In general, the correct mounting of GNSS modules must be observed in order to obtain a usable measurement result.
Basically, the output, raw speed of the GPS/GNSS module is a result of the current vehicle speed, the speed of movement of the vehicle due to e.g., pitching movements when braking and the speed caused by inherent movements of the GPS/GNSS module due to poor installation.
The latter can be caused by vibrations of the poorly mounted module or incorrect values caused by the speed of the GNSS module’s own movement e.g., due to the tilting movement of the module during heavy braking.
It is very important that the GPS/GNSS module must have clear view to the sky to get the best possible GPS/GNSS satellite reception!
It is recommended that the module be mounted evenly on a solid metal plate using high quality double-sided tape at a location on the vehicle that is not shielded from other parts of the vehicle.
Thereby three advantages are gained:
- A metal plate or carbon fibre parts are acting as an “amplifier” and strongly improves the GPS/GNSS signal reception. If no metal plate or carbon fibre is used as mounting base, a self-adhesive ground plane for GPS modules (AC-GPS_ground_plane-000) must be used
- Much better mounting possibilities are achieved when using a metal plate because the antenna can be mounted even and fix on the plate with double-sided adhesive tape to reduce movements of the antenna itself
- By fixed mounting on plate the mass of the antenna is increased and thereby the impact of external vibrations on GPS-chip is greatly decrease

To fix the GPS2CAN, 12 Hz Mouse or 25 Hz Mouse with screws the aluminum mounting plate (AC-GPS2CAN_Mountingplate-000) can be used.
