Boresight Systems

Harmolign is Metronor’s range of platform-specific turn-key solutions that enable any technician to quickly and accurately carry out boresight/harmonization of applicable weapons, sights, sensors, navigation units, hard points etc. The systems are fully MIL-STD and intended for use in operational environments. Entering service in 2006, Harmolign is currently in use on multiple platforms with over 20 armed forces around the globe – see References for more details.

With Harmolign, the boresight/harmonization process is simple: Power up the system computer, then follow the on-screen graphical guidance – the system includes active Built-In-Test provisions that also monitor operator actions to secure valid measurement results. This reduces training requirements and ensures reliable boresight/harmonization data.

Harmolign systems are modular and based around a range of standard components – such as the system computer, camera, tripods, LED pads and cabling – and platform-specific mechanical adapters. Harmolign software consists of a common executable controlled by a layer of platform-specific configuration files that can easily and affordably be modified and re-verified. The Harmolign concept is therefore optimized to cost-efficiently support platforms that may go through upgrades or equipment changes during their service life.

Harmolign systems come with an Accessories Kit that enables the operator to carry out a full end-to-end verification of system performance, thus avoiding scheduled re-calibrations and dramatically reducing Life Support Cost. For more details, see Calibration.


  • Provides orientation (Pitch Yaw Roll) as well as location (X Y Z) data
  • Handles any aircraft reference scheme – distributed or localized
  • No scheduled re-calibration – Built-In Test enables on-condition policy – Very high system availability and low Life Support Cost
  • Completely modular – excellent maintainability, repairability
  • Handles any number of LRUs, internally or externally on aircraft/weapons platform
  • Aircraft/weapons platform does not need to be jacked or levelled


Overall specifications will vary dependent on platform size and configuration, but typical data is:

  • Principle: Photogrammetry using computer-controlled LED targets and solid-state electro-optical sensors.
  • Accuracy: 0.1 mrad plus any contribution from aircraft LRU tray designs
  • Reliability: 2,400h MTBF (MIL-STD 217F and in-service data)
  • Environmental: MIL-STD 810F/G, ATEX Group XXXXXX, resistant to most fuels, oil and additives
  • Electromagnetic: CE marked, MIL-STD 461
  • Time to quote, new platform: 1-4 months after receipt of background data
  • Time to develop, new platform: 6-15 months after receipt of order (ARO)
  • Time to deliver, new platform: 7-18 months ARO
  • Design life: 30 years
