1. Overview
The Norsat Wayfarer is an industrial strength transportable satellite communication system built
strong for the most demanding users working with the most challenging applications and
environments. The Wayfarer is fully automated, integrated, and versatile enough for deployment
virtually anywhere, including mobile field offices, field vehicles, or directly on the ground. A
complete satellite solution, the Wayfarer includes everything to meet your communication needs.
1.1 System Overview
System consists of antenna feedback system, servo mechanism and control system.
Antenna feedback system is the core of the system and consists of reflector, feed horn, LNB,
BUC, OMT and waveguides etc.
Servo mechanism consists of gears, timing belt, gear box, worm gear
Control system has two parts:
•Outdoor unit: Motor driver.
•Indoor unit: ACU controller.

2.2 Turntable (Azimuth and Elevation)
Turntable consists of two main structures: Azimuth module and Elevation module
Azimuth module: Azimuth motor, planetary gearbox and worm gear. The Azimuth transmission is
self-locking in case of power loss.
Elevation module: Elevation motor, planetary gearbox and worm gear. The Elevation transmission
is self-locking in case of power loss.

2.3 Feed Assembly
Polarization modules consist of polarization motor, feed, polarization transmission gear, OMT,
filter and LNB. It can adjust polarization angle and isolate Tx/Rx signals.
The installation location of feed assembly onto boom arm is adjusted in factory. In case of
maintenance, please mark the locations of the feed assembly so that it can be re-installed into
same location.

2.4 GPS Receiver
GPS is installed on the side of the antenna turntable. It collects the latitude and longitude of the
current location for use of ACU and external Modem
GPS transmits lat/log information through serial connection. In order to check the working
condition of the GPS, the enclosure needs to be removed and the indicator lights can be read as
below:
-Indicator blinking: GPS searching signal
-Indicator on: GPS has locked
GPS needs to be locked in auto-acquire when used in a different location than last operation.
2.5 3D Compass

YYYY-MM-DD DOC# Rev 8
3D compass is mounted on back of the reflector to reflect the real time heading, pitch and roll
information.
The compass is calibrated from factory and can provide accurate heading information with hard
iron and soft iron compensation.
Position data is transmitted to antenna through serial connection. The antenna control unit reads
the heading information upon antenna reset and heading information is used for auto-acquire.
Removing two pan head screws and the enclosure gives access to the 3D compass for
maintenance purpose.
2.6 Hand Crank
Hand crank is used to manually drive the antenna in case of emergency.
Do not use hand crank when antenna is powered on
