ABSTRACT:
A surveying instrument and method determine a duration of a measuring period for obtaining readings of angle values of an angle measuring system in dependence of readings of an error signal produced by a tracking system. It is thus possible to determine a value of the angle represented by the readings of the angle signal with a desired accuracy in the presence of air turbulence wherein the measuring period is shorter at low degrees of air turbulence and longer at higher degrees of air turbulence.
