RTK Implementation
Activating a Data Link in Direct IP Mode
In this mode, you will have to:
• Enter the two identification parameters of the RTK
correction data provider, i.e. IP address (xxx.xxx.xxx.xxx)
or host name (a URL name), and port number.
• Wait until the data link is active and RTK correction data
is received.
NOTE: Introduced late 2008, the RTDS PC software allows
rovers to communicate with a user-owned base, also through
the Direct IP mode. The software serves as a relaying device
between the base and the different rovers used in the field.
This is an attractive solution for users who want to work in
standalone mode. In this respect, this solution resembles that
of the radio link, but without its radio coverage limitation as
long as there is a cellular coverage in the working area.
Monitoring the
Data Link
Making sure the data link is operational at all times is
essential to successful field operations. A good indicator to
monitor the data link is the age of corrections. This parameter
is clearly highlighted on the display screens of all Spectra
Precision receivers or field terminals.
When the data link operates normally, the age of corrections
is continuously equal to the transfer rate set at the base for
transmitting RTK correction data. If for any reason, a
correction data set is not received or the rover fails to decode
and use it, then the age of corrections will start increasing.
