2.3.5 Typical Network Configuration for VanLink
2.3.5.1 GPS/IMU Mounting Considerations
In order for the GPS/IMU to continually provide accurate heading information a few
considerations need to be made when mounting the assembly on the roof of the vehicle.
• The GPS/IMU assembly must be mounted as far away from any significant sources
of current such as flood lights or motors as possible because it is sensitive to EMI
generated by these types of devices.
• It’s recommended that it be installed at least 24” from the pan/tilt device so as not to
be affected by the EMI generated by the DC motors.
• The GPS/IMU can be mounted either on the mast using a bracket or on the roof of
the van in an area least likely to be affected by EMI.
— If it is mounted on the mast, six (6) additional wires will be needed to be run
through the NYCOIL.
