LASEREF Marine Product Family

Honeywell's navigation portfolio for aerospace and marine applications includes LASEREF and TALIN subsystems as well as subcomponents such as ring laser gyros, accelerometers, and navigation-grade inertial measurement units. The LASEREF family is the de facto industry standard providing the lowest cost-of-ownership with exceptionally long life.

Based on our highly reliable ring laser gyroscopes and quartz accelerometers with more than 900 million hours of flawless performance, the LASEREF Marine family represents a new standard in the maritime industry. It is a platform with high position accuracy, integrity, continuity and availability—without International.

The LASEREF Marine system is available in three performance versions:

LASEREF Marine Inertial Navigation System (INS) – The HG2170 LASEREF inertial navigation system is the world's most reliable marine INS with three to four times longer lifetime than competing systems and proven high-accuracy positioning in global positioning system (GPS)-denied environments. The system can incorporate multiple sensor inputs including a built-in stabilized gyrocompass to provide accurate positioning information even when an unobstructed GPS signal is not available. Based on the highly successful commercial aviation LASEREF product family, with over 300 million operating hours and 60,000 deliveries, this system provides long range navigation using Honeywell’s high-accuracy ring laser gyros and quartz accelerometers.
LASEREF Marine Attitude & Heading Reference Unit (AHRS) – The HG2171 AHRS is a self-contained reference system that provides high-accuracy heading, pitch, roll, heave, and rate-of-turn data
LASEREF Marine Stabilized Gyrocompass (SG) – The HG2172 stabilized gyrocompass provides accurate heading, pitch, and roll data with higher reliability and a lower total cost of ownership than a mechanical gyro
These systems have been designed to support a wide variety of maritime mission scenarios while dramatically reducing installation time, weight, size, power and operating costs.

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
How often should industrial gas turbines undergo performance testing?

We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
What temperature ranges do your military-grade ICs support?

Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Are PMA parts interchangeable with OEM components?

Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
