GRi VROV is a real-time subsea simulator for ROV/AUV engineering, pilot training and mission rehearsal. It combines vehicle, tether, manipulator, tooling and sonar models with bathymetry and environmental inputs, and can exchange data with real control hardware. Analysis, training and live visualization are distinct modes; a separate LARS simulator can be integrated for team rehearsal.

Use & integration
Recorded applications
Small-ROV operator training
Defence and subsea mission rehearsal
Competency assurance
Launch and recovery training
Subsea access testing and planning
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Commercial simulation offering with documented control-interface options. Node Zero records establish participation in a completed funding period, not completed field trials or validation of every simulator configuration.
Commercial availability
GRi offers configured simulation and interface development; agree the customer vehicle model, controller interface, scenario fidelity and training assessment before acceptance.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
GRi Simulations's ROV, underwater-sensing, inspection or mission-support capability could improve rapid collection and interpretation of public-source subsea observations.
GRi Simulations's vehicle, navigation or operator-support technology could contribute to repeatable uncrewed monitoring workflows when integrated into an approved mission system.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.

These records support this capability and its published Mission area and Defence need connections. A source count is not a count of independent confirmations.
