Four payloads, one airframe interface
RGB survey camera
61 MP full frame with mechanical shutter. The standard payload for photogrammetry and progress tracking.
Multispectral sensor
Five bands with an irradiance reference. Used for NDVI and crop stress maps.
Thermal camera
640×512, radiometric. For line inspection, fire detection and night search.
LiDAR
Dual-return scanner producing below-canopy terrain models and corridor cross-sections.
Software3D Model
The data pipeline
Flight planning
Autonomous line plans from a field or corridor boundary, with obstacle and altitude constraints written into the plan.
Processing
Orthophoto, elevation model and point cloud production, with an accuracy report attached automatically.
Delivery and archive
Outputs are archived with their coordinate system so they can be compared against earlier flights.
