DJI D-RTK 3 Multifunctional Station
W-9 and vendor pack with every quote
Shipped direct from the manufacturer
Base station, relay station and survey rover in one unit, about 1.26 kg. Base Station Mode serves DJI's long supported models list, Relay Station Mode serves six aircraft. Rover accuracy is 0.8 cm + 1 ppm horizontal, RMS, under DJI's own conditions. No pole, tripod or power adapter is included.
01
The mode decides which aircraft this station serves, and the relay list is far shorter than the base list
A base station is a ground receiver broadcasting corrections to an aircraft in flight. In Base Station Mode DJI's list is long: the Matrice 400, the 4E, 4T, 4D and 4TD, the 3D and 3TD. It also names the Matrice 300 and 350 RTK, the Matrice 30 Series, the Mavic 3 Enterprise Series and the DJI FlyCart 100. Agriculture and filmmaking add the Agras T60, T50, T25, T40 and T20P, the FlyCart 30 and the Inspire 3. Relay Station Mode collapses that to six: the Matrice 400, 4E, 4T, 4D, 4TD and the FlyCart 100. DJI states relay mode is unavailable in countries without 5 GHz support, naming Japan, Russia and Kazakhstan. DJI footnotes most of the base list, where only manual D-RTK 3 position calibration is supported today. There the station's coordinate has to be in hand first. The Matrice 400, the Matrice 4 Series and the FlyCart 100 carry no footnote.
02
Other D-RTK 3 units exist, and the one that relays for a DJI Dock 3 is not this one
Relay for a DJI Dock 3 is a different product, the D-RTK 3 Relay Fixed Deployment Version, with a PoE port and a fixed mount. DJI states that version does relay station mode only, with DJI Dock 3 and Matrice 4D Series aircraft. If the job is a permanent relay beside a dock, this station is the wrong purchase. A D-RTK 3 AG also exists, which DJI states supports Broadcast Mode only. This unit is the portable one that does all three jobs.
03
Set down on an unsurveyed point, the station knows its own position to 1.5 m, not to a centimeter
Uncalibrated, DJI's single point figure is 1.5 m horizontal and 3.0 m vertical, both RMS, a statistical average rather than a worst case. Network RTK calibration brings the station's own coordinate to 1.0 cm + 1 ppm horizontal and 3.0 cm + 1 ppm vertical, RMS. DJI conditions that on an inactive ionosphere, open ground with no electromagnetic interference or multipath, and four or more GNSS systems. Multipath is signal arriving by reflection. DJI's known issue list warns Custom Network RTK calibration can leave systematic deviations in mapping results in some scenarios. DJI's own workaround is manual calibration from coordinates obtained in advance. DJI measured the Zenmuse L3's published accuracy in its own laboratory, against a position calibrated D-RTK 3.
04
On a pole it is a survey rover, rated 0.8 cm plus 1 ppm horizontal under DJI's stated conditions
It pairs over Bluetooth 5.1 with one Android device running the DJI Enterprise app, within 30 m. DJI states the app needs Android 10 or later, and publishes a tested phone list. Fixed survey accuracy is 0.8 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical, RMS. DJI's condition is an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath. Tilt survey runs to 60 degrees, and DJI cautions that intense vibration and rapid rotation affect the inertial measurement unit. DJI's known issue list reports that collecting ground control points in rover mode may cause systematic deviations in certain areas or periods. It advises avoiding high ionospheric activity for that work.
05
40 km belongs to base station mode and one aircraft, and DJI publishes two different relay ranges
The 40 km figure is Base Station Mode to a Matrice 400 under FCC, falling to 20 km under SRRC, CE and JP. For every other DJI aircraft it is 15 km FCC, 12 km SRRC, and 8 km CE and JP. DJI measured those outdoors, unobstructed and free of interference, on flights that did not return. Relay Station Mode is where DJI disagrees with itself. DJI's specification page gives 25 km FCC, 12 km SRRC and 10 km CE. DJI's own store listing gives 15 km, 12 km and 8 km, under the same unobstructed condition. Only the SRRC figure agrees, so call before you plan a corridor around either.
06
No pole, no tripod and no power adapter are included, and the station cannot be moved once it is broadcasting
DJI's own packing list is short: the station, four spare OcuSync directional antennas and one USB-A to USB-C cable. The base takes a 5/8 inch 11 UNC thread, the standard pole and tripod fitting, and DJI sells both separately. Charging needs a USB PD 3.0 adapter putting out 9 V to 15 V, and none is included. Once broadcasting it watches its own position: move it and the app raises a displacement warning, the mission is terminated, and the pilot lands manually. Call and we will add a pole, tripod or adapter to the same order.
07 FOR UNIVERSITIES, COLLEGES AND GOVERNMENT AGENCIES
Who should not buy this station, and how to order it if you should
Fly no aircraft from DJI's supported models list and two of the three modes are dead weight, though rover mode still works alone. DJI's specification page rates this station -20 to 55 degrees C. DJI's own user guide gives -30 to 55 degrees C for the same model, with a charger connected below -20 degrees C. The two disagree, so call if the work is genuinely that cold. DJI publishes no charging time on its product page, its specification page, its FAQ, its user manual or its user guide. The number to quote on a purchase order is CP.EN.00000551.01. Call +1 888 850 6533, Monday to Friday, 9 am to 5 pm Mountain Time. A specialist will confirm the mode and the aircraft against your work.

Specifications
Which aircraft this station serves, and in which mode
| Base Station Mode, enterprise aircraft | DJI's own supported-models list names the Matrice 400, the Matrice 4E and Matrice 4T, the Matrice 4D and Matrice 4TD (with the DJI RC Plus 2 Enterprise), the Matrice 3D and 3TD (with the DJI RC Pro Enterprise), the Matrice 300 and 350 RTK, the Matrice 30 Series, the Mavic 3 Enterprise Series, and the DJI FlyCart 100DJI marks the Matrice 3D and 3TD, Matrice 300 and 350 RTK, the Matrice 30 Series and the Mavic 3 Enterprise Series with a footnote reading that only manual D-RTK 3 position calibration is currently supported, and pointing to official updates for future changes. On those aircraft you need the station's coordinate in hand before you start. The Matrice 400, Matrice 4 Series and DJI FlyCart 100 carry no such footnote |
| Base Station Mode, agriculture and filmmaking aircraft | DJI's same list names the Agras T60, T50, T25, T40 and T20P, the DJI FlyCart 30, and the DJI Inspire 3Every model in this part of DJI's list carries the same footnote: only manual D-RTK 3 position calibration is currently supported |
| Relay Station Mode | DJI's supported-models list for this station in Relay Station Mode is shorter than the base-station list. It names the DJI Matrice 400, the Matrice 4E and Matrice 4T, the Matrice 4D and Matrice 4TD (with the DJI RC Plus 2 Enterprise), and the DJI FlyCart 100DJI's FAQ states this mode is unavailable in countries or regions without 5 GHz frequency support, and names Japan, Russia and Kazakhstan as examples where only Base Station and Rover Station modes work. DJI's FAQ adds that a remote controller and relay station already paired elsewhere will not connect in those regions, and that pairing attempted there will fail |
| Rover Station Mode | No aircraft is involved. The station pairs over Bluetooth 5.1 with one Android mobile device running the DJI Enterprise app, and DJI states the app requires Android 10 or laterDJI publishes a tested phone compatibility list on its own downloads page and points buyers to it rather than stating that every Android 10 device works |
| How many devices connect at once | DJI states this station connects to multiple DJI aircraft at once in Broadcast Mode, to one remote controller and its paired aircraft in Relay Mode, and to one mobile device over Bluetooth in Rover Mode |
| A DJI Dock 3 relay is a different product | DJI's own supported-models block splits into two columns. Relay for a DJI Dock 3 sits under the D-RTK 3 Relay Fixed Deployment Version, a separate product with a PoE port and a fixed mount, and DJI's FAQ states that version supports relay station mode only and works with DJI Dock 3 and Matrice 4D Series aircraft. This station, the Multifunctional Station, is the portable one that also does base station and rover workIf the job is a permanent relay beside a DJI Dock 3, this is not the unit for it. Call before ordering and a specialist will confirm which of the two fits the deployment |
| The D-RTK 3 AG is also a different product | DJI's FAQ states the D-RTK 3 AG supports Broadcast Mode only and is compatible with a limited number of device models, where this station supports Relay Station Mode, Broadcast Mode and Rover Station ModeDJI's FAQ does not itemize which aircraft the D-RTK 3 AG supports. |
| What the Mavic 3 Enterprise Series means | DJI's supported-models list names the series rather than the individual aircraft. DJI's own Mavic 3 Enterprise Series page names the Mavic 3E and the Mavic 3TWhether DJI counts any other Mavic 3 enterprise variant inside that series for this station is not stated on either page. Call and a specialist will confirm your exact model before you order |
| Firmware has to move together | DJI states in its own known-issue list that the aircraft, the remote controller and this station must all be updated to the latest firmware version, otherwise they will not be compatible with each other |
Accuracy, with DJI's own test conditions
| Base station coordinate, uncalibrated | Single point accuracy, uncalibrated: horizontal 1.5 m (RMS), vertical 3.0 m (RMS)This is what the station knows about its own position before any calibration. It is the figure that applies if the unit is simply switched on over an unsurveyed point |
| Base station coordinate, satellite-based differential | Satellite-based differential accuracy: horizontal 30 cm (RMS), vertical 40 cm (RMS), after a 20 minute convergence time |
| Base station coordinate, Network RTK calibration | Network RTK calibration: horizontal 1.0 cm + 1 ppm (RMS), vertical 3.0 cm + 1 ppm (RMS)DJI's own condition on this figure: calibration accuracy depends on several factors, and for surveying and high-precision flight paths DJI recommends calibrating during periods of inactive ionosphere, in open unobstructed environments with no electromagnetic interference or multipath, using four or more GNSS systems |
| Three ways to set the station's coordinate | DJI's FAQ names three methods, reached through Coordinate Calibration inside the RTK settings: Network RTK calibration, PPP calibration, and manual calibrationDJI's own known-issue list, published June 2025, states that Custom Network RTK calibration can leave systematic deviations in mapping results in some scenarios, and that for high-precision aerial surveying you should obtain the base station coordinates in advance and use manual calibration instead. That is DJI's own workaround, not a general recommendation |
| Rover accuracy, fixed survey | Horizontal 0.8 cm + 1 ppm (RMS), vertical 1.5 cm + 1 ppm (RMS)DJI's stated condition: normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath effects |
| Rover accuracy, tilt survey | Angle range 0 to 60 degrees. Horizontal 8 mm + 0.7 mm per degree of tilt, with accuracy under 2 cm within 30 degreesDJI's stated condition: intense vibrations and rapid rotations can affect the accuracy of the inertial measurement unit. DJI also states in its own known-issue list that the inertial navigation system drifts over time, and that the app will prompt for recalibration by shaking the device |
| Standalone precise point positioning | Supported frequencies BeiDou B2b, Galileo E6 and L-Band. Convergence time 20 minutes, horizontal 30 cm (RMS), vertical 40 cm (RMS)DJI attaches two separate future-support notes to these bands. Its specification page marks L-Band as something that will be supported in later versions, and its FAQ states that software support for parsing the Galileo E6 band will be available in future versions. Read as a BeiDou B2b capability today with the other two bands stated as coming |
| Initialization reliability | Greater than 99.9 percent, DJI's own figure |
| What the standard deviation on screen means | DJI states that the horizontal and vertical standard deviation shown after the first fixed solution in Rover Station Mode reflects the internal consistency of the previous few epochs, and does not represent the absolute accuracy of the current RTK result |
| Collecting ground control points, DJI's own caution | DJI states in its own known-issue list that in certain areas or periods, collecting ground control points in Rover Station Mode may result in systematic deviationsDJI's own recommendation for high-precision mapping and point collection is to avoid working during periods of high ionospheric activity |
Satellite tracking
| GNSS frequency coverage | GPS L1C/A, L2C, L5. BeiDou B1I, B2I, B3I, B1C, B2a, B2b. Galileo E1, E5a, E5b, E6. GLONASS L1, L2. QZSS L1C/A, L2C, L5. L-Band supportedDJI's product page describes this as five satellite systems across nineteen frequency points. DJI's own user guide states the same coverage in shorter notation, as GPS L1, L2, L5 and QZSS L1, L2, L5 |
| Antenna | Four OcuSync 4 directional antennas, 2T4R, on standard reverse polarity SMA connectorsDJI states the antennas are removable for rover work but that prolonged removal may compromise the waterproof integrity of the antenna interfaces, so it advises removing them only when necessary |
| Antenna phase center | DJI states the station uses an air dielectric antenna with a filtering design, and that antenna phase-center accuracy is maintained within millimeter level |
The correction and video link
| Transmission system | O4 Enterprise. Operating frequencies are 2.4 GHz, 5.2 GHz and 5.8 GHz in Relay Station Mode, 2.4 GHz and 5.8 GHz in Base Station Mode, and Bluetooth 2.4 GHz in Rover Station ModeDJI states the operating frequencies allowed vary by country and region, and points to local law |
| Base Station Mode, maximum distance | Between this station and a Matrice 400: FCC 40 km, SRRC, CE and JP 20 km. Between this station and other DJI aircraft: FCC 15 km, SRRC 12 km, CE and JP 8 kmDJI's condition: measured in an unobstructed outdoor environment free of interference, showing the farthest communication range for one-way, non-return flights under each standard |
| Relay Station Mode, maximum distance | DJI's specification page states, under FCC, 25 km between the aircraft and the relay station, with the relay to remote controller or DJI Dock 3 leg recommended within 1 km and 3 km maximum. Under SRRC, 12 km and the same 1 km recommended, 3 km maximum. Under CE, 10 km, with the second leg recommended within 300 m and 1 km maximumDJI's own store listing publishes a lower set of relay figures for this mode, given in the row below. The two DJI figures disagree. |
| Relay Station Mode, DJI's second published figure | DJI's own store listing for this station states, for Relay Station Mode, 15 km between the aircraft and the relay station under FCC, 12 km under SRRC and 8 km under CE, with the relay to remote controller leg given as 1 km, 1 km and 300 mMeasured unobstructed and free of interference, DJI's own condition. Only the SRRC figure agrees with DJI's specification page. Call and a specialist will confirm which figure applies to your regulatory standard before you order |
| Relay Station Mode, siting requirement | DJI states the relay station should be deployed only after a field survey, and installed on rooftops, tower tops or other elevated, unobstructed, interference-free locations. Where the survey result reports that the site is not suitable for deploying a dock or that RTK positioning cannot be used, DJI states the site is not recommendedDJI adds that a poor site may affect relay station upgrade and log download, not only range |
| What a relay actually buys you | DJI publishes the gain as a multiple rather than a fixed distance: 3x to 5x performance improvement under severe obstruction such as buildings or mountains, and 1x to 3x under mild obstruction such as trees or glassDJI's condition: the relay station must be deployed in an elevated, unobstructed location free of interference |
| Range in real interference | DJI publishes separate unobstructed figures for interference: approximately 1.5 to 5 km in city centers, 5 to 15 km in suburban areas, and 15 to 25 km in remote areas and at the coast. Where the path is also obstructed, DJI publishes approximately 0 to 0.5 km behind buildings and 0.5 to 3 km through trees, both under low interferenceDJI's condition: tested under FCC standards, offered only as a reference, and with no guarantee as to actual flight distance |
| Rover Station Mode, maximum distance | 30 m between this station and the mobile device, over Bluetooth 5.1 at 2.400 to 2.4835 GHz |
Data formats and processing
| What it records | As a base station or relay station, this unit records RTCM 3.2 raw observation data in DAT format to internal storage. In rover station mode, and in calibration mode for base and relay stations, it supports RTCM v3.0, v3.1, v3.2, v3.3 and MSM4 through MSM7DJI recommends receivers that support four or more GNSS systems |
| Getting the raw data out | DJI states a raw observation file is generated each time the device is powered on and off in Relay Station Mode or Broadcast Mode. Connect the station to a computer over USB-C and copy the DAT files from the removable disk that appears |
| Post-processed kinematic work | DJI states raw satellite observation data from this station can be imported into DJI Terra for PPK processing in DJI Terra version 4.4.0 and above. DJI's user manual adds that third-party decoding tools can also convert the DAT files to RINEX or other formats for PPK processingDJI Terra is licensed separately and is not included with this station |
| Getting control points out of rover mode | DJI states the DJI Enterprise app exports control points for DJI Terra in JSON format and control point results in CSV, through Mission Library then Export. DJI's user manual states the JSON mark file imports into DJI Terra through GCP Management with no format selection needed |
| Coordinate systems | DJI states Relay Station Mode and Broadcast Mode use WGS84 by default. Rover Station Mode outputs latitude, longitude and altitude, with the coordinate system determined by the RTK source, and the DJI Enterprise app converts those to standard projection formats using a built-in projection database |
| Position output rate | DJI states the position output frequency is 1 Hz in Broadcast Mode and in Relay Station Mode |
Power, battery and runtime
| Battery | LiPo, 6500 mAh, 46.8 Wh, built into the station |
| Runtime by mode | Base station 7 hrs, relay station 4 hrs, rover station 10 hrsDJI's condition: measured at normal temperature. DJI states battery performance may decrease in low temperatures and recommends powering from a USB PD 3.0 adapter in that case |
| Power draw | Relay station 14.5 W, base station 7 W, rover station 6.2 WDJI's condition: these are maximum figures without heating. Connected to a USB-C supply above 9 V, DJI states maximum consumption with heating is 36.5 W |
| Charging | USB Type-C, from a USB PD 3.0 adapter with an output voltage of 9 V to 15 V. DJI names its own 65 W Portable Charger as an example of a suitable adapterDJI states a non-recommended charger such as a 5 V output can only charge this station while it is powered off. No power adapter appears on DJI's own in-the-box list for this station |
| Charging temperature limits | DJI states charging power is limited if the shell temperature exceeds 48 degrees C (118.4 degrees F), and resumes at full power after cooling. After cold storage or use, the internal battery must warm above 0 degrees C (32 degrees F) before charging. After hot storage or use, it must cool below 45 degrees C (113 degrees F) before charging |
| First power on | DJI states the internal battery has to be activated by charging before first use, and that the station should be charged until the indicator shows green before it is used |
| Charging time | DJI publishes no charging time for this station on its product page, its specification page, its FAQ, its user manual or its user guide |
| Ethernet | Not supported on this station. DJI publishes an Ethernet requirement only for the separate D-RTK 3 Relay Fixed Deployment Version |
Build, environment and mounting
| Weight and dimensions | Approximately 1.26 kg (2.78 lbs). 163 mm by 89 mm, without the OcuSync directional antennas fitted |
| Protection rating | IP67DJI's condition: measured in a controlled environment, not permanently effective, and liable to decrease through wear and tear, with all rubber port covers properly installed |
| What the protection rating covers | DJI's own store listing states the IP67 rating is for the station onlyA pole and tripod bought to carry it are rated separately or not at all |
| Operating temperature | DJI's specification page gives -20 to 55 degrees C (-4 to 131 degrees F) for this stationDJI's own user guide gives a different figure for the same model, R600BS: -30 to 55 degrees C, with a footnote that a compatible PD charger must be connected to power the station on below -20 degrees C. The two DJI documents disagree. If the work is genuinely below -20 degrees C, call and a specialist will confirm the position with DJI before you order |
| Altitude and drop | Maximum operating altitude 6000 m. Drop resistance 2 m with the pole fitted |
| Mounting thread | A 5/8 inch 11 UNC threaded hole in the base, the standard survey pole and tripod thread |
| Survey pole and tripod | Sold separately by DJI as a Self-locking Survey Pole and a Dual-lock Tripod. DJI gives the pole a diameter of 32 millimeters and a length of 1.25 to 2 meters, and the tripod a height of 92 millimetersNeither is included with this station. Call and we will add a pole and tripod to the same purchase order |
| Manufacturer model number | R600BS, from the regulatory notice inside DJI's own user guide for this station |
| Order part number | CP.EN.00000551.01DJI publishes no order part number for this station on its product page, its specification page, its FAQ, its downloads page, its user manual, its user guide or its own store listing. It is the number to quote on a purchase order |
| Antenna replacement | DJI specifies a 13 mm open-ended wrench for installing and removing the OcuSync antennas, and states the rubber sleeve goes onto the antenna connector before the antenna goes onto the stationDJI publishes two different tightening figures for this. Its FAQ states a torque of 15 kgf and its user manual diagram states 15 kgf-cm. The two DJI documents disagree. |
| The reserved port | DJI states the reserved port currently supports no additional functions, is not detachable, and should not be opened, as opening it may affect the warranty |
Setting up in the field, DJI's own requirements
| Sky view | DJI requires no obstructions such as trees or buildings within the zone more than 15 degrees above the horizontal plane of the antennas, to stop GNSS signals being absorbed or blocked |
| Distance from interference | DJI states the setup location should be at least 200 m from high-power radio emission sources such as television and microwave stations, and at least 50 m from high voltage transmission lines. DJI also states to keep away from large areas of water and other strong reflectors to reduce multipath |
| The station cannot be moved once it is working | DJI states this station monitors its own position for movement while acting as a base station. If movement is detected, a displacement warning appears in the app, the flight mission is terminated, and the pilot has to return and land the aircraft manually. Normal operation resumes only once the station's position is updated |
| Leveling | DJI states the top of the station should be relatively level with the horizontal surface during installation, and that the tripod position and angle must not be changed after leveling without readjusting |
| Safety cautions DJI publishes | DJI states: handle the sharp ends of the survey pole and tripod with caution; when raising the station on a pole, watch the surroundings to prevent toppling or electrical hazards; take water-resistant measures and watch for lightning in rain or snow; do not obstruct the antennas in use; use only genuine or officially authorized parts; and do not disassemble the product, or the battery may leak, catch fire or explode |
| Storage | DJI recommends storing this station between -5 and 30 degrees C (23 and 86 degrees F) for periods longer than three months, at a charge level of 30 to 50 percent, in a dry environment with the ports covered and the antennas left fitted. DJI states to charge it fully at least every six months and not to store it fully discharged |
| Passwords | DJI states the default password for base station and relay station access is 123456, that password changes are not synchronized between the two modes, and that a hold of the power button resets itDJI publishes two different hold times for the reset. Its FAQ and its user manual both state 10 seconds for the base station administrator password, and its FAQ states 8 seconds for the relay station access password |
| Firmware and logs | DJI states only Relay Station Mode can update firmware or export logs through DJI Pilot 2. All three modes can do both through DJI Assistant 2 (Enterprise Series) over a USB-C cable |
| Firmware currency | DJI's release notes for this station are dated 16 June 2026, at station firmware v17.01.05.02, alongside Matrice 4 Series firmware v17.02.05.01, DJI Pilot 2 v17.2.5, DJI Assistant 2 v2.1.20 and DJI Enterprise app v2.6.0DJI states in the same document that the dock, aircraft, remote controller and station firmware must all be brought to the latest version or usage will be affected |
| Documentation DJI publishes | DJI's downloads page for this station carries a user manual in English, Dutch and Portuguese, a user guide, release notes, a known issue list and an error code lookup table. It carries no standalone safety guidelines or product information document of the kind DJI publishes for its aircraftThe safety cautions on this page are therefore taken from the notices and storage sections of DJI's own user manual, which is the most detailed caution set DJI publishes for this device |
Ordering
| Aircraft carried on this store that this station serves | The DJI Matrice 400, Matrice 4E, Matrice 4T, Matrice 4D and Matrice 4TD are each available on this store, and all five appear on DJI's supported-models list for both Base Station Mode and Relay Station Mode |
| How DJI measures Zenmuse L3 accuracy | DJI's own Zenmuse L3 specification page states that its published accuracy figures were measured in a DJI laboratory environment with a DJI Matrice 400 linked to a position-calibrated D-RTK 3 Multifunctional StationDJI's same page lists the DAT files this station records in Base Station Mode among the satellite observation formats DJI Terra accepts for PPK |
| Buying this with a LiDAR system | The Matrice 400 and Zenmuse L3 system is available on this store and treats this station as an explicit component rather than an accessory |
