12-2 - VB3i IMU Integration - Roof Mounted

When using the IMU roof mount, the user has the option to translate the data from the roof to another point on the
vehicle. By default, when the roof mount is enabled, a 1 m Z offset is added, translating the filtered speed down in to the
vehicle, towards the centre of gravity.

If the Kalman Filter data is required relative to an alternate or more precise location on the vehicle, then measurements
should be made from the centre of the IMU to the desired location. As the IMU is housed within the enclosure, precise
measurements are not easy to make. So a Z measurement can be taken from the centre of the GPS antenna, provided
3 cm is subtracted from the physical measurement. Translation measurements need to be made in all 3 axis, X, Y and
Z.

Required equipment
