Deep Trekker introduces ROV GPS navigation

Deep Trekker is introducing a new navigation system called ROV GPS to its Revolution and Pivot models. 

One of the biggest challenges facing Remotely Operated Vehicle (ROV) operators is knowing where the robot is, and where it’s headed. Deep Trekker describes its new system as a ‘Game Changer in Underwater Navigation.’

How ROV GPS works

Traditional GPS – which triangulates using satellite fixes – is ineffective underwater. Deep Trekker’s ROV GPS system utilises enhanced surface positioning to keep the ROV in the right place.

Looking like a stubby periscope mounted on the top of the vehicle, the ROV GPS system is constantly recalibrating when on the surface. It calibrates in tandem with Deep Trekker’s dead reckoning module to improve tracking precision further.

To achieve the highest accuracy, ROV GPS supports Real-Time Kinematic (RTK) and Satellite-Based Augmentation System (SBAS) corrections.

RTK integration enables positioning accuracy as fine as down to 2.5 centimetres, significantly improving the precision of underwater surveys and inspections.

The system supports major satellite constellations including GPS, GLONASS, BeiDou, and Galileo.

With the ability to log GPS waypoints and record the complete history of ROV movements, operators can analyse data post-mission.

No USBL system required

One of the key benefits of Deep Trekker’s ROV GPS is its ability to deliver precise surface-based navigation without relying on a USBL (Ultra-Short Baseline) underwater acoustic system.

This feature is particularly valuable in challenging environments, such as noisy or magnetically disturbed waters where USBL systems may be impractical or cost-prohibitive.
