According to this discussion the Emlid units don’t include tilt into the calculation of the surveyed point. That means we will add some error by off nadir.
In the marketing materials it looks like this is not an issue and measuring points without a bipod is possible. In construction it’s the resulting accuracy might be sufficient though?
Emlid offers also a survey pole for the RS2+ unit. What is the accuracy of the bubble level?
The best bubble level I cloud find has 10’ (arcminutes) accuracy (6mm lateral error @ 2.234m). Does it make sense to use very short pole even if it means the the antenna has a less optimal position?
