Resection (Backsight) Trible Access

Question asked by Eric Daley on Jan 30, 2019

When performing a resection there is an tickbox to select a control point as 'Backsight'. Is there any detailed documentation on what this does exactly? The help manual doesn't go into detail (see 2b)

To complete a resection 


My question is as follows. If the 'Backsight' tickbox is ticked for PointA and unticked for PointB, does this mean the orientation is set to PointA?

If PointA is 100m away and PointB is 20m away, it is more preferable to set the orientation to PointA.


Lieca has a feature where the orientation is set to the first observation. Does Trimble have a similar feature?
