So today we’re going to go through the setup of an Eos Arrow Gold GNSS RTK receiver.

We’re going to configure that to work with the Point One Polaris network and show you all the steps involved. So normally you would have this on your survey pole and it would mount to the pole. Here, since we’re inside, we’ve brought an RF connection to our device from an antenna that’s mounted on the roof. So you plug in your antenna and then you’d power on the device. Once you’ve enabled power, you should see some lights on the side. You’ll want to make sure that you see the power LED and that the GPS lights are on. You’ll also occasionally see the Bluetooth indicator blink, indicating that it’s searching for your phone.

So we’re going to go in and open the Eos tools application. We’ll connect to the device and then we want to make sure that we see our approximate position here in the EOS app. The first thing that we’re going to have to now do is set up the differential correction service. So go down to the menu where it says differential and then you’ll see a series of fields. For the IP address, you’ll want to type in the address of the Polaris service. It’s simply in the US and in Europe it will be

Your username and password will be in the Point One Nav web application. So we can switch to that application here in our device list. We’ll have to create a new device. So we’ll go ahead and create an Arrow RTK. You can name it whatever you like and we’ll see that the Arrow RTK device has been created. I can go to that device and see my username and password. So I’m going to go ahead and copy the username, put that here, and then go back, copy the password and paste that in and then hit the Get Mount point button here.

I’m going to be presented with a list of our base stations. You can automatically use the optimum base station by connecting to the Polaris mount point. So go ahead, click that and then you’ll see that the Polaris mount point is selected in the menu. You need to make sure that you have these options all set and you can hit the Start button. And what you should see is a timer start that indicates that it’s now connected to the Polaris service.

If we go and switch back to the status of the device, switch to an RTK fix, and that’s indicating that it has the highest possible accuracy. And you can see the RM’s accuracy reported here is 8mm. So that’s obviously a very good solution and that’s what we’d expect to see on the Polaris network. If I go into the web application, I can actually see that my device is actually reporting its position. Happens to be at our office. This is a very great way to see that both the network is seeing your device and then in the Eos application, we can also see that it’s using the correct service and position and everything.

Furthermore, we can go into the RTK status item and we can see that we have all the different frequencies and signal types across all the different constellations active. And so that’s very good and that’s what you’d expect to see. So at this point we’re ready to survey. You can go ahead and use whatever survey application you like and that will work the standard way that it would for all of the applications that you’re using today with your Eos Arrow Gold receiver.
