•
Adjustments for air pressure
•
Air temperature
For highest precision distance measurements, the atmospheric correction
should be determined with:
•
An accuracy of 1 ppm
•
Air temperature to 1 °C
•
Air pressure to 3 mbar
Atmospheric corrections in ppm with temperature [°C], air pressure [mb] and
height [m] at 60% relative humidity.
