Avoid extended AOG situations by pro-actively upgrading to LASEREF IV!

Proactive retrofit is desired to avoid very long AOG situations as these units are export controlled and it can take up to 6 months to get a license. Avoid a failure!

The LASEREF IV replaces the aging LASEREF II and III, which became obsolete in 2019 and are no longer supported by Honeywell.

Our LASEREF IV inertial reference system is an all-digital ring laser gyro based inertial reference system providing ARINC 429 and aircraft standard communication bus digital outputs.

Simple replacement solution for Laseref II and Laseref III:

  • Suitable for:
    • Bombardier CL-600/601-3A / 3R
    • Bombardier Global Express
    • BAe Hawker 800, 800XP (BAe 125)
    • BAe Hawker 1000
    • Cessna Citation X
    • Dassault F900A/B
    • Dassault F900C/EX
    • Dassault F50, F2000
    • Gulfstream G-IV/sp
    • Gulfstream G-V
  • Adapter Tray available for aircraft equipped with Laseref II.

Upgraded features: 

  • Automatic re-align function for post flight alignment for quick turns
  • Auto-calibration of the sensors to maintain optimal performance over time
  • High latitude alignment up to 78.25 degree north latitude
  • High latitude magnetic heading map
  • Improved maintenance with modular design and assembly
  • Interfaces with Honeywell's HG2021 GNSSU ARINC 743A receiver to provide optimal GPS/inertial hybrid computations
  • Interchangeable with LASEREF III
