The picture above shows a typical 3-antenna placement for the measurement of Body Slip Angle, Pitch and Roll angle.
Antenna A the primary antenna is placed in the centre of the roof. Antenna B is placed behind Antenna A, allowing True
heading, Slip angle and Pitch Angle to be measured. Antenna C is placed to the side of Antenna A allowing the
measurement of Roll angle.
Antenna A is the primary antenna, from which all calculations are based. If overall slip is to be measured (at the centre
of the vehicle), the primary antenna should be placed at the centre of the vehicle. Alignment of the antennas is not
completely essential as the Slip Angle Sensor has the ability to calculate any offset. See the Slip Angle Offset Section.
However if you wish to measure Pitch or Roll then the alignment of the antennas must be in line with the vehicle or at
o
90
as accurately as possible.
When measuring Slip angle Antenna B can be placed either in front or behind Antenna A. If it is placed behind Antenna
A as in the picture above then the 'Swap Antenna' option needs to be enabled in the Antenna configuration options.
