Optimized precision - Ultimate reliability
D-RTK is a high-precision navigation and positioning system specially developed for the DJI A3 flight controller models.
Thanks to the dynamic differential technology, 3D positioning with centimetre precision can be achieved.
The positioning accuracy of the D-RTK is higher than with conventional barometers, compasses and GPS systems.
This makes D-RTK an important component for commercial, industrial and scientific applications where precision is required.
positioning accuracy
Precise positioning of one centimetre horizontally and vertically is made possible by the dynamic differential technology.
This precision makes it possible to develop repeatable flight routes.
The reliable and valuable visual data generated are indispensable for commercial and industrial applications.
height accuracy
Although barometers are often used for positioning unmanned aircrafts, they can exhibit discrepancies in the event of air flow fluctuations, such as during take-off, braking or after long flight times.
This has a negative effect on flight performance and complicates the workflow due to data deviations.
The precise height calculations eliminate the deviations by minimizing them to only one centimeter.
This means that professionals can fully rely on the accuracy of the data.
Exact flight direction reference
The flight direction reference, which becomes significantly more accurate with the two antennas, cannot be achieved with a single compass sensor.
By removing the compass, the system is no longer susceptible to magnetic interference.
This makes it easy to fly near metal structures and high-voltage power lines, while other aircraft cannot function there.
Positioning accuracy (horizontal): 1 cm + 1 ppm
Positioning accuracy (vertical): 2 cm + 1 ppm
Comprehensive applications
D-RTK was developed especially for the A3 flight controllers and works via the wireless DATALINK PRO connection.
In this way, comprehensive applications are made available to a large number of industries.
D-RTK supports the DJI GO App and the DJI Assistant 2.
This enables a seamless connection to the ground station for accurate and repeatable flights.
This makes the system ideal for scientific investigations, airspace inspections and agriculture.
Multiple data transfer modes
Three data transfer modes are supported:
Full Duplex, Broadcast and Ground Station.
In full duplex mode, bidirectional data transmission between a base station and a mobile station can be established.
In broadcast mode, data can be transmitted simultaneously from one base station to up to 32 mobile stations.
In Ground Station mode, RTK data can be transmitted bidirectionally from one base station to up to five mobile stations.
Multiple connections
The Datalink Pro has several connections: USB, CAN and UART.
It can also be used with custom-built aircraft.
The connections can be selected with a toggle switch and the data is automatically transferred from one connection to another.
Scope of delivery: 1x D-RTK GNSS, 1x Datalink PRO
