SATCOM (OPTIONAL) (Cont)
The SATCOM system interfaces with a dedicated antenna subsystem to provide satellite communications. A minimum of
three satellite communications channels are required: two voice channels and one data channel. One voice channel is ded-
icated to the flight compartment, and another voice channel is dedicated to the office in the sky (OITS) telephone. The data
channel is assigned for either the airborne flight information system (AFIS) or the OTIS facsimile or modem.
The factory option of the SATCOM consists of a six channel SATCOM system and antenna. Components include:
- Satellite data unit
- High power amplifier
- Radio frequency unit
- High gain antenna.
- Cabin communication system interface via handset
- Airborne data link system
- PC data and fax capability
COMPONENTS AND OPERATION
SATELLITE DATA UNIT (SDU)
Provides interface to all airplane avionics and contains the location of the applicable satellites and rate/frequency transla-
tion for two-voice communication.
RADIO INTERFACE UNIT
The radio interface unit provides three additional simultaneous voice communication channels when operated in conjunc-
tion with the SDU.
HIGH-POWER AMPLIFIER
The high-power amplifier provides rate/frequency power amplification on the L band signals generated by the satellite data
unit or radio frequency unit to a power level required for transmission to the satellite.
SATCOM ANTENNA
The SATCOM system is equipped with one antenna and is located on top of the vertical stabilizer. The SATCOM antenna
is directional and mechanically controlled.
The SATCOM antenna transmits and receives data to the SATCOM LNA/duplexes and the SATCOM antenna control unit
(ACU).
SATCOM ANTENNA CONTROL UNIT
The antenna control unit processes signals from the SATCOM antenna to calculate location. The ACU transmits data to the
SATCOM antenna to control the antenna direction. The ACU gives built-in-test equipment and location data to the SAT-
COM transceiver.
DATA LINK (OPTIONAL)
DESCRIPTION
Data link operation is via the VHF, HF, or SATCOM and is controllable from the FMS CDU. The system utilizes the same
data loading unit as the FMS with air-ground-air and air-to-air capabilities. Crew advisory messages are displayed on the
CDU scratch pad.
