D-RTK 3 Multifunctional Station Agri Bundle
£1,329.00
- Centimetre-level farm accuracy: Power Mavic 3 Multispectral surveys and DJI Agras spray lines with reliable RTK, even where mobile data is weak.
- Three tools in one: Use as a Base for field corrections, a Rover for GCPs/check points, or a Relay to assist link range.
- Rugged & field-ready: Weather-sealed (IP67), multi-hour battery life, and USB-C PD charging for all-day operation on UK farms.
- Repeatable results: Consistent, cm-grade geotags improve NDVI/NDRE analysis and make boundaries/headlands easy to re-fly each season.
D-RTK 3 Multifunctional Station — RTK for UK Agriculture & Multispectral Mapping
The D-RTK 3 Multifunctional Station is DJI’s field RTK base/rover/relay that delivers
centimetre-level positioning for Mavic 3 Multispectral (M3M) crop surveys and
DJI Agras spraying/spreading missions. Use it to capture accurately geotagged imagery, repeat routes
across seasons, and tighten boundaries and headlands when operating in rural areas with patchy mobile coverage.
Base Station (Field RTK)
Broadcasts RTK corrections to supported DJI aircraft for on-the-spot cm-level positioning during mapping and operations.
Rover (GCPs & Check Points)
Use on a survey pole to collect ground control/check points for QA and PPK—ideal when you want audit trails or absolute accuracy.
Relay (Signal Bypass)
Mount high (yard mast or field edge) to help overcome hedges/buildings and keep links robust during missions.
Why it matters on UK farms
- Reliable accuracy without NTRIP: Run your own base when mobile data is weak or unavailable, keeping surveys and spray lines on spec.
- Better agronomy decisions: Cm-grade geotags improve index consistency (NDVI/NDRE) and variability analysis for Mavic 3M.
- Repeatable operations: Re-fly boundaries, tramlines and headlands precisely—useful for Agras spraying/spreading season to season.
- Fast to deploy: Tripod/pole kit with quick height lock; USB-C PD charging for easy power on farm or in the yard.
At-a-glance highlights
- Multi-mode: Base, Rover, or Relay in one unit.
- Rugged build: Weather-sealed to IP67 with operating range around −20 °C to 55 °C (field station).
- Endurance: Up to ~7 hrs (Base), ~10 hrs (Rover), ~4 hrs (Relay) per charge.
- Tight ecosystem: Works with Mavic 3 Enterprise series (incl. M3M) and Agras workflows via DJI Pilot 2 / Enterprise App.
D-RTK 3 Multifunctional Station — FAQ (UK Agriculture)
Does D-RTK 3 work with the Mavic 3 Multispectral (M3M)?
Yes. Use D-RTK 3 as a local RTK base with M3M via the Enterprise (Pilot 2) workflow. It delivers centimetre-level positioning for crop-mapping and scouting.
Is D-RTK 3 useful for DJI Agras spraying/spreading (e.g., T50/T40/T25)?
Yes. A local base improves boundary accuracy, repeatable headlands and line tracking across seasons, especially where mobile data for NTRIP is weak.
Do I still need NTRIP if I buy D-RTK 3?
No — D-RTK 3 replaces the need for network corrections on sites with poor data coverage. If you have reliable 4G/5G, NTRIP remains a simple option. Many farms keep D-RTK 3 for no-signal areas and repeatable local control.
How accurate is it for farm mapping?
With a good sky view and stable corrections, expect centimetre-level horizontal accuracy. Always validate with a few check points, particularly for compliance or research work.
Do I still need ground control points (GCPs)?
For most agronomy tasks, RTK + a few check points is sufficient. For survey-grade deliverables or audits, GCPs/check points are recommended per your specification.
What’s the best way to set up D-RTK 3 in a field?
Mount on the tripod or survey pole over firm, level ground with a clear sky view. Avoid metal roofs, tree canopies and hedges that cause multipath. Record the antenna height and keep the setup stable during flights.
How do I enter coordinates — known point or “survey-in”?
Use a known control point when available (fastest and most repeatable). Otherwise, use the built-in survey-in/average method to initialise the base before missions.
Can one D-RTK 3 serve multiple drones?
Yes. A single base can provide corrections to multiple supported DJI aircraft within range and line-of-sight. Plan your airspace and task timings accordingly.
What is the runtime and how do I power it all day?
Typical battery endurance is several hours (mode-dependent). For long days, bring a USB-C PD supply or charge between blocks; many teams power from a vehicle or field generator at the headland.
Is D-RTK 3 weatherproof for UK conditions?
The unit is weather-sealed (IP-rated) and built for outdoor work. Still avoid immersion and wipe down after rain or dust; keep ports capped when not in use.
Does D-RTK 3 change UK CAA rules or reduce VLOS requirements?
No. RTK improves positioning accuracy but does not alter CAA rules. Maintain VLOS and operate within your Operational Authorisation and site safety assessment.
Which coordinate systems should I use — OSGB36 (BNG) or WGS84?
Flights/geotags are typically WGS84. If you need OSGB36/BNG for farm GIS, convert in DJI Terra or your GIS package. Record base coordinates and antenna height for consistent transformations.
Can I use D-RTK 3 as a rover for GCPs and check points?
Yes. Fit to a survey pole in rover mode to capture GCPs/check points for QA, trials or regulatory documentation.
What if my fields are surrounded by trees or steep hedgerows?
Place the base on higher ground with a clear horizon. If link quality is impacted by terrain/obstacles, reposition the base or the pilot to maintain robust connections.
Will D-RTK 3 help variable-rate prescriptions from M3M data?
Indirectly, yes. Better absolute and relative positioning improves map alignment and seasonal repeatability, which supports more reliable zone maps and prescriptions.
What’s included and what else do I need?
The station ships ready to use; with tripod for stable mounting. Many UK users also carry a USB-C PD charger, stake/weights for the tripod, and a notepad for antenna heights/coordinates.
Any UK-specific tips before I start mapping or spraying?
Check airspace/landowner permissions, set safe take-off/landing areas, brief helpers, and capture a couple of check points. For Agras work, align boundaries/headlands with RTK then run a short test pass to verify rates and overlap.
