Conditions of use: External antenna used, baseline < 10 km,
difference of altitude between base and rover <50 m
Initialization in Networks
If you are working with a single Physical Reference Station
(PRS), performance figures should be equivalent to those giv-
en in the above table, in the same operating conditions.
Performance figures will also be of the same level if you are
working with a Virtual Reference Station (VRS), provided the
distance between the master station (i.e. the PRS used for
creating the VRS) and the rover is less than 10 km.
