Base, Rover or Relay? How to Use DJI D-RTK 3 in a Canadian Mapping Workflow
Choose Broadcast/Base mode when compatible aircraft need real-time RTK corrections; choose Rover mode when the field team must measure control points or independent checkpoints; choose Relay mode when site conditions obstruct or degrade the direct command-and-control path. In a defensible Canadian mapping workflow, those jobs are separate: establish the coordinate authority, verify the live DJI compatibility matrix, collect control and checkpoints, preserve observation files, and validate the final deliverable. D-RTK 3 can support centimetre-class positioning under DJI’s stated conditions, but neither a FIX status nor a device specification proves map accuracy. Relay mode does not by itself qualify an operation for BVLOS; the mission must meet the applicable Transport Canada category and requirements.

The quick decision: assign one job to each mode
DJI’s current web support material uses “Broadcast Mode,” while its specifications, user manual and release notes also use “Base Station Mode.” This guide uses Broadcast/Base for the same correction-broadcasting role. DJI documents Broadcast/Base, Rover and Relay as selectable operating modes; plan one active mode per station.
Correct the aircraft in real time
Use this mode when one or more currently compatible DJI aircraft need correction data from a stationary D-RTK 3 during data capture. Establish and record the station coordinate before flight, keep the station fixed, and monitor RTK status throughout the mission.
Measure ground points
Use Rover Mode as a handheld mapping tool for control points and checkpoints. Connect the DJI Enterprise app to an appropriate RTK source, enter the pole height correctly, classify each point by purpose, and export the field record for processing and QA.
Work around signal obstruction
Use Relay Mode when terrain, buildings or other obstructions degrade the direct communication path. Place and secure the station high and unobstructed, validate the link on site, and remember that the relay changes communications architecture—not operating authority or proof of survey accuracy.
Best-practice verdict: start with the deliverable and the site risk, not the device. A mapping team may use Rover to measure checkpoints on one part of a job, reconfigure the same station as Broadcast/Base for a flight, and preserve Broadcast observations for possible PPK. DJI documents one selected operating mode per station. Current 1+N workflows use separate base and rover stations—not one physical station running all three modes at once.
Broadcast/Base vs Rover vs Relay
The table below separates setup, connection, records and QA responsibility. Always verify the current supported configuration on DJI’s live D-RTK 3 pages before committing an aircraft, controller, app or firmware version to a project.
| Decision point | Broadcast / Base | Rover | Relay |
|---|---|---|---|
| Main job | Provide correction data to compatible DJI aircraft during capture. | Measure ground control points, checkpoints and other field points. | Bridge communications when the direct controller-to-aircraft path is obstructed. |
| Field setup | Stable tripod position, clear sky view, established coordinate, no movement after setup. | Survey pole, correct pole height, suitable RTK source, point naming and classification plan. | Elevated, fixed, unobstructed and interference-aware position, selected after a site assessment. |
| Connection logic | DJI currently says Broadcast Mode can connect with multiple compatible DJI aircraft. | DJI currently says Rover Mode pairs with one mobile device by Bluetooth. | DJI currently says Relay Mode connects with one remote controller and its paired aircraft. |
| Field output | Live correction status plus raw observation DAT records created for a powered session. | DJI Terra-compatible JSON mark export and CSV results/checkpoint export; confirm the exact files exposed by the installed app version. | Communication link status plus raw observation DAT records when the station is used for a powered session. |
| What it does not prove | A FIX indication does not prove the delivered map meets the project tolerance. | A recorded point is not automatically correct, independent or in the intended coordinate reference system. | A stronger link does not by itself qualify an operation for BVLOS and does not validate positional accuracy. |
Compatibility, radio availability, app behaviour and firmware support can change. Do not treat this workflow guide as a substitute for the current DJI compatibility information, manuals or release notes.
How to use Broadcast/Base Mode without losing coordinate control
Before capture
- Confirm the exact D-RTK 3 regional version, aircraft, remote controller, application and firmware combination on DJI’s current official pages.
- Select a stable location with a clear sky view and suitable coverage of the takeoff and measurement area.
- Define the project coordinate reference system, vertical reference, units and expected deliverables before establishing the station.
- Establish the base coordinate using the method approved for the project. DJI’s current support material lists network RTK calibration, PPP calibration and manual calibration options.
- Record station identification, coordinate source, setup time, antenna or instrument height where applicable, operator and firmware/app versions.
During and after capture
- Keep the station fixed. DJI states that movement is monitored and that detected displacement triggers a warning and interrupts the mission workflow.
- Watch RTK solution status, satellite geometry and any correction interruptions; log anomalies rather than assuming the status recovered cleanly.
- Run planned independent checks before leaving the site, including repeat observations where the project specification requires them.
- Archive the matching DAT observation file, mission log, station record, image set and processing notes under one project identifier.
- Validate the processed surface, point cloud, orthomosaic or model against checkpoints and the client’s acceptance criteria.
Critical distinction: the station can support precise positioning, but the final result still depends on the coordinate entered, satellite conditions, multipath, electromagnetic interference, camera calibration, flight geometry, processing choices, ground-point quality and the way accuracy is tested. DJI’s own product notes state that measurement performance depends on conditions including clear view, satellite distribution, ionospheric activity and interference.
How Rover Mode fits control and checkpoint collection
Rover Mode turns D-RTK 3 into a handheld field measurement tool used with the DJI Enterprise app. DJI’s current support instructions describe entering NTRIP credentials supplied by a network RTK service provider, entering the survey-pole height in the app, and exporting point data from the Mission Library. The correct RTK source and coordinate setup remain project decisions.
Control points
Control points are observations the processing workflow may use to constrain, transform or assess the reconstruction. Their names, coordinate reference system, units, vertical reference and marking quality must be deliberate and traceable.
Checkpoints
Checkpoints test the finished result independently. Do not use the same point as both a fitting control point and an independent checkpoint. Distribute checkpoints across the site and across relevant elevation and surface conditions.
Field evidence
Keep the exported point file, point descriptions, photos or sketches, pole height, observation times, RTK source, solution status and any repeat measurements. A coordinate without context is difficult to audit later.
Rover export: DJI’s current documentation describes a DJI Terra-compatible JSON mark export and a CSV results/checkpoint export. Confirm the exact files exposed by the installed DJI Enterprise app version before field deployment, especially when a project has a prescribed exchange format or coordinate convention.
The optional D-RTK 3 Survey Pole and Tripod Kit supports the physical Rover/Base setup, but equipment selection does not replace a control plan. Where legal boundaries, professional survey opinions or regulated deliverables are involved, the project team should define the role of qualified survey professionals and authoritative control before capture.
How to use Relay Mode as a communications control
Relay Mode is for a site where obstructions affect the direct communication path. DJI directs users to install the station at a high, unobstructed location, and says the station must be fixed with its top unobstructed when the relay RTK function is used. Treat the choice of location as an engineered field decision: assess line of sight, interference, mounting security, safe access, weather exposure and the consequence of a relay failure.
Relay deployment checks
- Verify current regional radio and compatibility support.
- Pair and test the exact remote-controller and aircraft configuration before mobilization.
- Select a secure elevated point with clear paths toward the controller and work area.
- Keep the station fixed if relay RTK is part of the configuration.
- Define loss-of-link, return and landing actions in the operating procedure.
Relay boundaries
- It does not provide a blanket range entitlement.
- It does not remove terrain, structure, weather or RF risk.
- It does not by itself qualify an operation for BVLOS in Canada.
- It does not make every aircraft/controller combination compatible.
- It does not replace checkpoints or accuracy validation.
An eight-stage Canadian RTK mapping workflow
This sequence is designed for traceability. Adapt it to the project specification, professional responsibilities, client requirements, site hazards and current Canadian operating rules.
Define the deliverable and tolerance
Write down the required output, coordinate reference system, vertical reference, units, accuracy reporting method, coverage, resolution, file formats and acceptance criteria. “RTK map” is not a sufficient specification.
Verify the complete system
Check the live DJI product/support pages and current manuals for the station, aircraft, controller, app, firmware, radio availability and selected mode. Run a controlled configuration test before sending a crew to a remote Canadian site.
Establish coordinate authority
Identify where the project coordinates come from and who is accountable for them. DJI states that Broadcast/Base and Relay use WGS84 by default, while Rover coordinates are determined by the RTK source. Record transformation parameters and geoid/vertical treatment where relevant, and do not silently mix a default coordinate system with a projected client grid.
Measure control and checkpoints
Use an appropriate method and instrument for the project. If Rover Mode is selected, enter the correct pole height, observe each point carefully, separate control from independent checkpoints, and preserve the field evidence.
Configure the field mode
Use Broadcast/Base for aircraft corrections or Relay for a validated obstruction problem. Secure the station, confirm its coordinate and status, record setup details, and brief the crew on mode-specific failure actions.
Capture and perform field QA
Monitor RTK and communication status, coverage, overlap, lighting, wind, battery margins and data completeness. Review images and mission logs while a return to the site is still practical.
Process, use PPK when justified and document choices
DJI’s support documentation checked July 29, 2026 says raw satellite observation DAT files from Broadcast/Base or Relay sessions can be imported into DJI Terra 4.4.0 or later for PPK. Confirm the current minimum version before deployment. PPK is a processing option, not an automatic repair: valid timing, observation records, station coordinates and a supported software workflow are still required.
Validate and archive
Compare the finished product against checkpoints that were not used to fit the model. Report the validation method and residuals in the form the project requires, then archive source images, control, observations, processing settings, software versions and the final QA record.
PPK, checkpoints and the accuracy claim
RTK and PPK answer a positioning question; they do not answer every question about the finished deliverable. A reliable workflow keeps the acquisition record, correction observations, camera data, processing report and independent validation connected.
If a correction link drops or the real-time result is questionable, preserved raw observations may allow an approved PPK workflow. The decision should be based on data completeness and the project tolerance. Never write “survey-grade,” “centimetre accurate” or a similar result claim solely because the station, aircraft or app displayed a particular status. Report what was tested, how it was tested and against which independent reference.
Compatibility verification before purchase or deployment
DJI updates supported products and software over time, so a static aircraft list in a blog can become unsafe. Use this verification path for each project:
Confirm on official live sources
- Exact D-RTK 3 model and regional availability.
- Aircraft and remote controller support for the intended mode.
- Required DJI application, firmware and activation path.
- Current frequency limitations and site conditions.
- Current DJI Terra import and PPK support.
Validate as one field system
- Update and activate in a controlled environment.
- Connect the intended station, controller, aircraft and mobile device.
- Test the selected mode and export path with sample data.
- Confirm coordinate handling from field app to final software.
- Record the tested versions in the project configuration.
Canadian teams planning a new system can review SpeedyDrone’s surveying and mapping solutions, compare current DJI Terra options, or contact SpeedyDrone with the required deliverable, aircraft/controller configuration and field conditions.
Who should consider D-RTK 3?
Mapping teams
Teams that want one DJI station to fill distinct base and rover roles, with an auditable path into the DJI Terra ecosystem, may gain operational consistency—provided they build coordinate control and independent QA around it.
Obstructed sites
Construction, industrial or terrain-constrained sites may benefit from a tested Relay configuration when direct communications are blocked. The site still needs a safe elevated mounting position and an operating plan that complies with current requirements.
Multi-crew programmes
Organizations standardizing field records across several crews may value a common station and export workflow. The bigger benefit comes from standardized templates, version control, training, QA and accountable project handoff—not from hardware alone.
Build the complete field kit: station; suitable pole and tripod; stable mounting and safety controls; power plan; markers or targets; data storage; documented coordinate source; an appropriate control method; supported processing software; and a crew trained to recognize bad observations. Cold, remote connectivity, multipath around metal or buildings, site access and RF conditions can all affect a Canadian deployment.
DJI D-RTK 3 workflow FAQ
What is the difference between Broadcast/Base, Rover and Relay modes?
Broadcast/Base provides correction data to compatible DJI aircraft; Rover is a handheld tool for measuring control points and checkpoints; Relay bridges communications around obstructions. They solve different problems, so select the mode around the task rather than treating them as interchangeable.
Is Broadcast Mode the same as Base Station Mode on D-RTK 3?
DJI’s current web support material uses “Broadcast Mode,” while its specifications, user manual and release notes also use “Base Station Mode.” In this guide, Broadcast/Base refers to the same correction-broadcasting function.
Can one D-RTK 3 use Broadcast, Rover and Relay modes at the same time?
DJI documents one selected operating mode per station. A team may switch the same unit between modes; current 1+N workflows use separate base and rover stations, not one station running all three modes at once.
Does Relay Mode let me legally fly BVLOS in Canada?
No. Relay Mode only changes the communications path; it does not by itself qualify an operation for BVLOS. In Canada, lower-risk BVLOS must meet the applicable Level 1 Complex requirements, while operations outside those rules may require an SFOC-RPAS. Confirm the current Transport Canada category for the mission.
Does D-RTK 3 remove the need for control points or checkpoints?
No. RTK positioning does not by itself prove finished accuracy. Use independently surveyed checkpoints when accuracy must be demonstrated, and set the control plan according to the project specification, coordinate requirements, site conditions and client acceptance criteria.
Can Rover Mode export control points to DJI Terra?
DJI’s current documentation describes a DJI Terra-compatible JSON mark export and a CSV results/checkpoint export. Confirm the exact files exposed by the installed DJI Enterprise app version before field deployment.
Can Broadcast or Relay observation files be used for PPK?
DJI’s support documentation checked July 29, 2026 says raw satellite observation DAT files created in Broadcast/Base or Relay Mode can be imported into DJI Terra 4.4.0 or later for PPK. Confirm the current minimum version, preserve matching mission times and validated station coordinates, and do not assume that running PPK automatically improves a result.
How do I verify D-RTK 3 compatibility before purchase or deployment?
Check the live DJI D-RTK 3 product and support pages and current manuals for the exact regional station, aircraft, remote controller, app, firmware, mode and frequency requirements. Then validate the complete configuration before the crew travels.
