Real-Time Correction Stream
This service streams real-time RTK correction data generated by GEODNET — the world's largest Network RTK (NRTK) infrastructure. Thousands of multi-band GNSS reference stations continuously observe GPS, GLONASS, Galileo, BeiDou and QZSS signals, and the network converts those observations into correction streams that give your receiver centimeter-level positioning in real time.
As a distribution partner, UCGeo provides this correction data as a managed subscription service: we provision your NTRIP access, help you integrate it with your receivers (including our PBOX29HB RTK receiver), and give you local sales and technical support — one vendor for both hardware and correction data.
Standalone GNSS
Typical 1–5 m accuracy, drifting with atmosphere & satellite errors
RTK Service Enabled
Centimeter-level fixed solutions in seconds, 24/7
The GEODNET network operates as one giant, globally distributed reference station. Corrections travel from field stations to your device in four steps.
18,500+ uniform triple-band reference stations track GPS, GLONASS, Galileo, BeiDou and QZSS on all major frequencies, 24/7.
Station observations are quality-checked and aggregated in the cloud, producing real-time RTK corrections for every covered area.
Your subscription gives you NTRIP caster credentials. Point any NTRIP-capable receiver at the service over cellular or internet link.
Within about 20–40 km of a reference station, your rover resolves centimeter-level fixed positions in seconds.
The correction service is powered by GEODNET, the largest RTK network on the planet — purpose-built to make centimeter-level positioning affordable and globally available.
More than 18,500 base stations live in 142+ countries and 4,300+ cities, with strong density across North America, Europe, South America, Australia, India and East Asia — and new stations coming online every day.
Every site runs the same triple-band multi-constellation receivers, giving consistent correction quality across the whole network — design and test in one country, deploy in another.
GPS, GLONASS, Galileo, BeiDou and QZSS observations on all major frequencies (L1/L2/L5, E1/E5/E6, B1/B2/B3) maximize satellites in view and robustness in challenging environments.
A distributed station model removes land, site and maintenance overhead of traditional CORS networks, enabling subscription pricing far below conventional RTK services — ideal for IoT and fleet-scale deployments.
Correction streams are generated and delivered 24/7 with low latency over standard internet connections, so rovers reach fixed solutions in seconds and keep working around the clock.
The network complements cameras, LiDAR and IMUs to power robots, drones, autonomous vehicles, precision agriculture and machine control with real-time 3D localization.
