LASEREF IV Inertial Reference Systems
                                        - 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
