3.3 Location of the system parts
The following sections describe various procedures regarding mounting of the different
system parts:
3.3.1 The Interrogator Unit
For location of the Interrogator Unit, consider the following:
•
The sector which the Interrogator is supposed to cover. The Interrogator has an operating
sector of 90 degrees in both vertical and horizontal direction.
•
The longest Interrogator axis must be horizontally oriented.
•
The Interrogator should be located high above sea level.
•
The Interrogator should not be mounted close to the ship side, or other large metal
surfaces. This is to avoid multi path effects.
•
The Interrogator needs free line of sight to the Transponders.
•
The Interrogator should be mounted to a stiff mast, rail or wall to limit the risk of
mechanical resonances caused by vibration. Excessive (> 1 g rms) vibrations could affect
the quality of the measurements.
•
During dual Interrogator installations, the two Interrogators should ideally be mounted
with a 90 degree difference as shown in Figure 8. This will make it possible to cover 180
degrees.
Note! The longest Interrogator axis must be horizontally oriented, or else the RADius
system will not be able to track any transponders
.
A typical operational scenario for a single Interrogator solution is shown in Figure 3. The
system will typically operate against several Transponders simultaneously and the
Interrogator should be installed in the direction where the vessel will see one or more
Transponders in the operational environment. For a supply vessel a good location for
installation can be outside railing on top of bridge roof, pointing aft. To avoid multi path
effects during operation, it is important not to locate the transponders close to the ship/rig
side.
