Global NTRIP RTK Corrections for Drones, Robotics & Autonomous Systems
RTKsub provides real-time RTK correction data via NTRIP for drones, robots, surveying equipment and other RTK-capable GNSS systems. It enables centimeter-level positioning without the need to deploy and maintain a local base station.
RTKsub is rated 4.8/5 on Google by RTK specialists.
RTKsub provides real-time GNSS corrections for OEMs, system integrators and operators of UAVs, UGVs, USVs, robots and other autonomous platforms that require accurate and repeatable positioning.
Centimeter AccuracyCentimeter-level positioning supports precision navigation, mapping, surveying, inspection and automated operations where reliable and repeatable location data is essential.
Low-Latency CorrectionsRTKsub delivers real-time correction data via NTRIP for fast and reliable positioning of RTK-capable systems in motion. Correction streams support GPS, Galileo, GLONASS and BeiDou.
Broad Global CoverageAccess RTK corrections through a global network of 22,000+ base stations across 170+ countries. Operators can check coverage for available stations near their project location.
Ready to IntegrateRTKsub uses the standard NTRIP protocol and works with compatible RTK-capable GNSS equipment. Setup is straightforward, with support available for configuration and field use.
RTKsub adds real-time correction data to compatible GNSS equipment, enabling significantly more precise and repeatable positioning than standalone GNSS.
| Standalone GNSS | RTK with RTKsub | |
| Positioning Accuracy | Meter-level | Centimeter-level* |
| Real-Time Corrections | No | Yes, via NTRIP |
| Repeatability | Limited | High with RTK fix |
| Correction Source | None | Global RTK network |
*Performance depends on equipment, satellite visibility, network coverage and operating conditions.
