What Does RTK Add to SLAM Scanning?

RTK adds absolute, real-world coordinates to SLAM scanning. SLAM measures geometry relative to the scanner’s own path, so a SLAM-only point cloud stays in local coordinates. With NTRIP corrections, an RTK-capable receiver records RTK positions along the scan trajectory, and the processing software uses those positions to georeference the whole point cloud.

Final point cloud quality still depends on the scanner, capture conditions and processing, and georeferenced outputs vary by model, software and license. The SLAM point cloud georeferencing guide covers processing; model settings are in the LiDAR scanner RTK setup guides.

NTRIP Service for LiDAR Scanners

NTRIP setup routes are documented for the manufacturers below. Check the exact scanner configurations for hardware and software requirements.

LiDAR Scanner RTK Requirements

A LiDAR NTRIP connection needs suitable RTK hardware, a documented correction input and internet. The entry point may be the scanner, a separate rover, the payload or the aircraft.

LiDAR Scanners with Built-In RTK

CHCNAV RS10 / RS30 and XGRIDS K2 have integrated RTK receivers. Use the model’s NTRIP profile and required internet route.

Factory RTK Options for LiDAR Scanners

Eagle Standard / Max cannot gain RTK after shipping. Select the factory RTK option before shipping; a correction subscription cannot add missing hardware.

LiDAR Scanners with Retrofit RTK Modules

Raven / Raven Max and XGRIDS K1 need the matching RTK module. SHARE C1 / S20 SE also need a Positioning board kit. Check Raven module availability by region.

LiDAR Scanners with an External GNSS Rover

Hovermap Backpack / Vehicle uses a supported external rover and cable. Set up NTRIP on the rover, which supplies positions to Hovermap.

LiDAR Payloads with Their Own RTK Receiver

RTK-configured RESEPI / EchoONE payloads use their own GNSS receiver and internet connection. The NTRIP profile belongs in the payload web GUI.

LiDAR Payloads Using Aircraft RTK

Zenmuse L3 uses Matrice 400 RTK. Enter the service in DJI Pilot 2 on the controller; other aerial scanner routes have their own limits.

Check the RTK hardware for the exact scanner model before starting a correction trial. Use the LiDAR scanner RTK setup guides and check RTK coverage for your scanning location.

For an unclear configuration, share the scanner model, RTK variant and project location.

Connect a LiDAR Scanner to NTRIP Corrections

After confirming scanner compatibility and coverage, activate the service, follow the device’s NTRIP route and check the GNSS solution.

Activate a Free RTK Corrections Trial

Activate the 30-day trial without a credit card. Get the NTRIP credentials from the dashboard after confirming hardware and coverage.

Follow the Scanner's NTRIP Route

Use the LiDAR scanner RTK setup guides for the correction input at the scanner, rover, payload or aircraft. Follow the exact model’s route.

Check the Scanner's GNSS Solution

Assess GNSS status and capture checks using the device guide. Some scanners lack a documented in-scan FIX indicator; include the required result checks.

Reprojection options depend on the scanner, software and source / target coordinate systems; use the SLAM point cloud georeferencing guide.

RTK for LiDAR Scanning Without a Base Station

An eligible LiDAR configuration can receive NTRIP corrections without a personal base station when the documented RTK route, field internet and local coverage are suitable.

RTK LiDAR Scanning Applications

RTK supplies external GNSS position references for suitable LiDAR workflows across buildings, infrastructure, land and airborne mapping. The scanner’s capture and processing method determines how those references are used.

RTK LiDAR for BIM and Digital Twins

For exterior BIM and digital twin capture, RTK provides GNSS references for a compatible scan workflow. Indoor geometry remains dependent on SLAM and the scanner's processing method.

RTK LiDAR for Infrastructure Mapping

Infrastructure capture can use GNSS references to place scans within a project coordinate framework. Repeat visits still need a consistent reference system and independent checks.

RTK LiDAR for Agriculture and Forestry

Terrain and forestry workflows can use RTK where satellite reception is sufficient. Vegetation and GNSS obstruction require the scanner's capture strategy and result checks.

RTK Corrections for Airborne LiDAR Mapping

Airborne LiDAR uses either payload RTK or aircraft RTK, according to the documented configuration. See RTK corrections for drones for the broader aircraft context.

Combining RTK datasets requires consistent reference systems and compatible device / software processing; consult the SLAM point cloud georeferencing guide.

Which LiDAR RTK Setup Do You Have Today?

Once the scanner’s RTK route is confirmed, choose how to get corrections.

I use my own RTK base station

Check the subscription route against field internet and local coverage.

I already have an NTRIP subscription

I need my first RTK correction subscription

Confirm RTK hardware before selecting a plan and stream count.

How to Get RTK Corrections for Your LiDAR Scanner

Path 1

NTRIP Subscription vs Your Own RTK Base Station

An NTRIP subscription can replace the own-base correction route when local coverage and field internet are suitable. An own base may be more practical when those conditions are unavailable.

Requirement	Your own RTK base station	NTRIP subscription
Hardware	Compatible scanner RTK route plus base hardware	Compatible scanner RTK route remains necessary
Corrections	Own base setup and known base position	Online corrections where service coverage is suitable
Cost decision	Existing base equipment and operating setup	Subscription per simultaneous stream
Field condition	Suitable when an own-base route is available	Needs field internet and appropriate local coverage

Compare the correction route using RTK coverage for your scanning location. For an airborne project’s broader method choice, read RTK and PPK for drone mapping.

Path 2

Switching an Existing NTRIP Subscription

Keep the existing subscription while comparing RTKdata at the project location. Use the model’s documented third-party NTRIP route to assess reception and GNSS behavior before changing services.

Profile storage and switching differ by device; follow the scanner guide for the supported procedure.

Path 3

Your First LiDAR RTK Corrections Subscription

Confirm the scanner’s RTK hardware, correction input, local coverage and internet route before choosing a first plan. Count the devices that will need corrections at the same time.

If RTK hardware is missing, return to the LiDAR scanner RTK requirements before starting a trial.

Compatible LiDAR Scanners and RTK Hardware

The documented setup routes below show the RTK hardware, NTRIP entry point and requirements for each scanner configuration. A shared manufacturer name does not make every variant RTK-ready.

Open the LiDAR scanner RTK setup guides for model settings. RTK positioning needs satellite reception; indoor capture follows the scanner’s SLAM workflow.

LiDAR GNSS Accuracy and RTK Service Facts

RTKdata’s 1-2 cm horizontal and 2-3 cm vertical accuracy refers to GNSS positioning under RTK FIX and suitable conditions. Final LiDAR point cloud accuracy also depends on sensors, the scan trajectory and processing.

RTK uses real-time corrections; PPK applies corrections after capture. RTK does not replace independent quality checks, and control points may still be needed for the chosen GNSS / scanning workflow; see the SLAM point cloud georeferencing guide.

Confirm the scanner's RTK route, internet and local coverage. RTK improves GNSS positioning; the finished point cloud needs its own quality checks.

LiDAR Scanner RTK FAQ

Does a handheld LiDAR scanner need RTK?

No. A handheld SLAM scanner can capture local geometry without RTK. RTK adds absolute GNSS position references when the scanner has suitable RTK hardware, satellite reception and a supported correction route. The choice depends on the project’s need for georeferencing. Capture and processing requirements still vary by scanner; consult the SLAM point cloud georeferencing guide.

Does RTK SLAM work indoors or in GPS-denied areas?

RTK positioning needs satellite reception, so an RTK FIX should not be expected indoors or in GPS-denied areas. SLAM can handle local scanning in those sections, subject to the scanner’s capture rules. Outdoor GNSS references do not guarantee indoor point cloud accuracy. Plan the device-specific workflow and independent checks using the SLAM point cloud georeferencing guide.

How accurate is GPS or GNSS positioning on a LiDAR scanner?

RTKdata’s 1-2 cm horizontal and 2-3 cm vertical accuracy describes the GNSS position under RTK FIX and suitable conditions. The figures do not describe final LiDAR point cloud accuracy. Sensor performance, trajectory estimation, GNSS availability and processing also affect the result. Follow the SLAM point cloud georeferencing guide and check the finished dataset independently.

Which devices can connect to an RTK correction service?

A configuration needs an RTK-capable GNSS receiver and a documented NTRIP route. The receiver may be built into the scanner, supplied by a suitable module, connected as an external rover or provided by the aircraft. Exact variants matter, particularly factory-only RTK options. Check the scanner compatibility table and the LiDAR scanner RTK setup guides before starting.

What does an RTK correction subscription cost?

RTKdata plans cost $40/month, $400/year or $1,920 once for five years, in USD per simultaneous correction stream. The 5-Year plan locks the rate for the full five years. One stream connects one device at a time; additional simultaneous scanners need additional booked streams on the same credentials. See RTK correction subscription pricing for the available plans.

RTK Subscription Costs for Multiple Scanners

One stream connects one device at a time. Move that stream between receivers for sequential use; book additional streams on the same credentials for additional simultaneous scanners. Unlimited corrections does not mean unlimited simultaneous devices. Check RTK correction subscription pricing for plans matching the required stream count. Cancel anytime, the paid period runs to its end. Choose the billing period that fits the scanning schedule.

Can RTK corrections be tried without paying?

Yes. The RTKdata free trial provides 30 days of corrections without a credit card. The trial ends automatically and does not renew into a paid subscription. Credentials are available in the dashboard. Confirm the scanner’s RTK hardware and documented NTRIP route, then check RTK coverage for your scanning location before trying the service.

Can the Eagle RTK module be added after delivery?

No. Eagle Standard and Eagle Max need the RTK option selected before shipping; the module cannot be added after delivery. An Eagle without factory RTK has no documented retrofit route. Raven and Raven Max have a separate, documented retrofit module, with availability to check by region. The 3DMakerpro Eagle and Raven guide explains the distinct configurations.
