Using RTC Bridge The RTC Bridge function is typically used to allow a rover to
forward the RTK corrections it receives from an RTK network
through its built-in modem to other rovers operated in the
vicinity, using a license-free radio transmitter connected to
its serial port. Being a low-power unit (<500 mW),the license-
free radio can be powered directly from the receiver, without
the need for another external battery.
Starting RTC Bridge is a three-step procedure:
• Mounting the license-free radio onto the range pole and
connecting it toport A using the Y-shaped cable supplied
(USB connection is for powering the radio, the other
connection to the serial port is for the data).
• Setting the license-free radio, then the GPRS modem,
using FAST Survey.
• Activating RTC Bridge through a serial command
($PASHS,BRD) sent from FAST Survey.
This procedure is detailed below.
