Mounting
The VBOX 25 Hz Speed Sensor should be secured
inside the vehicle to stop it from moving when
the vehicle is in motion.
The base plate has M3 screw holes along its length that
you can use if you want to bolt it directly to a mounting
surface in the vehicle.
Alternatively, the Racelogic Mounting pole is compatible
so you can mount the
unit vertically. Contact
information or to order a mounting arm (RLACS212-V2)
and/or mounting bracket (RLACS291).
Antenna Placement
Appropriate placement of the GNSS antenna is crucial to the quality of the data that is being recorded.
Be aware of objects that can shadow the antenna or block the signal to the antenna. Some objects can also reflect
signals which can send weaker GNSS signals to the antenna. This is called multipath, and these reflections can disturb
the signal in an unpredictable way.
If an antenna is not mounted on a large enough ground plane, multipath reflections can also come from the ground
beneath the antenna.
Note: You can find in-depth information about how to place the antenna on a vehicle and how to use the satellite
elevation mask here.
