AiM accuracy
Automatic target aiming accuracies, like those of the AiM, are in general the same as the stated
angular accuracy. Therefore these accuracies are also distance-dependent parameters.
External impacts, like heat shimmer, rain (prism surface covered by rain drops), fog, dust, strong
background lights, dirty targets, alignment of the targets etc. can have a significant influence on
the automated target. In addition the selected EDM mode affects the AiM performance. Under
good environmental conditions and with a clean, properly aligned target the accuracy of the
automated target aiming is equivalent to the manual target aiming (presumed valid calibration
values).
Type and centring accuracy of the prism
The prism centring accuracy depends mainly on the used prism type, for example:
Prism type

GeoMax GRZ122

Additional influencing factors
When determining absolute coordinates, the following parameters can also affect the resulting
accuracy:
•
Environmental conditions: temperature, air pressure and humidity
•
Typical instrument errors, such as horizontal collimation error or index error.
•
Proper functioning of laser plummet or optical plummet
•
Correct horizontal levelling
•
Setup of the target
•
Quality of additional equipment, such as tribrach or tripod.
