RADius 800X

Relative positioning reference system

The RADius 800X transponder is a part of the short-distance relative positioning system RADius, developed for use in applications where the need for a robust and highly accurate relative positioning system is crucial. The system comprises an interrogator, installed on a vessel, operating in the 5.5 GHz band and transponders which are deployed on the target. The RADius 800X has an operating range of up to 1000 metres, and is suitable for fixed installations on typical a platform or an FPSO.

Transponder main parts

The main parts of the RADius 800X transponder equipment are:

  • The transponder panel and the transponder connection box with terminals for the DC voltage cable and a DIP switch for setting the Transponder Identification code (TID).
  • The transponder mounting bracket for horizontal or vertical rail mounting.
  • The Power and Barrier Cabinet, which is mounted in a safe area. The Power and Barrier Cabinet can supply up to four transponders.
