Kongsberg Seatex launched SpotTrack, a multi-target laser based relative position reference system. SpotTrack delivers accurate range and bearing measurements and is primarily intended for Dynamic Positioning (DP) operations.

Kongsberg Describes SpotTrack as a robust, lightweight, motion stabilized rotating laser sensor offering precision range and bearing readings to one or multiple retro-reflective targets. As a multi-target sensor, SpotTrack uses an advanced detection system and tracking algorithms for true target recognition – minimizing lock-on to false reflections. Motion stabilization provides improved target lock on a moving platform. SpotTrack can utilize already established, optical targets.

“Laser based reference systems represent an established technology, but SpotTrack introduces a new level of reliability and ease of operation for this type of product. The sensor itself is a completely sealed unit, with all moving parts housed inside, so the system is less prone to mechanical wear from exposure to the elements. By this approach we have created a more durable product well adapted to the requirements of critical operations, and with the benefit of less costly maintenance,” explains Vidar Bjørkedal, VP Sales & Customer Support, Kongsberg Seatex AS.

The SpotTrack is based on a proven DP reference system technology and is typically used in conjunction with satellite positioning, microwave based systems and subsea positioning. It can act as one of the three position reference systems required for the DP3 Class.

Though SpotTrack will primarily be used as a DP reference system, it can support other operations including automatic docking systems and vessel traffic monitoring. By utilizing roll and pitch stabilization from a motion reference unit, (KONGSBERG MRU) SpotTrack can track targets even at high elevation angles. This makes it suitable for close-by operations, such as 3D positioning for maritime construction.
