RADius is developed for applications in need for 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).
The implementation is fully solid state and based on measurement of reflected radar signals from a number of passive transponders in the nearby area. Each reflected signal is mixed with a unique ID to separate different targets from each other. Advanced
signal processing allows simultaneous and continuous measurements to any practical number of transponders. RADius is designed for multiple users leveraging the same transponders simultaneously.
Multiple sensor heads
RADius can be deployed as an omni directional system utilising four sensor heads, which can be placed on suitable locations on the vessel dependent on the construction and operation. This provides full 360° signal acquisition as well as avoidance
of blind angles as there will be a sensor head at a receiving angle to transponders at all times, regardless of the vessels relative position to the RADius transponder.
Signal processing will effectively remove possible interference with other transmitting devices in the same frequency band. Accurate Doppler measurements allow for rapid and reliable determination of relative velocities between the manoeuvring vessel
Application software makes configuration and monitoring of the RADius operation easy and effective, and interfaces to remote systems like Dynamic Position may either be serial lines or Ethernet based.
RADius is designed to fill the need specified by IMO for DP Class 2 vessels.
RADius is capable of detecting and measuring accurate range and bearing to any transponder within the range of up to 550 metres. (Dependant on the targets transponder) The direction from the interrogator to each transponder is accurately determined
by the use of interferometric methods. Due to use of open standards, deployment of the operator interface is very flexible.
Wide opening angles
RADius has a vertical and horizontal opening angle of 90°. This secure stabile operations in close by operations where the difference in mounted transponder and interrogator can be considerable. Due to this there is not necessary to tilt the sensor
head in any direction to obtain signal.
A variety of transponders
Retro-reflective transponders are mounted on the target that are to be approached. A variety of transponders are available suitable for any operation that demands an robust and reliable relative positioning solution.
