D-RTK is a high-precision navigation and positioning system that integrates advanced software algorithms with a GPS+BDS or GPS+ GLONASS dual-band, four-frequency receiver. The D-RTK system is compatible with a range of airframes, and gives the equipped system centimeter-level positioning accuracy both horizontally and vertically.
Yes. But when mounted on a Matrice 600, positions for the two systems overlap. You will need to adjust the mounting position for one or both of the devices to uses them simultaneously.
Yes. When conditions are not ideal for the D-RTK, the A3 will shift to GPS mode to maintain flight safety.
Yes. To do so, the antenna must be mounted in the Master antenna position. When used with a single antenna, the D-RTK system will only be able to provide positioning information but no heading information.
When the Air System and Ground System are within a 10km distance from each other, their absolute positioning accuracy will depend on the accuracy of the Ground Systems satellite-based positioning.
The relative positioning accuracy between the Air System and Ground system is down to the centimeter-level.
The D-RTK’s Difference Tec functionality triangulates the absolute and relative positions of each system to reach a final absolute accuracy of 2cm.
For navigation, the D-RTK will calculate the position vector from the Master antenna to the Slave antenna to accurately determine its direction.
Yes. The two processors are identical and interchangeable.
Yes. Remember to connect the antennas to DJI Assistant 2 and configure antenna offset parameters after switching places.
Yes. Use D-RTK in open areas, unobstructed and free of interference.
Connect the D-RTK processors to DJI Assistant 2, install the latest firmware, and configure the antenna offset parameters for your system.
Measure the distance between the gravitational center and the center of the antennas and enter that as the offset parameter.
The GPS module will take over positioning and navigation, and the system will continue to function as before.
Yes, but in this scenario the system will fall back to GPS positioning only. If signal strength increases during flight, D-RTK will take over.
If the D-RTK is not able to receive the signal it needs for its full functionality, the system will fall back to GPS positioning and compass for heading.
No. But you need to purchase the tripod mount for the Ground System separately.
A single 3S-12S (12V-52V) battery, available with or without intelligent functions, provides power to the system.
No. However, you will need to reconfigure its antenna offset parameters to reflect the change in positions.
The D-RTK has a mechanism to prevent accidents caused by repositioning Ground System. If the Ground System is moved within a short distance, the aircraft will follow. If it’s moved more than 50m away from its original position, the Ground System will update its location, while the aircraft hovers while waiting for its new position.
The D-RTK’s maximum transmission is dependent on that of the DATALINK PRO
For temporary loss of signal, D-RTK will enter Calculation Mode to triangulate its position and retain its accuracy. If signal is lost for more than 10 seconds, D-RTK will exit Calculation Mode and fall back to GPS positioning and switch to the previous flight mode.
