Products > Wärtsilä Navi-Sailor ECDIS

ECDIS is a computer-based navigation information system compliant with the latest International Maritime Organization (IMO) regulations and is used as an alternative to paper nautical charts.

An ECDIS system displays the information from electronic navigational charts (ENC) and integrates position information from the Global Navigation Satellite System (GNSS), gyrocompass, speed log, other navigational sensors, radar and automatic identification systems (AIS).

Wärtsilä delivers a full range of type-approved ECDIS solutions that can be stand-alone or part of the Integrated Navigation Systems or Multifunctional Display i.e. Radar, Conning, Bridge Alarm Management, Track Control in one workstation.

Wärtsilä Navi-Radar 4000

Navi-Radar 4000 uniquely combines radar information, navigational charts, ENC safety parameters, targets, user-maps, routes and tools for decision support, which all ensure safer navigation.

With Navi-Radar 4000, chart layers can be individually configured, avoiding a cluttered radar display. The integration of ECDIS and Radar reaches a new level. Combining best of class in hardware (JRC) and software (Transas), the new Navi-Radar is a unique product from two renowned manufacturers.

Built on the Fleet Operation Solutions software platform it creates the perfect integration of (connected) ECDIS/ Radar but also allows remote trouble shooting from shore.

  • Pre-calculated motion vectors: Even before the operator acquires a target, Wärtsilä Navi-Radar 4000 already selects potential targets and provides you with instant vector and object data.
  • Target association: Built-in filters can associate any AIS and ARPA target to provide reliable, real-time data, selected by the operator.
  • Filtering lost targets: In heavily trafficked areas, focus is key to avoiding dangerous situations. Operator-defined target filters warn you only when necessary.
  • Trial Manoeuvres and Curved Heading Line: Real-time calculations and presentation strengthen any decision made by the officer.
  • Chart Radar: Efficient multi-loading and display of electronic charts where ENC/SENC or TX-97 charts can be presented as an underlay simultaneously with individually created MAPs.
