How to Use the Leica Viva GS15 GNSS Receiver With Your Pacific Crest ADL Slot Radio

Want to learn how to use your Leica Viva GS15 GNSS receiver with a Pacific Crest Advanced Data Link (ADL) slot radio as a base and rover? This easy how-to guide will show you how to select the proper settings in just five easy steps.

In the main menu of SmartWorx, you will be connected to your rover. (In our demo, we are using a Leica simulator.)

Step #1

Once connected to your rover, the first thing you’ll want to check is your RTK settings. Do this by clicking on the “star” key on the data collector. Then, click on “RTK Settings.”

Make sure the box is checked to “Receive RTK data.” In our simulator, we are going to connect using GS Port 3. This is the port on the GS15 where we have our Pac Crest ADL slot radio.

Also, if you are using the external antennae on the GS15, make sure you have this box checked. If you are not using the external antennae, make sure this box is unchecked.

Make sure you have the same RTK data format between the rover and the base. For most applications, you will use the Leica 4G data format.

Leave the other boxes unchecked and don’t worry about the other tabs (RTK base, RTK network, Advanced). Click “OK.”

Step #2

The next step is to check the radio channel settings.

Again, click on the “star” key on your data collector. Select “Change Radio Channel.” Here, you can choose your radio channel. To change the channel, simply highlight and write in another channel. The yellow bar at the bottom will tell you if your channel has been accepted.

“Actual frequency” tells you the frequency of your channel.

Once you set your channel, click “OK.”

Now your settings and your radio channel have been set properly for the rover.

Step #3

Now, let’s look at the base. To connect to the base, click on the “Go to Work!” icon. Then, click on “Go to the base menu” and we’ll do the exact same thing here that we did on the rover side. Wait for the base receiver to connect.

Click on the “star” key. Then, click on “RTK Settings.”

Make sure the “Transmit RTK base info” box is checked. Our radio is in GS Port 3. The device is called BASE ADL. (You cannot use Pac-Crest ADL since this was already used on the rover side.) Check the box “Use external antennae on GS15” if using the external antennae. If not using the external antennae, make sure this box is unchecked.

The RTK data format should be the same as what you are using on the rover. In this case, this is the Leica 4G. These settings should match what you have set on your rover (other than the device, which in this case is different.) Click “OK.”

Step #4

Now, click on the “star” key again. Select “Change Radio Channel” from the main menu. Make sure this radio channel is the same channel as what you have set for the rover. Once you are sure your base and rover are both on the same channel and frequency, click “OK.”

 

Step #5

Again, click on the “Go to Work!” icon. You can now choose one of three options – over known point, over last setup, or over any point – to set your base.

After your base is set, you should see a lightning bolt pulse outward since this is a base. (Also, physically on the GS15, if you look at the two lightning bolts, you should see a green light blinking underneath the lightning bolt that’s going outward.) When you see this lightning bolt, return to the rover. It might take a few minutes for the rover to connect to the data collector.

Once it is connected, again look at your radio icon to see that the rover is receiving information from the base. The lightning bolt will be pulsing inward. (If you physically look at your GS15, you should see the green light below the inward lightning bolt blinking green.)

That’s it – you are ready to work!
