Installation
GPS Receiver
The enclosure is made from 6061 Aluminum alloy. It should be
mounted in a safe location, away from electrical noise, vibration and
temperature. Maximum operating temperature is 70°C or 158°F.
NOTE: To counter any possible vibration damage, please mount
the receiver with compliant hook and loop material. In high
vibration environments the RaceGel option is highly
recommended
Antenna
The RaceGrade GPS antenna included
with your unit is an active (powered)
high quality miniature dual band passive
device with a magnetic base. The antenna
is replaceable with our part number M
GPS BL ANT. Older versions of this
antenna are NOT dual band and would
significantly degrade the performance of
the Multi-GNSS feature. If you are
upgrading or mixing parts please be sure to
keep the new antenna paired with the v3
GPS. Non Multi-GNSS units will work with
either antenna, and the new dual frequency
antennas will work with older GPS units.
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 negative impact
on the results from its calculated data.
Normally the best location would be on top of the vehicle. For
motorcycles, on top of the 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.
