Intellian v100GX - Connecting Without Ships Gyrocompass

35
INSTALLING THE ACU
Connecting the System without a Ship’s Gyrocompass
For a vessel where the ship’s gyrocompass is not installed or is difcult to be
connected, 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 CCW(Counter Clockwise) direction until the antenna receives
the lock signal from the modem or 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.
