Shipcontroller DPS
Shipcontroller DPS is an automatic control system that maintains the boat’s position and heading within very tight margins of error. Launched in 2021, it marked a milestone by being the first affordable, general-purpose DPS system that can be installed with a wide variety of boat propulsion configurations.
Shipcontroller DPS is especially useful in situations such as:
- Preparing for docking or anchoring, keeping the boat in position while you prepare the fenders or anchor.
- During docking or anchoring maneuvers, helping maintain the position while you carry out the maneuvers.
- While waiting for your turn to refuel.
- In bottom fishing, keeping the boat positioned over the fishing ground without needing to deploy a long anchor line.
Shipcontroller DPS is activated, deactivated, and controlled via a EZVector or DockerPro remote control. In fact, DPS is one of the operating modes of the remote.
The DPS system also offers a docking assistance feature: when activated, the remote retains full control of the propulsion systems. The assistance function allows you to easily adjust the boat’s position or heading using the remote controls, and when you release the controls, DPS automatically reactivates to maintain the current position. This provides valuable assistance and ensures safety during docking or approach maneuvers.
Shipcontroller DPS Features
Shipcontroller DPS is offered as an expansion option for the modular Shipcontroller system. A complete DPS system includes:
- A Shipcontroller remote control system, providing essential CANbus connectivity and control of the boat's propulsion.
- A Navigation Reference Unit (NRU), which includes a high-precision GNSS receiver and a satellite compass, used as a source of position and heading data.
- A Dynamic Positioning Unit (DPU). This unit calculates the position and heading error relative to the desired values and transmits the necessary commands to maintain the boat in the desired position.
The selected NRU, HemisphereGNSS® V200n, ensures excellent characteristics for this application:
- Position accuracy: 30 cm RMS with active SBAS corrections.
- Heading accuracy: 1.5º RMS, optionally 0.75º.
The NRU in a Shipcontroller DPS system is specially configured for this use and dedicated exclusively to the DPS system. (An NMEA2000 bridge kit is available to securely share NRU data with the boat's NMEA2000 network).
The DPU also cyclically monitors operating parameters, and in the event of a critical error, it deactivates the DPS system and triggers a visual and audible alarm to warn the captain.
Applications and Suitability
Shipcontroller DPS can be installed with a wide variety of propulsion configurations, as long as they are compatible with Shipcontroller.
The best results are achieved when the boat is equipped with proportional control bow and stern thrusters. Modern electric thrusters, brushless, with proportional control and long operating times, are ideal for Shipcontroller DPS, as well as hydraulic thrusters.
Regarding the main engines, single-engine configurations, as well as two or more engines, are supported. Electric propulsion is ideal for DPS systems, and excellent results are also achieved with azimuth/vector propulsion systems, such as IPS.
The ability of the DPS system to maintain position within specific margins of error depends primarily on the characteristics and capabilities of the boat's propulsion systems, as well as environmental conditions.
