Signs, offsets and mount angles in EIVA software:


Q. How is the sign conventions changed between NaviPac and NaviEdit?

E.g. I have an offset in the convention for NaviPac (With positive z UP): x=0,y=-5.08, z=0.13. 

I want to add this offset as a user offset in NaviEdit (With positive z DOWN).

Should the offset be x=0,y=-5.08,z=-0.13?


A. Yes.

The z sign convention value are opposite in NaviPac (Aquisition) and NaviEdit (Postprocessing).

When importing NaviPac data into NaviEdit, NaviEdit automatically changes the sign.

If you use the NaviPac data in other applications, you need to change the sign manually.
