Autonomous and modular inspection platform

Structured approach from mission planning to actionable intelligence. Fully automated, individually customized.

How it works

End-To-End Process Overview

subdron enables precise undersea surveillance missions at zero visibility, based on our proprietary Relative Object Navigation (RON) technology.

1

PLAN

Every mission starts with careful planning. Together with the client, we define the inspection target, scope, and timeline. The mission parameters are configured in the ground control station, including route planning, sensor selection, and environmental conditions.
2

DEPLOY

A 1 or 2 person crew launches the autonomous vehicle on site. No pre-map or specialized operators are needed. The system is operational within minutes.
3

NAVIGATE & COLLECT

RON guides the vehicle autonomously along the structure, whether port wall, hull, or cable. It follows the target efficiently and precisely, collecting high-resolution 3D data via acoustic, optical or other sensors starting from 0 visibility.
4

PROCESS

The subdron cloud reconstructs cm-level 3D models, detects and classifies anomalies using ML algorithms, and compares data over time for predictive maintenance insights.
5

REPORT

Our web platform delivers interactive 3D visualizations with labeled findings. Reports are exportable, shareable, and require no expert interpretation.
Client Step

INTEGRATE & DECIDE

Clients can feed inspection results directly into their own asset management or maintenance planning systems. The standardized data format enables seamless integration, improving the speed and quality of decision-making across the organization.
RON - Relative Object Navigation

The only autonomous navigation system designed for confined underwater environments.

Proprietary navigation algorithms

Relative Object Navigation (RON) is subdron's proprietary core technology and algorithm. Unlike GPS-based or tethered systems, RON positions the vehicle relative to the inspected structure itself. This means the vehicle does not just locate the target. It follows the structure with maximum efficiency, maintaining optimal distance and angle to collect complete, high-quality data in a single pass. The result: faster coverage, fewer redundant runs, and higher data consistency than any manually operated or waypoint-based system.

Flexible payload

Multiple sensor setups, individual surveillance applications

• Acoustic: High-resolution 3D point clouds for structural inspection. Works in any visibility. Primary payload for port wall and hull inspection.

• 3D Volumetric Sonar: Captures volumetric data for faster, more robust 3D reconstructions compared to traditional MBES. Collects the equivalent of multiple sonar beams simultaneously.

• Optical Cameras: HD and 4K imagery for visual documentation, biofouling classification, and photo-mosaic generation. Requires moderate visibility conditions.

• Electromagnetic Sensors: 360° field-of-view for close-range detection and obstacle avoidance. Complements acoustic and optical data.

• Data Fusion: The subdron cloud can merge acoustic 3D models with optical imagery into textured, fully annotated 3D reconstructions, offering both structural accuracy and visual detail in a single output.

Because RON separates navigation from scanning, the sensor payload can be configured for each mission type.

RON is not just a feature. It is the reason subdron can navigate where others cannot, scan structures more efficiently, and deliver richer data from every mission. Combined with a flexible payload architecture, it turns a single autonomous platform into a multi-purpose inspection tool
