RTK for Transportation

Lane‑level positioning for mapping, ITS deployments and autonomy pilots via open‑standard NTRIP RTK.

Why RTK matters in Transportation

Corridor and road asset mapping programs depend on lane-level, repeatable positioning. RTK via NTRIP plugs into mobile mapping and ITS deployments, holds FIX along routes, and ties signs, cabinets, and markings back to control—speeding inventory, change detection, and AV/ADAS pilots without base infrastructure.

Centimeter Accuracy

NTRIP corrections for boundary surveys, site layout, and topographic mapping. Achieve consistent centimeter-grade accuracy.

Seamless Integration

Easily connects with mobile mapping rigs and AV development kits. Built on open-standard NTRIP RTK, so there’s no proprietary lock-in.

Live in Minutes

No radios or local base stations required. RTK corrections stream online, reducing setup time and eliminating hardware maintenance.

Fleet Ready

Start with pilot projects and expand to full fleets. One platform scales with your operations and keeps management simple.

Proven Use-Cases in Transportation

From lane-level mapping with 1–2 cm accuracy to powering HD maps, ITS deployments, AV/ADAS, and change detection — RTKdata.com delivers precision GNSS surveying for smarter, safer, and more efficient transportation.

Lane-Level Mapping

Capture centimeter-accurate road geometry and lane markings to power HD maps and ITS applications.

ITS deployments

hardware placement and commissioning at centimeter coordinates without base infrastructure.

HD maps & AV/ADAS

NTRIP RTK positions fed into mapping stacks to maintain consistent localization over time

Change Detection

Before/after surveys that stay in the same frame so deltas are operational, not GNSS bias

Frequently Asked Questions

Do we need a local base station for corridors and ITS work, or is Network RTK (NTRIP) enough?

For most road asset mapping and ITS deployments, Network RTK over mobile data is sufficient and avoids installing or maintaining a site base. A local base is only advisable where mobile coverage is poor, radio redundancy is mandated, or deep urban canyons or heavy canopy prevent a stable FIX. For safety-critical autonomy, RTK is just one input; system-level sensor fusion and certification remain essential.

Will RTK keep a FIX along long routes? What happens when cellular drops?

With good coverage, a FIX will hold along corridors; if coverage dips, receivers may fall back to FLOAT or standalone GNSS. You can reduce disruptions by using multi-network SIMs or roaming to minimize dead zones, selecting mountpoints closest to the route to optimize baseline, choosing receivers that can hold RTK briefly and fusing IMU/odometry to bridge short outages, logging raw data for PPK as a safety net on critical runs, and deploying a temporary or local base where coverage remains weak

What hardware/software do we need to integrate NTRIP RTK into a mobile mapping or AV stack?

You need a GNSS receiver with an NTRIP client (RTCM 3.x), mobile data at the rover, and valid credentials (host, port, username, password, mountpoint). Output NMEA and, where available, high-rate GNSS/IMU to your stack; for robotics, publish to ROS/Autoware using drivers such as nmea_navsat_driver with robot_localization. Time-synchronize sensors using GNSS PPS or a common clock, record QA logs, and verify performance on surveyed checkpoints, where conditions typically allow around 1–2 cm horizontal accuracy.
