DJI Matrice 350 RTK

The successor to the DJI Matrice 300RTK which is mainly used for the needs of the integrated rescue system. Carrying DJI H20T or P1 payload and LED spotlight, it is capable of monitoring the required area for 45 minutes. The IP55 rating allows it to fly even in very harsh conditions for UAV operation. It is possible to equip the DJI Matrice 350 with up to three payloads, but as standard we use “only” the DJI H20T and P1 in combination with different spotlights.

Compared to its predecessor it has a number of improvements:

  • Extended battery life: The TB60 batteries in the M300 have a lifetime of 200 charge cycles. The TB65 batteries used in the M350, have a lifetime of 400 charge cycles, double that of its predecessor.
  • Higher ingress protection rating: The M350 has an IP55 rating and offers better protection from rain and dust compared to the M300’s IP45.
  • Improved FPV camera: The M350 FPV camera now offers night vision and 1080p image resolution. The predecessor had 960p resolution.
  • Arm lock indicator: The arms of both the DJI M300 and M350 must be unfolded and locked before flight. The M350 alerts you to unsecured arms with a warning on the controller, which the M300 cannot.
  • New Controller: The M350 comes factory equipped with the DJI RC Plus controller, which has improved ergonomics, a larger screen and extended battery life compared to the M300’s Smart Controller.
  • More stable and reliable signal transmission: The M350 brings an improved anti-jamming algorithm and uses DJI’s O3 Enterprise system and a total of 4 antennas for data transmission. The M300 supports DJI O2 and has two antennas.

Carried equipment

DJI Zenmuse P1

Zenmuse P1 enables accurate and efficient aerial photography for subsequent creation of 2D maps and 3D models. The camera communicates with the aircraft's control unit for real-time flight information. All this information is used to build 2D maps and 3D models. With 3 sets of batteries, the DJI M350RTK UAV can cover up to 10 km².

DJI Zenmuse L1

LiDAR laser scanner with RGB camera. Using LiDAR technology (a method of remotely measuring the distance to the object being scanned using a laser beam), we create point clouds. We then use an RGB camera to add colour to the point cloud. This gives us a very accurate 3D model of reality. Our applications include monitoring traffic accidents, scanning burnt or crumbled objects. It is also planned to be deployed in other projects such as scanning important objects for the needs of the IZS (Integrated Rescue System), where we will create a basis for simulating and planning a crisis scenario.

DJI Zenmuse H20T

The most commonly used for the need of the IZS (Integrated Rescue System). Combination of a total of 4 different sensors. But there are also plans to integrate it into our inspection system. It has an optical ZOOM camera for detailed monitoring, a thermal camera for finding fire hotspots or searching for people, a laser rangefinder for GPS targeting of important points and counting their distance from the UAV, and a wide-angle camera for a general overview.

GL60 Spotlight

LED spotlight to assist the IZS (Integrated Rescue System). This is the most commonly used payload at events in the dark. It was created as a replacement for the DJI Z15 Spotlight we have used so far. It now has the ability to adjust its focal length during flight. This allows us to direct the intensity of the light much more precisely on the object of interest. It is fully compatible with the DJI Matrice 210 and DJI Matrice 300.

DJI M350RTK With P1 Camera and Led Light. Thanks to IP55 It Can Fly Safely in the Rain.
Maximum flight time 55 minutes
Maximum take off weight 9,2kg
Maximum speed 23 m/s
Maximum wind resistance 12 m/s
IP rating IP55
Operating temperatures -20 °C to 50 °C
Hot-swap batteries Yes

The Matrice 350 RTK has a hot-swap battery function. Thanks to this feature we are able to replace the batteries in a moment and the UAV is on all the time. The advantage is that all systems, such as RTK and GPS, are working and we don’t have to re-initialize them.


Application for measuring the fire area

In cooperation with the Fire and Rescue Service, we serve not only as an air support, but also try to ease their work by developing software. Thus, we regularly meet…
