Two crews, two trips
Surface LiDAR and subsurface GPR are scoped, scheduled and billed as separate jobs, often by separate firms.
Zero-entropy perception
See above and below ground in one pass.
Ectropix fuses LiDAR and ground-penetrating radar on a single rig. One crew, one trip, one co-registered 3D model of the surface and subsurface, at a fraction of the cost of two separate surveys.
- LiDAR surface
- GPR subsurface
The two-minute version
Precision data. Predictive models. Preventative maintenance.
Why we exist
Order out of disorder.
The name comes from ectropy, also called negentropy: the physical process of generating order out of disorder. We take high-noise sensor streams from above and below ground and resolve them into one clean spatial model.
- Purpose
- To reverse environmental chaos into clear, actionable physical intelligence.
- Mission
- Unifying surface point clouds and subsurface volumetric radar into a single, low-entropy perception engine for autonomous machines.
- Vision
- Every autonomous robot, from subterranean boring units to heavy construction rigs, navigating the physical world with absolute spatial clarity.
The problem
Knowing a site takes two surveys that never meet.
Stitched by hand
Point clouds and radargrams live in different tools and coordinate frames. Lining them up costs days and adds error.
Gaps become strikes
Incomplete subsurface data shows up later as utility strikes, redesigns and rework, once the excavator is already on site.
How it works
One rig, one pass, one model.
-
01 · Capture
Field rig
LiDAR, GPR and RTK positioning on one mount: cart, truck or robot.
-
02 · Fuse
Core
A shared clock and pose tie every radar trace to a point in the cloud, on board.
-
03 · Model
Vector
Cloud processing segments utilities, voids, strata and surface obstacles.
-
04 · Deliver
Outputs
CAD, GIS, voxel maps and ROS-ready data, plus an API to query it.
Surface and subsurface share one coordinate frame from the first point, so nothing is stitched by hand.
Products
Hardware at the edge. Intelligence in the cloud.

Economics
Where the cost comes out.
The savings don't come from one exotic sensor. They come from removing steps.
| Step | Conventional | Ectropix |
|---|---|---|
| Field crews | Separate LiDAR and GPR teams | One operator, one rig |
| Mobilizations | Two or more site visits | One pass |
| Registration | Manual, across separate tools | Automatic at capture |
| Interpretation | Expert reads every radargram | Auto-segmented, expert-verified |
| Deliverable | Separate drawings and reports | One 3D model plus an API |
