OxTS vehicle frame
The OxTS vehicle frame is attached to the body of the vehicle. It is related to the INS through the rotations in
the Orientation page of NAVconfig. It can be changed while the INS is running using the Quick Config tool of
NAVdisplay. The definitions of the vehicle frame are listed in Table 20 and shown in Figure 15.

X This is the forward direction of the vehicle
Y This is the right direction of the vehicle
Z This is the down direction of the vehicle
The OxTS vehicle frame is attached to the vehicle and rotates with it in all three axes. The X-axis remains
parallel to the vehicle’s heading, while the Y-axis points to the right and is perpendicular to the vehicle’s vertical
plane of symmetry.
ISO 8855 vehicle system
The ISO 8855 vehicle system is attached to the body of the vehicle. At rest, the X-axis points forwards
horizontally and is parallel to the vehicle’s longitudinal axis. The Y-axis is perpendicular to the longitudinal axis
and points left. The Z-axis is orthogonal to the X- and Y-axes. Definitions are listed in Table 21 and shown in
Figure 16.
