I have created an example driver for the range of Advance Navigation INS devices eg Spatial, Spatial Dual, Spatial FOG, Spatial FOG Dual, Motus, and Orientus.
The repository can be found here: https://github.com/an-scott/Advanced_Navigation_driver.
If anyone has any questions, do not hesitate to contact me.
