INSTALLING THE ACU
Connecting the System without a Ship’s Gyrocompass
For a vessel where the ship’s gyrocompass is not installed or is difficult to connect,
the Intellian Gyro-Free satellite search function will be automatically
enabled to allow the antenna to lock onto the desired satellite without
requiring an external heading input.
The table below provides an example of the Gyro-Free satellite search algorithm. The
Search 1 or Search 3 satellite search pattern will be triggered according
to the existence of heading input and the setting of the heading device.
Search 1: The antenna will search for the target satellite by turning its azimuth
angle in a CCW(Counter Clockwise) direction until the antenna receives a
lock signal from the Modem or until the DVB(Digital Video Broadcasting)
transponder of the target satellite is decoded by the antenna.
Search 3: The antenna will search for the target satellite by turning its azimuth angle
directly to the position calculated using the ship’s heading input and lock
onto the satellite.
Quick Setup Procedure
• Set the satellite having DVB transponder as the target satellite.
• Set “No Device” to the heading device.
• The antenna will search for the target satellite by turning its azimuth angle in
a CCW direction and lock onto the satellite signal until the antenna receives a
lock signal from the Modem or until the DVB transponder of the target satellite is
decoded.
• Set the heading device as NMEA
- Enter the “Manual search” menu and press the “Function” key to save the current
settings. Intellian's ACU will automatically calculate and save the BOW offset.
- Upload the real TARGET satellite pre-configured from the library.
