List of RTK correction services and NTRIP Casters in Germany
If you’re in Germany and need centimeter-level position accuracy, you’ll need access to an RTK correction service or NTRIP Caster via the internet.
National RTK network in Germany
Germany has established its own national RTK Network to support various high-precision GNSS applications within Germany borders called SAPOS. You can view the SAPOS coverage map.
SAPOS service consolidates data from several operators. This service is free in most federal states, while some states require a fee.
In order to access real-time services, you will need to register on the website or to send them an email to get your NTRIP credentials. Their website is usually not user-friendly, so you will need to find the way to register or contact them. If you have any problem, contact us and our support team will help you.

Free international RTK correction services in Germany
If you only need pass-to-pass accuracy, and you don’t need to compare your measurements with local maps done by other companies, social-based RTK networks are the cheapest way to go. There are also free global correction services with calibrated base stations which are available in Germany. You can use them to achieve centimeter-level accuracy if you are lucky to have a base station close to you (remember that RTK only works up to 35-50 km):
| RTK2GO | Free global community based correction network without quality of service. It is good enough for pass-to-pass centimeter accuracy, but not good for calibrated surveying applications. To view the RTK2GO coverage map, open the page and click "View all" on the top right. Register for the service. |
| IGS | Free global low density high quality correction service. View the coverage map and register for the service. |
| UNAVCO | Free global low-density high-quality correction service. View the UNAVCO coverage map and register for the service. |
| EUREF | Free paneuropean low-density high-quality correction service. View the EUREF coverage map and register for the service. |

Galileo HAS - a free option but lower accuracy compared to RTK
If 40 cm accuracy is sufficient for your project, you can try Galileo HAS, a free, globally available correction service. It works without the internet, NTRIP, or a local base station. While not as precise as RTK, it can still improve positioning accuracy. However, it takes up to 5 minutes to reach full accuracy, compared to just a few seconds with NTRIP.
Not all RTK boards are compatible with Galileo HAS. Here are GNSS RTK receivers that fully support Galileo HAS:
