Tilting target

That's an interesting question and I am guessing you would be in reflectorless mode? May have more to do with the software than the instrument. I have personally never tried, always manually point to a target for a reflectorless shot.

I use stick-on targets similar to those in your photos.

My Trimble S6 will autolock to them, so long as they are close and not at too oblique an angle.

The experiments I have done suggest that it does a pretty good job of finding the target centre.

I do install them rotated by 45 degrees - so like a diamond - which helps

But those reflectors are actually made up of many individual corner-cube reflectors, so I prefer to point the instrument manually to be sure of getting the centre.

I have stapled 40mm targets to one side of 4x4 end cuts and a wire flag on the opposite side to scatter along roadways stacked on top of nails, rods, pipes and rr spikes and such in roadways.

It is cheap and easy and if they get run over I have lost very little if they are ruined.

I have used them from monitoring.

I do not think that a robot would track them well, the newer Leica guns will target reflective tape by ATR, but you cough up a couple mil in centering, so I have always used optical for that application.
