Hardware Setup
There are two components used to collect RTK quality data – the RTK PCM mounted to the
boat and RTK Base Station.
Figure 16 shows the Bluetooth option with the RTK option.
RTK PCM (Boat) Assembly
1. Connect the GPS high gain antenna to the aluminum mast by screwing the male threads
on the mast into the antenna receiver.
2. Connect the mounting bracket for the antenna mount to the ADP by inserting the four
thumb screws located on the mounting bracket into the four brass holes on the ADP.
3. Connect the coaxial cable to the PCM and the GPS antenna by connecting the female con-
nectors on the coaxial cable to the male connectors in the PCM and GPS antenna.
4. Turn the system on by pressing the power button on the PCM.
5. RTK quality data requires that the RTK Base Station be installed within 2 kilometers of the
PCM. The RTK Base Station setup is described below.

RTK Base Station
1. Figure 17 displays an assembled RTK Base Station and tripod. The tripod should be in
close proximity to the measurement section (less than 2 km with good line-of-sight) and
mounted so that it is reasonably level. Also, nearby obstructions such as bridges, buildings,
or large trees should be avoided if possible. These obstructions limit the number of useful
satellites increasing the required time to obtain an RTK correction.
2. Attach the tripod adaptor (round plastic disk) to the RTK Base Station until there is a tight
fit. Now attach the tripod adaptor to the tripod by screwing the brass thumb screw into the
bottom of the tripod adaptor.
3. Attach the Base Station antenna mount to the top of RTK Base Station housing over the
brass inserts. Use the four thumb screws on the antenna base mount to secure the mount
to the RTK Base Station.
