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 Ashtech 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 Ashtech
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.
