Drone DJI Mavic 3, presented last fall, turned out to be a really successful model, and the manufacturer continues to release its new modifications. In addition to the Mavic 3 Cine version for cinematographers, the Mavic 3E and Mavic 3T industrial drones, and the “lite” version for the mass buyer of the Mavic 3 Classic, a professional drone for agriculture, the Mavic 3M with a multispectral camera, is now entering the market.
Two cameras: standard and multispectral
Like the base model, the new Mavic 3M drone features a 20MP RGB 4/3” CMOS camera with a mechanical shutter. But instead of a telephoto lens, the Mavic 3M has four 5MP cameras that can capture light with different wavelengths:
- Green (G): 560 nm ± 16 nm;
- Red (R): 650 nm ± 16 nm;
- Red edge (RE): 730 nm ± 16 nm;
- Near infrared (NIR): 860 nm ± 26 nm.
The combination of a standard and a multispectral camera in one drone will allow for high-precision aerial photography, monitoring of farmland and natural resources.
The Mavic 3M has a built-in RTK module that works with 4 global positioning systems (GPS, Galileo, BeiDou, GLONASS). With RTK enabled, the location of the drone will be determined every second with centimeter accuracy.
A 5000 mAh battery provides a flight duration of up to 43 minutes – during this time, an area of up to 200 hectares can be inspected. The maximum speed in normal mode is 54 km/h; The drone will operate smoothly in headwinds up to 12 m/s and air temperatures from -10° to 40°C.
The O3 Industry Edition data link system will allow operators to control the Mavic 3M from up to 15 km away. The image will be transmitted to the DJI RC Pro Enterprise at a resolution of 1920×1080 pixels.
The automatic obstacle avoidance system is responsible for flight safety – built-in sensors with a wide viewing angle are directed in all directions.
Tons of uses
Numerous application scenarios for the new model include:
- Mapping of fruit plantations. The Mavic 3M can capture high-quality aerial photography not only in flat terrain, but also in sloped areas such as vineyards. Based on images taken using the DJI Terra software or the DJI SmartFarm platform, users will be able to create relief maps of farmland, which will mark all trees or shrubs. Subsequently, such maps will be useful for building routes for agricultural drones that will process plantations.
- Determination of the required amount of fertilizer. The Mavic 3M is capable of multi-spectral field surveys – in the DJI Terra software or on the DJI SmartFarm platform, maps with vegetation indices (NDVI and others) can be created based on such images. Such information will allow specialists to determine the potential yield of plots and calculate the required amount of fertilizer. This, in turn, significantly optimizes costs and reduces the level of environmental impact.
- High-precision monitoring of agricultural lands. The images that the Mavic 3M sends in real time via 4G network to the DJI SmartFarm platform can automatically detect existing problems such as flooded fields, piles of soil, weeds, etc. The drone can also “see” the development phases of planted crops. Such monitoring will significantly reduce the time and resources required to protect fields and control lands.
The information received by the drone can be used not only in proprietary DJI programs. The DJI Cloud API allows you to connect to third-party cloud platforms for data analysis. The received data can also be simply loaded into other software (the data format is unified for any software). The Mavic 3M also supports the Mobile SDK 5 (MSDK5), which allows users to create their own advanced monitoring applications.
We list the main advantages of the Mavic 3M professional drone:
- compact multispectral camera operating in 4 bands;
- advanced 20 MP RGB camera with 4/3 format CMOS matrix;
- high mobility (weight 951 g, dimensions 223 × 96.3 × 122.2 mm when folded);
- the possibility of inspecting up to 200 hectares in one flight (up to 43 minutes);
- integrated software: DJI SmartFarm and DJI Terra;
- work not only in flat areas, but also on slopes.
Mavic 3M is not an agricultural drone: it cannot scatter seeds and fertilizers (like XAG models). Nevertheless, the huge potential of the drone in mapping and monitoring farmland makes it a reliable and effective working tool for farmers.
