What Is RTK for Transportation?
RTK transportation positioning uses real-time correction data from a reference station network to reduce GNSS errors from meters to centimeters, enabling lane-level accuracy for autonomous driving, vehicle navigation, and logistics operations where standard GPS falls short. RTKdata streams NTRIP corrections directly to any onboard GNSS receiver or ECU, enabling vehicle tracking and connected vehicles to achieve centimeter accuracy. Plans start at $40/month.

Why Use RTK GPS for Transportation?
From autonomous driving to highway surveys, RTK positioning unlocks precision across every transportation workflow.
RTK Autonomous Vehicles & Driving
Standard GPS drifts 1-3 meters, too imprecise for lane-keeping. RTK autonomous driving fuses centimeter-accurate GNSS transportation data with cameras and LiDAR for redundant, reliable RTK vehicle navigation even where visual landmarks are absent.
RTK Fleet Management & Vehicle Tracking
RTK fleet management upgrades RTK vehicle tracking from meter-level to centimeter-level. RTK lane-level positioning lets you know which lane each vehicle occupies, enforce precise geofences, and support RTK logistics with accurate mileage across your entire fleet.
RTK Road Survey & RTK Highway Survey
RTK road survey and RTK highway survey capture centimeter-accurate road geometry, surface profiles, and control points for highway construction and maintenance. Mount a receiver on a survey vehicle and collect precise coordinates at driving speed.
RTK Rail Survey & Connected Vehicles
RTK rail survey provides centimeter-accurate track geometry measurements for alignment verification, clearance checks, and predictive maintenance. RTK connected vehicles across transit fleets use the same corrections for real-time infrastructure monitoring.
Compatible Equipment for RTK Transportation
RTKdata is hardware-agnostic. Any GNSS receiver that speaks NTRIP works out of the box.

Frequently Asked Questions
What is RTK for transportation and why does lane-level accuracy matter?
RTK for transportation uses Real-Time Kinematic GNSS corrections to deliver 1-2 cm positioning accuracy for vehicles, fleets, and infrastructure surveys. Lane-level accuracy matters because standard GPS drifts 1-3 meters, enough to confuse which lane a vehicle occupies. RTK eliminates that ambiguity for autonomous driving, fleet tracking, and road surveys.
How does RTK improve autonomous vehicle navigation?
Autonomous vehicles fuse RTK GNSS with cameras and LiDAR for redundant positioning. RTK provides an absolute position reference accurate to 1-2 cm, enabling lane-keeping, precise stop positioning, and reliable route execution even when visual landmarks are absent or obscured.
Can RTK be used for fleet management and vehicle tracking?
Yes. RTK fleet management upgrades standard GPS tracking from meter-level to centimeter-level accuracy. This enables lane-level vehicle tracking, precise geofencing, accurate mileage logging, and better route compliance monitoring across entire fleets.
What GNSS receivers work for RTK transportation applications?
Popular choices include the u-blox ZED-F9P (affordable, widely integrated in automotive prototyping), Septentrio mosaic-X5 (multi-constellation, high reliability for production vehicles), and ArduSimple simpleRTK2B (plug-and-play for development). All accept NTRIP corrections from RTKdata.
Does RTK work at highway speeds?
Yes. RTK receivers compute positions at up to 20 Hz, and RTKdata NTRIP corrections arrive within 100-300 ms over 4G/LTE. This is well within the requirements for highway-speed lane-level positioning and autonomous driving applications.
How is RTK used for road and highway surveys?
RTK road survey uses centimeter-accurate GNSS positioning to map road geometry, measure surface profiles, and establish control points for highway construction. Survey crews mount RTK receivers on vehicles or survey poles to collect precise coordinates along road centerlines and edges.
Can RTK support rail survey and railway infrastructure monitoring?
Yes. RTK rail survey provides centimeter-accurate track geometry measurements for alignment verification, clearance checks, and maintenance planning. RTKdata corrections work with any NTRIP-compatible GNSS receiver used in rail surveying workflows.
