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.


  • Pre-calculated motion vectors: Even before the operator acquires a target, Transas 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.
