Which Positioning Reference Systems (PRS) are capable of utilizing multiple targets?

Laser and FMCW (Frequency Modulated Continuous Wave) Radar positioning reference systems are equipped to utilize multiple targets for dynamic positioning. This capability allows them to effectively triangulate their position by measuring distances to several points simultaneously, thereby enhancing accuracy and reliability.

Laser systems can target multiple reflective points, while FMCW radar can simultaneously detect multiple moving targets or stationary reflectors, thus providing real-time positioning data. This is crucial in operations such as offshore construction, where having multiple reference points increases the robustness of the positioning solution.

In contrast, GPS, while capable of providing positioning data, does not inherently utilize multiple ground-based reference targets for accuracy in the way that laser and radar systems do. Sonar systems primarily depend on underwater sound reflections and typically focus on single targets at a time for depth measurements. Gyroscopes provide orientation data rather than direct positioning and do not interface with external reference points for triangulation.
