Premium long range, high precision radar sensor

The RadaScan system is an advanced local position reference sensor for long range use in marine Dynamic Positioning (DP) applications. The sensor is a rotating antenna mounted on the DP equipped vessel. It emits a microwave beam and accurately measures the range and bearing of one or more intelligent microwave targets called responders, allowing for the calculation of vessel position and heading.

With an optional operating temperature of -40ºC, RadaScan is also available as an Extreme Low Temperature (XT) variant for Ice and Arctic operations.

"We have one on each of our vessels. RadaScan with the new responders is excellent and provide 360 degree coverage if properly sighted, from a single responder. Not having to purchase 4 individual interrogators to provide 360 degree coverage is of great benefit. I recommend Guidance Marine and their products without reservation"

    The user interface is common across all four sensors, to aid productivity and reduce cost of ownership.

    Microwave sensors (RadaScan and Mini RadaScan) operate with a variety of intelligent microwave targets called responders. Available in a variety of power options to suit the operation, responders can be mounted on a fixed structure, such as an offshore oil-platform for station-keeping, or on another moving vessel for track-and-follow operations.

    Mounting Options

    • Guidance Marine provide a universal swivel bracket which is suitable for all responder power and installation options. 

    Best Practice

    Guidance Marine recommends fixed installation for all responders regardless of whether it is a short or long term operation.

    The Primary Cell Pack (PCP) has a nominal 24/7 use expected life-time of 12 months under average temperature conditions, therefore the batteries will require replacing. No maintenance is required on the rechargeable responder. For more information click here.
