D-RTK is a high precision navigation and positioning system specially designed for DJI A3 series flight controllers. Using dynamic differential technology, it provides ultra-accurte, centimeter level 3D positioning. This enhanced accuracy over typical barometer, compass and GPS systems, makes D-RTK essential for commercial, industrial and scientific applications where accuracy is imperative.
Precise positioning of one centimeter vertically and horizontally is made possible through dynamic differential technology. This extreme accuracy allows for the creation of repeatable flight routes that provide reliable and valuable visual data essential for commercial and industrial scenarios.
Barometers commonly found in UAS systems may suffer from altitude discrepancies when faced with fluctuations in airflow, such as during takeoff, under braking, or after extended flying. This affects an aircraft’s flight, and introduces unwanted data variation that complicates workflows. D-RTK’s precision altitudinal calculations reduce variation to two centimeter, effectively eliminating variations, giving professionals data they can rely on.
Dual antennas create heading references that are significantly more accurate than possible with a single compass sensor. By removing compass dependence, the system is also resistant to magnetic interference, such as those generated by metal structures and high voltage power lines, allowing for accurate flight in environments where other aircraft cannot function.
Specifically designed to work with the A3 series flight controllers over DATALINK PRO wireless transmission links, D-RTK provides a comprehensive solution for a variety of industries. Support for DJI GO and DJI Assistant 2 allows seamless connection to a Ground Station for accurate, repeatable flight paths ideal for surveying, agriculture and aerial inspections.
DATALINK PRO is a highly electro-magnetic interference resistant wireless datalink that supports the DJI A3, D-RTK and Ground Station. It features a number of interfaces and work modes enabling it to be tuned for the needs of different usage scenarios.
Multiple Data Transmission Modes
Three data transmission modes are supported: Full Duplex, Broadcast and Ground Station. In Full Duplex Mode, two-way data transmission is carried out between one base station and one mobile station. In Broadcast Mode, data is simultaneously transmitted from one base station to a maximum of 32 mobile stations. In Ground Station Mode, RTK data is sent from the base station to a maximum of five mobile stations, while control data is tranmitted two-ways.
A range of ports are provided to allow for use with highly customized aircraft, including USB, CAN and UART. Ports can be individually selected by toggling a switch, and data is automatically transmitted from one port to another.
