILS flight path deviation guidance for precision approach and landing as
well as VOR/Marker Beacon functions. The VOR function receives, decodes, and processes
bearing information from the transmitted VOR signal, while the Marker Beacon function provides
visual and aural identification when the aircraft is over a marker beacon transmitter by
illuminating one of three indicator lamps and outputting one of three audible tones (400, 1300,
or 3000 Hz). A Global Navigation Satellite System (GNSS) CCA provides navigation data for
other aircraft systems to support enroute, terminal, precision, and non-precision approach
operations.

The NAV CCA section receives very high frequency (VHF) localizer signals in the frequency
range of 108.00 to 111.95 MHz, and ultra-high frequency (UHF) glideslope signals in the
frequency range of 328.6 to 335.4 MHz. The NAV CCA additionally receives very high
frequency data broadcast (VDB) signals in the frequency range of 108.00 to 117.975 MHz in
GLS mode. The GNSS CCA section receives signals from the Global Positioning System (GPS)
nominal carrier frequency of 1575.42 MHz.
