Laser Targets for
Dynamic Positioning...
because a clear view matters
L ASER TARGETS
• CyScan compatible
• Industry standard
• Easy to mount
• Cluster configurations for varied
angular visibility
• Dimensions specifically chosen
for optimal performance
The CyScan laser sensor operates with a variety of flat, cylindrical or prism targets. Laser
targets are retro-reflective and return the pulsed laser beam reflection back to the sensor.
The sensor accurately measures the range and bearing to the reference target(s) to allow
the calculation of relative position and heading. Retro-reflective laser targets are typically
installed on all offshore platforms. A range of high quality targets are available to suit all
operational requirements.
Applications
Laser Targets are suitable for applications which use
fixed structures such as:
• Platform and Offshore supply
• Accommodation barges
• Crew boats station-keeping
• Multi-purpose supply vessel
• Heavy lift activities
• Dive and ROV support
• Fish farms
Laser Targets are also suitable for applications with
mobile structures such as:
• Track and ship-follow
• Shuttle tanker loading
• Pipe and cable laying
• Rock dumping
• Replenishment at sea
Delivering the future in dynamic positioning
with consistently accurate products.
Flexible and Non-Flexible Prism Cluster Targets
Prisms reflect almost all the light received and provide the maximum signal strength allowing for longer operation in deteriorating
visibility. They are typically mounted in clusters to provide a greater angle of visibility and/or to increase the signal response in
locations prone to low visibility.
Typical Operating Range
with CyScan MK4
• 10m to 1250m (standard)
• Up to 2500m (with long
range licence)

Tape Targets
Reflective tape targets rely on having enough randomly scattered reflective material within the tape that some will retro-reflect.
These are lower cost solutions but the signal attenuation at the reflector limits the maximum operating range and will cause
a much earlier loss of signal in deteriorating visibility. They are short range, entry level reflectors and are recommended for
augmenting prism clusters at installations with complicated layouts and cluttered vessel approaches.
For maximum safety, Guidance always recommend glass prisms.

Guidance can manufacture customised tape
targets at the user’s requests. An example
includes a 1.5m target customised to wind-farm
projects.

E. Cylindrical 0.85m long
*To maximise the true performance of the
CyScan, Guidance will only provide the best
quality adhesive coated, sealed, retroreflective clusters and 3M diamond grade
tape which provides up to 50% greater retro
reflective efficiency.

This target is used for commissioning and testing
purposes only. It is not recommended as a DP
target. Instead use the 1.9m cylindrical, or better
still, a prism.
