Guidance On RADius Relative Positioning System
The International Marine Contractors Association (IMCA) has just published 'Guidance on RADius Relative Positioning System' (IMCA M 224) describing the RADius microwave radar system. This document is produced by IMCA as an aid to members and others using position reference systems and forms part of a series of documents on the available systems.
In common with some previous documents on position reference systems, it has been prepared in the major part by the manufacturer of the system, in this case Kongsberg Seatex.
RADius, which utilises radar principles, has been developed for applications in need of a robust and reliable relative positioning system. Many applications can benefit from RADius in operations, as there are different types of retro reflective transponders and different types of installation of the sensor heads (interrogators). Furthermore, the RADius system is a solid state system – there are no motors, stabilised platforms or other moving parts – keeping the maintenance cost low.
