P4 Multispectral Replaced by Mavic 3 in November 2022

Shift Signals Era End

DJI's decision to phase out the P4 Multispectral in favor of the Mavic 3 series back in November 2022 marks a pivotal transition in precision agriculture drones. This move reflects evolving demands for lighter, more versatile platforms amid rapid advancements in aerial imaging. Farmers and researchers who relied on the P4's multispectral data for crop health analysis now face choices between legacy stock and newer models that promise enhanced portability without sacrificing analytical depth. The replacement disrupts workflows but opens doors to streamlined operations, as demonstrated in recent field trials across Midwest U.S. farms in early 2023, where Mavic 3 successors achieved 20% faster data capture.

Sensing Redefined

The P4 Multispectral stood out with its six-camera array, blending one RGB sensor and five monochrome multispectral lenses to capture data across blue, green, red, red edge, and near-infrared bands. This setup enabled real-time NDVI mapping, revealing plant stress invisible to standard cameras. Operators praised its TimeSync system for aligning positioning data across all sensors, delivering centimeter-level accuracy during flights. Even as Mavic 3 takes over, the P4's spectral sunlight sensor compensated for varying light conditions, ensuring consistent readings from dawn patrols to midday surveys, a feature that transformed daily farm monitoring into precise science.

Navigation Edges Forward

Engineering feats like the RTK module and binocular vision sensors gave the P4 Multispectral robust stability, hovering with ±0.1 m vertical accuracy via vision positioning. GPS and GLONASS integration handled diverse environments, while infrared and obstacle avoidance systems prevented collisions up to 98 ft away. These advances powered 27-minute flights at speeds reaching 36 mph in sport mode, covering up to 0.63 km² per battery drain in optimal setups. Post-2022, such capabilities underscore why DJI pivoted to Mavic 3, refining these for even tougher wind resistance and longer-range OcuSync transmission.

Fields Transformed Daily

Precision agriculture thrived under the P4 Multispectral, with NDVI and NDRE analysis spotting irrigation gaps in California vineyards during 2022 trials, boosting yields by 15%. Forestry teams deployed it for canopy density checks in Brazilian reserves, while conservationists monitored wetland salinity in Australian projects that same year. Agricultural research labs valued its global shutter for distortion-free imagery at high speeds, aiding soil composition studies. As Mavic 3 deploys in these roles, the P4's legacy persists in archived datasets fueling ongoing environmental strategies.

Specs Power Outcomes

Weighing 1.487 kg with a 350 mm diagonal frame (excluding propellers), the P4 Multispectral's 1/2.9" CMOS sensors—one RGB and five multispectral—enabled detailed NDVI/NDRE for crop scouting over vast fields. RTK and vision systems ensured precise mapping, while propeller guards and auto-landing enhanced safety during 27-minute missions. GPS/GLONASS navigation supported forestry scans, with batteries enduring 300-500 cycles for repeated conservation patrols. These specs directly fueled applications like resource monitoring, where infrared sensing dodged obstacles in dense vegetation.
