Description
Effective aerial surveying needs to see the invisible. That's why Mavic 3 Multispectral has two forms of sight. It combines an RGB camera with a multispectral camera to scan and analyze crop growth with total clarity. Agricultural production management requires precision and data, and Mavic 3M delivers both.
Multispectral + RGB imaging system
Newly upgraded imaging system with one 20MP RGB camera and four 5MP multispectral cameras (green, red, red edge, and near infrared). Enables applications such as high-precision aerial surveying, crop growth monitoring, and natural resource surveys.
5 MP Multispectral Cameras
- Near-infrared (NIR) - 860 nm ± 26 nm
- Red edge (RE) - 730 nm ± 16 nm
- Red (R) - 650 nm ± 16 nm
- Green (G) - 560 nm ± 16 nm
RGB camera characteristics
- 4/3 CMOS
- 20MP image sensor
- 1/2000s Fastest mechanical shutter speed
- 0.7s Fastest per second Image Interval
Sunlight Sensor
The built-in sunlight sensor captures solar irradiance and records it in an image file, allowing for light compensation of image data during 2D reconstruction. This results in more accurate NDVI results, as well as improved accuracy and consistency of data acquired over time.
Accurate images that capture every pixelMavic 3M with RTK module for centimeter-level positioning. Flight control, the camera, and the RTK module sync in microseconds to accurately capture the location of each camera's imaging center. This enables Mavic 3M to do high-precision aerial surveying without using ground control points.
Ultra-long battery life, fast burstsA single flight can complete mapping operations over an area of 200 hectares[1]. A single battery can last 43 minutes[2] of cruise time. A 100W battery charging hub allows for the battery to charge in about 60 minutes.
Stable signal, smooth image transmission
The O3 transmission integrates two transmitting signals and four receiving signals to support 15km ultra-long transmission distances.
Omnidirectional obstacle sensing[3], terrain-follow aerial surveyingThe aircraft features multiple wide-FOV vision sensors that accurately detect obstacles in all directions for omnidirectional obstacle avoidance. The terrain-follow aerial surveying can be easily performed in steep-slope landscapes.
Orchard mapping
Mavic 3M allows terrain-follow aerial surveying of orchards, even on sloped landscapes. Together with DJI Terra or DJI SmartFarm Platform[4] to reconstruct high-resolution orchard maps, automatically identify the number of trees, distinguish trees from other obstacles or objects, and generate three-dimensional operation routes for agricultural drones, making operations safer and more efficient.
Guide variable rate applications
For rice fertilization, cotton growth regulation, and potato foliar fertilizer spraying, the Mavic 3M is used to obtain multi-spectral images of crops. DJI Terra or the DJI SmartFarm Platform[4] can then generate NDVI and other vegetation indices maps, capturing differences in crop potential and generating prescription maps that allow agricultural drones to execute variable-rate application. This ultimately allows users to reduce costs, increase yield, and protect the environment.
Intelligent field scouting
The Mavic 3M can carry out automatic field scouting. The field scout images can be uploaded to the DJI SmartFarm Platform[4] in real time through a 4G network. It can find abnormalities, such as emergence deficiencies, weed pressure, and crop lodging in a timely manner. It can also conduct intelligent analyses, such as cotton seedling identification and rice production testing, using AI identification for real-time sharing of crop growth information, guidance of agronomic activities, and easy management of 70 hectares of farmland by one person.
Environmental Monitoring and Natural Resources SurveyThe Mavic 3M can also be used in environment and natural resource surveys, such as water enrichment monitoring, forest distribution surveys, urban green area surveys, and more.
Notes1. Specific test conditions: In a sunny environment without wind, the orthographic flight aerial photography is obtained with a flight speed of 15 m/s, a flight altitude of 217 m, a ground sampling distance (GSD) of 5.73 cm for visible and 10 cm for multispectral, a fore-and-aft overlap rate of 70%, and a side overlap rate of 60%.
2. Data was measured using a DJI Mavic 3M flying at a constant speed of 36 kph at sea level in a windless environment until 0% power remained. It is for reference only. Please pay attention to Return to Home prompts on the DJI Pilot 2 app during flight.

3. DO NOT fly in severe weather conditions, such as in strong winds (wind speeds of 12 m/s or more), snow, rain, or lightning. DO NOT fly in areas that are 6,000 meters or higher above sea level. DO NOT fly the aircraft in environments where the temperature is below -10° C (14° F) or above 40° C (104° F). DO NOT take off from moving objects, such as cars and ships. DO NOT fly close to reflective surfaces, such as water or snow. Otherwise, the vision positioning system may not work properly. When the GNSS signal is weak, fly the aircraft in environments with good lighting and visibility. The vision system may not work properly in poor light conditions. Be aware of flight safety when flying near sources of electromagnetic interference. Common sources of electromagnetic interference include high-voltage power lines, high-voltage transmission stations, radar stations, cell phone base stations, broadcast towers, Wi-Fi hotspots, routers, and Bluetooth devices.
4. The DJI Smart Agricultural Platform will be supported in Q2 of 2023. This service is not available in some countries. Please consult your local distributor for details.
