Multi User Long Base Line positioning system
Typical application for a Multi User Long Base Line positioning system

Several individual vessels and ROV units can now position themselves using the same seabed transponder array of our Multi User Long Base Line positioning system.

Customer benefits

  • Provides high position accuracy (compared to standard LBL)
  • A small number of transponders serve all vessels and ROV’s
  • Secures high position update rate (down to approx. 2 seconds), which is essential in DP operations
  • Avoids transponder frequency collisions when vessels are working in the same area (all vessels are "listening" only)
  • Uses Standard Long Base Line transponders (MULBL is a mode setting)

The Multi User Long Base Line positioning system will specifically prove its value in deeper waters, as it can give a higher position update rate than both the Standard Method and other Multi User methods.
