What we build

Autonomous positioning

Station-keeping and goto behaviours designed for repeatable field operation.

Embedded sensing

Platforms supporting wind, wave, current, and seabed inference where appropriate.

Data-first outputs

GPS-referenced outputs designed for mapping, planning, and decision-making.

Data capture & processing: Hold2X platforms support GPS-referenced imagery, photogrammetry workflows, and sonar-based bathymetry, integrated where appropriate.

Team

Hold2X is built by a team of five specialist engineers spanning marine systems, robotics, control software, geospatial data, and field deployment.

We focus on practical, test-driven development: build, deploy, measure, iterate.

How we work

Field-first prototypes and real deployments
Operator-clear control and communications
Outputs structured for spatial analysis pipelines

Data & visualisation

Hold2X systems are designed to feed directly into map-native review and sharing. see1m is our lightweight visualisation layer for selected outputs.

Use cases

Coastal monitoring and rapid near-shore surveys
Environmental response and repeatable positioning
Operations where anchors are impractical
