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.

For more information you can also visit LASEREF IV Inertial Reference Systems.
