RTK Configuration Steps
Direct IP Connection To Your Own Base Through GPRS Modem
and RTDS Software
Introduction Until recently, Direct IP connections from Spectra Precision
rovers were possible only with third-party reference stations.
Today, with the Spectra Precision RTDS

software, you can
also have your own base transmitting its corrections to your
rovers through a Direct IP connection.
In this configuration, the RTDS software serves as the
relaying device between the base and the rovers. The
presence of a relaying device is required because modems are
assigned an IP address by the network when they connect to
it, and this IP address cannot be known ahead of time for
both modems. The RTDS software solves this problem by
providing a fixed IP address through which that base and
rover modems can communicate.
