(Reporter 50, April 2004) Over the last few years, permanent reference station
installations have emerged in several countries.
These installations allow for roving GPS users in the
field to achieve instant centimetre accuracies without
the need of setting up a GPS reference station on a
known station. This is quite appealing, since in areas
with considerable GPS surveying activity, a number
of users might share the infrastructure and the associated
costs. Some of the installations are operated
by companies and provide a service to the surveying community.
