Kongsberg Seatex's SpotTrack™ is an advanced multi-target laser based relative position reference system. SpotTrack delivers accurate range and bearing measurements and is primarily intended for Dynamic Positioning (DP) operations.

SpotTrack™ is a highly robust, yet lightweight, motion stabilised rotating laser sensor offering precision range and bearing readings to one or multiple retro-reflective targets. As a multi-target sensor, it uses an advanced detection system and tracking algorithms for true target recognition – minimising lock-on to false reflections. Motion stabilisation provides improved target lock on a moving platform. SpotTrack can utilise 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.

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 utilising roll and pitch stabilisation 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.
