3 Overview
DP systems using relative position measurement equipment have been used in a wide range of industrial
applications where operation typically requires vessels to perform either:

‘station keeping’; e.g. maintain their position against fixed or moving installations for loading and/or unloading;

‘track and follow’; e.g. maintain the same heading and speed relative to another vessel.
These operations often require sub-metre accurate local reference measurements to be supplied to the DP
system. The Mini RadaScan sensor is a microwave based reference system that has been developed to offer an
accuracy that is comparable to a laser system combined with the capability to work in all weather conditions
where the presence of heavy fog, heavy rain, snow, dust or steam could affect the performance of laser systems.
A typical vessel will utilise a number of sensors simultaneously. Therefore each sensor needs to be capable of
operating without interfering with or suffering interference from other sensors.

The Mini RadaScan system builds on the success of RadaScan and is one of the latest developments in local
reference sensor technology. The Mini RadaScan is smaller and lighter than the RadaScan, thus making installation
easier and quicker, whilst providing crucial all-weather operation without compromising on accuracy.
Mini RadaScan has the same friendly and familiar user interface as RadaScan.
In the rest of the document, the term sensor will be used to refer to the Mini RadaScan unit unless stated
otherwise.
