How to setup RTK corrections in your GIStar application

Setting up an RTK network in your GIStar surveying application

This guide will explain you on how to setup your GIStar GPS survey application with an RTK network like RTK FIX. When you connect your GIStar surveying application to an VRS RTK network there are a few things that need to be setup correctly in order to receive correction data. In this guide we have used the South X6 handheld GPS receiver with GIStar software.

Step 1

In this example we will use the South X6 with GIStar. To start make sure you have an active internet connection and that your GPS receiver has sufficient satellite coverage.



To start, click on the receiver icon in the top right corner of your screen

Step 2

Once in the LBS manage section, for the first time use you will first have to start it.


So before clicking on settings you click on Connect

Step 3

Once you have clicked on Connect it will say “failing Connection”. This is because nothing is setup yet.



To setup your Surveying software with RTK you click on “Setting”

Step 4

In settings, make sure your datalink is set to “Data collector internet”. This will take the internet of your device.


Next you go to “Network settings” to setup your VRS RTK network details.

Step 5

In this step you fill out the details you have received from your provider. For RTK FIX you fill in the following details: 

  • IP    =  (OR
  • Port = 2101
  • Select NTRIP
  • Username = Fill in you RTK FIX details
  • Password = Fill in you RTK FIX details

Step 6

In this step you will have to select your Mountpoint. GIStar call it a sourcetable.


You can either write it yourself or, for ease of use, fetch it from our servers. Just click on refresh and it will download all the available mountpoints from our server.


Note: if you are not able to download the mountpoints this probably means that you don’t have an active internet connection. Please check your internet and try again 

Step 7

Once you have clicked on refresh you can see the entire list of available mountpoints.


RTK FIX has made it easy for you. You can just select the country that you’re in and you’re ready to go. 

Step 8

Once everything is setup you are good to go. One last option is “automatic connection”. With this feature it automatically connects to the RTK FIX correction network on startup. So next time just turn on your device and you’re ready to go.


When everything is setup you click on Connect

Step 9

When you go back to the previous screen you should see in the solution tab either SINGLE, DGPS, FLOAT or FIXED. 

  • SINGLE – You probably have bad satellite coverage
  • DGPS    – You probably have bad satellite coverage
  • FLOAT   – Your receiver is processing the correction data. It is just not sure of its accurate position and thus is not centimeter accurate
  • FIX        – Your receiver is processing the correction data and is sure of its position. You are now centimeter accurate

Step 10

Once everything is setup you are good to go! On the top left of the screen you can see the solution status and the accuracy of your receiver. In this test the receiver was hanging out the window so that’s why it only got an accuracy of 2 centimeters.
