Differential and RTK Operations 41
Differential and RTK
Advanced Remote Station Operation
Base Station Data
Both Differential remote stations and RTK remote stations automatically extract the
messages needed from the data coming in to the designated serial port. So you can set
up a combined Differential/RTK base station (see "Setting Up a Combined
Differential and RTK Base Station" on page 31), and operate DGPS remote receivers
and RTK remote receivers.
You can also send RTCM messages from one serial port, while sending Ashtech
DBN messages from another port. You cannot send RTCM and DBN from the same
port.
Any combination of RTCM messages can be sent out of the serial port designated by
$PASHS,RTC,BAS,c. One radio can then be used to support both RTK and
Differential operation, as illustrated in Figure 3.1.
