Option 2: Using a Mounting Arm
A flexible way to fix the IMU rigidly within the vehicle is by using the Racelogic Mounting Arm. The three-part telescopic
handle is fully adjustable to any length between 70 and 150 cm to which another 20 cm can be added by extending a
third section using the compression lever.
Both ends are fixed to an 8 cm x 13 cm plate which sits on a joint to accommodate for uneven surfaces. Pressed against
the IMU on the floor and the vehicle's ceiling, the mounting prop ensures that the IMU is fixed tightly.

Option 3: Fixed Mounting
It is also possible to fix the IMU firmly to the body of the vehicle, mid-way along the wheelbase. Try to position the unit
as close as possible to the centre of the vehicle, making sure it is mounted in the direction of travel - as shown in the
image below. It is also important to mount the sensor so that it is level with the ground.
For best results, mount the IMU and GPS antenna as close to each other as possible. For example: Bolt the IMU to the
seat rails and place the GPS antenna on the roof directly above.
Note: The IMU and antenna should be mounted on the same rigid body, to provide a relative reference. So for a vehicle
such as a truck cabin, both the IMU and antenna should be fitted to the cabin body (if cabin is air-sprung) or to the
