Autobase Feature 8
Trimble recommends that after any new base station setup, or at the start of each
measurement session, that you measure a known point to verify that position and height
errors are within tolerance. This is good practice and it takes just a few seconds to
potentially eliminate gross errors typically associated with repeated daily setups of the
base station.
