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
- 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
