Real-Time Kinematics (RTK) basics:
What is RTK (Real-Time Kinematic)?
RTK stands for Real-Time Kinematic and is a technique that enables higher accuracies than stand alone GNSS receivers do, based on permanent fixed reference points/stations. The basic concept is to reduce and remove errors common to a base station and rover (receiving unit) pair. Therefore a data link connection must be established. The rover sends out his satellite position and receives recalculated correction data from the network for these specific satellites.
How does RTK work?
Reference stations never stream correction data 1:1 to the rover. Instead reference stations are used only for observations (measuring) and sending this ‘raw’ data to our data center. At the data center all observations from all stations are used to create a model of the errors over a certain geographical area (like a topographic map, but instead of showing elevation, it shows error. Rover sends NMEA (National Marine Electronics Association) for authentication and initial position. Depending on the location of the rover in that model, a customized correction signal is sent to that rover to compensate for the errors on that location. This is real-time, so if the rover moves to another location, the applied corrections will also change. If the nearest station goes offline, no problem. There is no 1:1 communication. It just means there is 1 less measuring station to share observations to build the model. The rover is not receiving corrections from stations, it is receiving corrections from a solution.
What is RTK used for?
Everywhere a precise position is required you can rely on RTK (as long as it is outside):
- Construction and surveying
- Precision farming and robotics
- Autonomous driving
- Several applications related to unmanned aerial, ground or maritime vehicles
- Monitoring and telematics
What are the requirements for RTK (hardware/circumstances)?
- GNSS Antenna, capable to process and use incoming RTK corrections
- Data Modem with a connection to (mobile) internet
- Access to internet for Ntrip protocol based data transfer
- A clear view to the skyplot of satellites, these are ideally maximum distributed. No shadows or blocking from a.e. trees or buildings
Why a RTK Premium Network?
- Currently Premium Positioning covers more than 25 countries in Europe.
- Additionally parts of north america, south africa and Japan is available.
- Over 1500 linked reference stations deliver EU certified ETRF coordinates
- More than 30.000 users are registered in our Network and rely on the availability and accuracy that we deliver every day.
What can I do with the RTK Live Map?
In the RTK Live Map you can check the rover history. This is the place where you can see the status of the rover; all the connections and positions re-directed to the network will be shown there.
Here you can find detailed information regarding Satellite connections, RTCM settings, and a detailed overview of the status of the rover.
How to access Rover History:
- Open RTK live Map.
- Click on “rover history” on the left bar.
- Enter Rover's name and time period -> press ok.
- The Rover History Table will show all the data collected during the selected time period.
- Select the time period that you need and click on the map icon in the right menu bar.
- Zoom on the map to see the rover's path.
- Click on the color circles, and a pop-up window will open with detailed information about the rover.
