DJI has built the Matrice 30 series to be a powerful but compact workhorse for enterprise and commercial businesses. As a part of this M30 and M30T is designed with redundancy in mind, allowing operations to continue in the event one system was to fail.
Redundant flight systems
Inertial measurement units
Martice 30 and Matrice 30T are equipped with dual IMUs ensuring data continues to be recorded in the case one was to fail. DJI's algorithms can detect the likelihood of faults and will automatically switch to the backup IMU.
Barometers
The dual barometers found on the Matrice 30 series ensures the aircraft's altitude readings continue to work if one was to fail mid-flight.
RTK antennas & GNSS modules
Matrice 30 and Matrice 30T both feature dual RTK antennas and dual GNSS modules, ensuring the altitude positioning and centimetre level accuracy are maintained in case one of each of the systems were to fail.
Compass
The dual compass setup of the Matrice 30 series ensures the aircraft continues on the right flight path even if one was to fail during an operation. The RTK modules are also backed up in the case that they are blocked.
Vision sensors
The M30 series features six pairs of vision sensors which are mainly used for obstacle avoidance in ideal lighting conditions. The vision sensors are used in conjunction with the infrared ToF sensors mentioned in the next section.
Infrared ToF sensors
The Matrice 30 series also uses six infrared time of flight (ToF) on all six sides allowing accurate distance measurements to be taken in low-light and night conditions and for obstacle avoidance.
Control signal
The communication link between the flight control system and motor speed controllers (ESCs) use both peripheral interface (SPI) and asynchronous receiver-transmitter (UART) to ensure there is no loss of communication.
Batteries
The Matrice 30 series uses a dual battery design, which allows the aircraft to continue flying even if one battery were to fail mid-flight.
Transmission links
The Marice 30 uses four antennas for the best possible connection but can be controlled via one in the case the other three failed for whatever reason. M30 series also uses both the 2.4Ghz and 5Ghz bands for automatic switching when interference is detected. Both DJI's OcuSync 3 Enterprise and a 4G network can be used to maintain control.
Remote controllers
The M30 series can be used in dual controller mode, meaning if the main controller loses connection to the drone the second one will automatically connect and ensure the pilot has full control over the drone.
Other safety systems
Emergency landing
Just like its bigger sibling, the Matrice 30 series has a three-motor emergency landing mode that activates in the unlikely event a motor or propeller fails during an operation. While in this mode, ascending, descending, and horizontal movements can be made by the pilot to safely bring the drone down.
ADS-B receiver
Matrice 30 and Matrice 30T are equipped with an ADS-B receiver. This allows crewed aircraft up to 20km away to be detected using DJI's AirSene technology. This information, including the position, altitude, heading, and velocity are shared with the pilot via the DJI Pilot app.
