Autonomous airborne intelligence

Know the ground before you break it.

A towable trailer, two drone classes, one AI brain. Scouts fly first — LiDAR and RGB to clear corridors and map terrain. Probes follow with ground-penetrating geophysics. Overlord assigns zones, phases sorties, and re-plans as data lands.

Geophysics today is slow, destructive, expensive, or coarse. The next survey of your land should arrive on a trailer, fly itself, and land in your inbox as a meter-scale heatmap by week's end.

The system

Endur Dock

Drive in. Drones up. Heatmap out.

A towable enclosed trailer carrying the whole survey system — drone dock bays with auto-charging LiPo cycling, a local Overlord compute node, LTE / WiFi backhaul, and shore-power or generator input. We tow it to your site, level the trailer, deploy in roughly fifteen minutes, and start flying Scouts.

Drone class — Scout (LR-01)

Endur Scout

Goes first. Clears the air. Maps the terrain.

Vertical-capsule airframe with eight coaxial rotors and a gimbaled LiDAR turret on a slip-ring assembly. Sweeps the zone, builds the terrain model, and hands a cleared corridor to the Probes flying behind it.

Drone class — Probe (PR-01)

Endur Probe

Follows the corridor. Sees through the surface.

Larger survey airframe carrying ground-penetrating radar, frequency-domain EM, magnetometer, hyperspectral and radiometric payload. Each sensor is multi-frequency and multi-power — frequency picks the resolution, power picks how deep the signal still returns useful contrast. Probes sweep both axes per pass and stack the shallow, mid, and deep returns into one volume.

Traditional-method values are public benchmarks. Endur values are pre-flight estimates from the current build and will firm up once integration testing completes.

Platform

One fleet, one brain, every layer of the survey stack.

Terrain mapping

LiDAR point clouds and DEMs the moment Scouts return from a sortie.

Subsurface inversion

Frequency sets resolution, power sets depth. Both axes swept across each flight, then fused into 3D mineralization volumes.

Anomaly detection

Magnetic, electromagnetic, and hyperspectral anomalies surfaced as you fly.

On-device autonomy

Every airframe flies itself — no remote pilot, no ground tether.

Phased sortie planning

Overlord splits the site into zones and runs Scouts first, then Probes. It works on a single pair and parallelizes automatically across whatever's in the hangar.

Degraded comms

The fleet keeps operating when the link to Overlord drops.

Current state

What we've actually built — and what we haven't yet.

    First on-property scan for a landowner partner. Free, in exchange for permission and feedback.

We'd rather show grant officers and first survey partners exactly where we are than claim flight time we haven't logged.

One trailer. One software stack. Three places it pays for itself.
