DJI D-RTK 3 - GNSS mobile station

Base station mode (transmit mode) and relay station mode

Base station accuracy:
Single point accuracy (uncalibrated):
Horizontal: 1.5 m (RMS)
Vertical: 3.0 m (RMS)

Satellite-based differential accuracy:
Convergence time: 20 min
Horizontal: 30 cm (RMS)
Vertical: 40 cm (RMS)

RTK network calibration**:
Horizontal: 1.0 cm (RMS) + 1 ppm
Vertical: 3.0 cm (RMS) + 1 ppm

Receiving station mode*

RTK accuracy (fixed measurement):
Horizontal: 0.8 cm (RMS) + 1 ppm
Vertical: 1.5 cm (RMS) + 1 ppm

RTK accuracy (tilt measurement)***:
Angle range: 0° to 60°
Horizontal: 8 mm + 0.7 mm/° tilt (accuracy <2 cm within 30°)

* The accuracy of measurement depends on various factors. This value is obtained under normal conditions with undisturbed visibility, good satellite distribution, low ionospheric activity and no electromagnetic interference or multi-path effects.
** The accuracy of base station calibration coordinates depends on various factors. For surveying, precise flight paths, etc., it is recommended to calibrate during periods of inactive ionosphere, in an open, undisturbed environment without electromagnetic interference or multipath effects, using four or more GNSS systems.
*** Intense vibration and rapid rotation may affect the accuracy of the inertial measurement unit.

Supported frequencies: BDS B2b, GALILEO E6**, L-BAND**
Convergence time: 20 minutes
Horizontal: 30 cm (RMS)
Vertical: 40 cm (RMS)

* The accuracy of the measurement depends on various factors. This value is obtained under normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity and no electromagnetic interference or multi-path effects.
** Will be supported in later versions.

When used as a base station or relay station, it records raw RTCM 3.2 observation data in DAT format.
In rover station mode or calibration mode for base and relay stations:
1. Supports RTCM v3.0, v3.1, v3.2, v3.3, MSM4, MSM5, MSM6, MSM7 protocols.
2. It is recommended to use receivers that support four or more GNSS systems.

Measured in an undisturbed outdoor environment free of interference. The above figures show the farthest communication range for one-way flights without return under each standard. Always pay attention to the RTH reminders in the app when flying.

FCC
Between the drone and the relay station: 25 km
Between the relay station and the remote control apparatus: 1 km

SRRC
Between drone and relay station: 12 km
Between relay station and remote control apparatus: 1 km

CE
Between drone and relay station: 10 km
Between relay station and remote control apparatus: 300 m

Measured in an undisturbed outdoor environment free of interference. The above figures show the farthest communication range for one-way flights without return under each standard. Always pay attention to the RTH reminders in the application when flying. The relay station should be placed on an elevated position without obstructions to ensure clear communication between the remote control apparatus and the drone.

Strong interference: City centers, approximately 1.5-5 km
Medium interference: Suburban areas, about 5-15 km
Micro interference: Remote/peripheral areas, approx. 15-25 km

Data is tested in accordance with FCC standards in an undisturbed environment with typical interference. They are for reference only and are not a guarantee as to actual flight distance.

Low interference and building obstacles: about 0-0.5 km
Low interference and obstacles in the form of trees: about 0.5-3 km

Data is tested in accordance with FCC standards in an undisturbed environment with typical interference. They are for reference only and are not a guarantee as to actual flight distance.

OcuSync 4 directional antennas × 4, 2T4R

The antenna uses a standard SMA connector with reverse polarity.

USB PD 3.0 protocol, 9V to 15V adapter output voltage (e.g., portable charger DJI 65W)

When using a non-recommended charger, such as a charger with a 5V output, the D-RTK 3 can only be charged when the power is turned off.

USB Type-C

Relay station: 4 hrs.
Base station: 7 hours
Rover Station mode: 10 hrs.

* Battery performance may drop at low temperatures; it is recommended to use power supplies that support USB PD 3.0.

LiPo
Capacity: 6500 mAh
Energy: 46.8 Wh

-20° to 55°C

1. In a normal temperature environment, charging power will be reduced if the temperature of the device case exceeds 48°C. Charging at full power will resume after cooling down.
2. After storage/use at low temperatures, the unit should be moved to a normal temperature environment and allowed to warm to the internal temperature of the battery>0°C before charging.
3. After storage/use at high temperatures, the unit should be moved to a normal temperature environment and allowed to cool down until the internal temperature of the battery reaches <45°C before charging.

IP67*

* Ensure that all rubber plugs on the housing are properly installed.
