Figure 4-2: BNO080 mounted in a device 
This rotation would be represented by a quaternion of (
,0,0,
). 
Assume that for the device the BNO080 is mounted in, the Z-axis is Up, the X-axis is East and the Y-axis is North. 
Examples of mappings for BNO080 mounting are provided below to clarify the use of the FRS record:
