GPS Receiver
The enclosure is made from 6061 Aluminum alloy. It should be
mounted in a safe location, away from electrical noise and vibration.
We recommend hook & loop or double sided foam tape. Maximum
operating temperature is 70°C or 158°F.
Antenna
The location of the antenna is VERY important. It should be
mounted such that it can have a clear view of the sky out to 5 degrees
above the horizon. Poor mounting locations will have a large negative
impact on the calculated data.
Normally the best location would be on top of the race car. For
motorcycles, the top rear fairing works well. On a closed-wheel race
car the best choice is the roof. For best performance, do not place the
antenna under the front or rear window. For open-wheeled cars, on top
of the roll hoop, or just in front of the cockpit works best.
The antenna has a magnet base to hold itself onto a metal
surface. Any extra antenna wire can be zip tied in a back and forth
bundle. Do not form a coil with the extra wire or wrap it around
anything.
•
GPS signals are easily blocked by electrical noise. Keep the
antenna 12” away from any electrical device. It should also be
more than 6” from any other antennas such as car-to-pit voice
radios, telemetry and other GPS antennas.
•
Keep the antenna outside any of any metal or carbon fiber
enclosed space, as these materials will block satellite signals.
Plastic, duct tape as well as fabric convertible tops are
generally ok.
•
The antenna should be kept flat or parallel to the ground. If
mounted on a slope then the ability to receive signals will
decrease. Keep this in mind when mounting on a motorcycle
as the bike leans from corner to corner.
