RiverSurveyor S5/M9 System Manual (February 2013)

3.6.

Configuration E – SonTek Differential GPS

3.6.1.

Description

Figure 18 shows the RiverSurveyor system with Standard DGPS and wireless communications
using a SonTek Hydroboard. The standard differential GPS option has sub-meter precision. The
SonTek Hydroboard is used below for conceptual purposes.

Figure 18.Wireless Communications DGPS

3.6.2.

Hardware

Below are the directions for mounting the hardware for the DGPS option.

Figure 19 displays the hardware necessary for the DGPS option.

1. Connect the female connector of the coaxial cable to the male connection on the receiving

antenna. Run the coaxial cable through the antenna mast to the bottom, collecting all ex-
cess cable from the antenna mast.

2. Attach the GPS receiver to the mast by screwing the female connector of the antenna to

the male connector on the mast.

3. Attach the GPS mounting bracket to the ADP by inserting the four thumb screws into the

brass holes in the ADP. Now attach the antenna mast to the mounting bracket by screwing
the male threads on the mast to the female threads inside the mounting bracket.

4. Connect the female connector of the coaxial cable to the male connection on the PCM.

5. Turn the system on by pressing the power button on the PCM. Follow the instructions in

Section 5 to complete the discharge measurement.
