Automated flight in close proximity to structures


WHAT WE DO

PreNav IS Precision Navigation.  

PRENAV’s commercial drone system is capable of precise, automated navigation in close proximity to cell towers and other vertical structures in order to capture detailed imagery and build accurate 3D reconstructions. This level of control is not possible with GPS, and to date, has only been seen indoors in research labs with expensive motion capture systems that cost hundreds of thousands of dollars.

PRENAV has developed a patent-pending navigation system that consists of a guidance robot on the ground and an aerial robot working in coordination to fly close to structures. Before flight begins, the guidance robot scans the environment to build a map, then tracks and shares position updates with the drone, keeping it on course even when dealing with wind. The system is operated via an intuitive touchscreen interface and requires no manual piloting skills, making it accessible to climbers, technicians, and anyone who is working in the industry today.

SOLUTION


HOW IT WORKS

 

1. SCAN

Before launching the drone, a guidance robot on the ground scans the structure to build a map of the environment.

 

2. PLAN

A 3D flight path is automatically generated to get full coverage of the structure.

 

3. FLY

The drone is guided along the 3D flight path with cm-level precision, and takes photos at specific locations.

 

4. UPLOAD

Photos are synced to the PRENAV cloud processing engine.

5. PROCESS

Images are assembled into a detailed 3D reconstruction of the asset.

6. ANALYZE

Image classification and machine learning algorithms generate insights and reports for customers.

 

IMAGE PROCESSING AND ANALYSIS

360° PERSPECTIVE

Rotate and view images of the structure in 3D.

ACCURATE MEASUREMENTS

Measure height above ground, azimuth, tilt, and dimensions of structural components.

CONTROLLABLE ZOOM

Zoom in to see nuts, brackets, and labels.
