The CyScan system consists of a laser sensor, a power supply unit, and a PC running the CyScan Console software.
The scanner rotates at 60rpm in an anti-clockwise direction. It emits a pulsed beam of infrared laser light and receives a reflected signal back from one or more retro-reflective targets.
CyScan accurately measures the difference between the time that each pulse is sent and the time that the reflected signal is received. It uses the 'time of flight' of the beam to calculate each target's range. The position of the sensor when the reflected signal is received is used to calculate each target's bearing.
The range and bearing information is used to calculate the relative position of the vessel to the target. Position data is continuously transmitted to the vessel control system via an industry standard electronic interface to allow station-keeping or a pre-set course or manoeuvre.
The scanner tilt mechanism automatically compensates for the pitch and roll of the vessel. Motion sensors and a two-axis tilt drive mechanism ensure that the scanning rotor remains at the correct level to see the target.

Prism Cluster Target | Flat Targets are 2 metres tall, and can typically be seen at up to 400 metres in ideal conditions.
Cylindrical Targets can be used up to approximately 250 metres. They are lightweight and can easily be deployed for either permanent or temporary operations.
Prism Cluster Targets with 8 x 6cm elements can be used for extended range operations. |
