GNSS repeater installation for GNSS-L1G1GA
Prior to commencing work on the installation, make a survey of the locations of the individual units,
ensuring that:
1.
The antenna has good line of sight to the sky and is not shrouded or shadowed by buildings, trees
etc. and will not cause an obstruction to doors, windows, or ventilators and is located away from
any machinery HVAC, fans etc.
Always connect the antenna cable before powering the repeater.
2.
The antenna feeder cable can easily be routed indoors and can be properly secured to walls and or
ceilings.
3.
The building protection and integrity is not compromised; i.e. breaching of fire stopped
compartments.
4.
If possible, install the power supply and antenna feeder cables away from existing cables, pipes etc.
5.
There is a nearby power supply to connect the repeater to.
6.
The final location of the repeater allows for maximum coverage of the area.
Install the GNSS repeater transmitter by fixing it to the ceiling, wall or other suitable mounting point. The
repeater has an integrated transmitter TX antenna, located internally, on the same side as the status LED.
The transmitter antenna generally radiates in the same direction as the LED. Ideally the transmitter should
be located so that any desired GNSS receiving location, for example an antenna on top of a van in a garage
has a direct line-of-sight to the repeater antenna.
After installation, prior to switching on, ensure all
connections are tight.
Switch the power on and the indicator LED will flash
green for between two and three seconds during the
start-up phase.
Turn the control knob in order to set the gain. A higher
gain increases the coverage of the GNSS signal.
Watch for the LED flashing to red and green, this means the
maximum power has been reached.
Turning the knob too far clockwise will result in the LED
turning red, indicating the gain setting is too high.
Constant green light indicates proper gain setting. Turning
the knob too far counterclockwise will result in the green
LED to blink indicating too low gain setting.
