MK 39 Ring Laser Gyro

Inertial Navigation System

Benefits of Use

 

  • Low acquisition and through-life cycle cost
  • High reliability, low maintenance
  • No practical limitations on rate if attitude changes - can be used on virtually any hull type
  • Hands off operation, does not require operator intervention
  • Provides data at stated accuracies through severe shock events
  • Easy to maintain with access to all internal assemblies and LRUs
  • Can be monitored via existing combat system data bus
  • DC operation eliminates additional converters and UPS
  • Automatic fault isolation and system protection for critical failure modes eases troubleshooting and protects unit
  • Not affected by rapid changes in external magnetic fields, assuring high accuracy regardless of location
  • Replacement of MK39 can be done at sea with no further alignment required
