Test results may be biased due to atmospheric conditions, baseline length, GNSS antenna type,
multipath effect, number of visible satellites, and satellite geometry.
2
The measurement uses 1 km baseline and a receiver with good antenna performance, regardless of
possible errors of antenna phase center offset.
