1.27 mm spacing.

Co-ordinate frame and origin point
The xOEM uses a co-ordinate frame that is popular with most navigation systems. Figure 4 shows
how the axes relate to the xOEM board. All measurements to and from the xOEM should be made
from the measurement origin point shown in Figure 7. The origin point is the same for all xOEM
models.

Table 6 lists the directions that the axes should point for zero heading, pitch and roll outputs when the
default mounting orientation is used.

The xOEM can be mounted in any orientation, it is not necessary for its axes to match those in Table
6. If a different mounting orientation is used then it must be specified in the configuration file. This can
be accomplished with the NAVconfig software.
