JPOS Station Keeping System
JPOS Station Keeping is a DP-0 system perfectly suited to workboats and fishing vessels of every size. Advanced yet easy-to-use technology that uses the vessel's GPS compass and is operated with a simple joystick — intuitive, with flexible integration into the ship's systems. Installation, start-up and calibration are done efficiently thanks to a unique autotuning function.
- Easy to use — joystick with large buttons, operable with gloves
- Robust and can be mounted out on the work deck
- Fast set-up thanks to autotuning during commissioning
The vessel holds position automatically.
GNSS feeds real-time position and heading to the DP controller, which continuously commands the thrusters to counter wind, waves and current. The operator doesn't steer to stay in place — the system does.
GNSS / Survey Compass
Real-time position and heading reference.
DP Controller
Continuously calculates corrections from position and sensor input.
Thrusters
Automatically compensate for wind, waves and current.
NAVY µLift + USBL
Deploys the transducer for reliable acoustic positioning.
ROV Feedback
Continuous position feedback keeps the vessel aligned to the ROV.
Dynamic Positioning modes
Position Keep
Holds the vessel on an exact position, automatically countering wind, waves and current so the crew can work instead of steering.
Heading Keep
Locks the bow on a chosen heading and holds it against environmental forces, while the operator remains free to move the vessel.
Follow ROV
Tracks a moving underwater target and keeps the vessel above it, so the ROV stays well inside its umbilical envelope during the whole dive.
Virtual anchor
Lets the vessel weather-vane naturally around a fixed point, using the least possible thruster power to stay on station.
Docking
Low-speed joystick control with fine translation and rotation for quay approaches and side-by-side operations.
Speed lock
Maintains a set speed over ground for towing, seabed mapping, survey lines and sampling runs.
Thruster mode
Direct, individual control of each thruster when the operator wants to manoeuvre entirely by hand.
Autotuning
The system learns the vessel's response during commissioning, so installation and calibration are done without manual tuning.
Delivered with software, integrated into the ship bridge system.
JPOS is delivered complete with its own software and is integrated into the ship bridge system, so position, heading, deviation and thruster status are available at the operator's station.
The display is available in two sizes, 5" and 7", so the panel can be fitted in the wheelhouse or out on the work deck.
