The Equipment
What We Fly for This Work
Plant and utility work is flown on a Freefly Astro Max, designed and assembled in the USA, NDAA compliant and DIU Blue approved. More refinery, port, utility and public agency contracts now require Blue UAS hardware, and most commercial drones do not qualify, so this is the aircraft that gets through the gate. Its inspection payload is a Gremsy VIO F1: a 640 by 512 thermal sensor, a 4K zoom camera and a laser rangefinder, which is the combination you want for reading a hot connection from a safe standoff distance.
Where a site does not require Blue UAS hardware, a DJI Matrice 400 with the Zenmuse H30T thermal and zoom payload is also available.
Specifications are the manufacturer's published figures under the manufacturer's test conditions, from enterprise.dji.com, store.freeflysystems.com and gremsy.com, checked September 2026. Flight times carry their conditions on purpose: the Astro Max's 43 minutes is the bare aircraft, and a heavy sensor cuts it to 20. The Astro Max LiDAR payload is not listed because it is not settled; its figures go up when it is. Accuracy on a real job depends on canopy, ground control, weather and flight plan, and what we deliver is mapping data, not a survey.
