Resources

GEOLUT-600 from Honeywell Global Tracking is a local user terminal (LUT) that processes 406 MHz distress beacon alerts over geostationary satellites, and provides rapid notification to SAR authorities worldwide. The GEOLUT-600 is part of an integrated and comprehensive search & rescue (SAR) solution from Honeywell Global Tracking.

Reliability

The GEOLUT-600 offers exceptional uptimes, accuracy and reliability, and has been at the heart of worldwide SAR operations for decades

Fast Detection

GEOLUT-600 systems detect emergency alerts within seconds in each coverage area, making it possible to start SAR efforts immediately

Advanced Signal Processing

Using noise-reducing signal processing, GEOLUT systems can minimize alert errors, leading to more efficient use of SAR resources

Flexible

Fully configurable, making it possible to precisely match the needs of customers

COSPAS-SARSAT Standards compliant

Meets and exceeds the official COSPAS-SARSAT requirements;

Capabilities

Supports ELT(DT) and RLS; Supports First and Second Generation Beacons

Seamless integration

Ease-of-integration into existing SAR systems saves time and money

Product Details

The GEOLUT-600 can be used in conjunction with data from low earth-orbit (LEO) satellites in a dual mode LEO-GEO system that provides unrivalled processing capabilities and reduces SAR response times.

The GEOLUT-600 makes it possible for SAR operators to quickly collect key information about beacons. This initial process can often identify false alarms prior to the retrieval of precise beacon location data from the LEOSAR system and ensures that SAR resources will only be used for actual emergencies.

A new motorized antenna system with an aluminium reflector and a controller which is able to utilize the AGC feedback from the RF subsystems and actively stay in beam, maximizing the signal reception from all GEOSAR satellites even when they are in an elliptical orbit. The Controller also can be programmed to switch from one satellite to another at the click of a button or using the remote web interface. Customised RF solutions available for optimal tracking of all GEOSAR satellites (GOES/Electro/MSG/Louch).
