LASEREF IV Inertial Reference Systems

Overview
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.
  • Uses the industry standard GG1320 digital gyro
  • 35 percent weight and power reductions versus the LASEREF III
  • Lowest cost of ownership with higher reliability and improved maintenance
  • Save up to $50K per the HSB when you trade in your old LASEREF II or IIIs
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
  • Adapter Tray available for aircraft equipped with Laseref II
  • Simple replacement solution for Laseref II and Laseref III
