Overview

The Low Earth Orbit Local User Terminal-600 (LEOLUT-600) processes 406 MHz distress beacon alerts over low earth orbit satellites, and provides rapid notification to SAR authorities worldwide. It’s part of an integrated and comprehensive SAR solution from Honeywell Global Tracking. The LEOLUT Antenna is a phased-array antenna designed to operate in hurricane or typhoon conditions with up to 300 km/hour winds. It allows LEOLUT terminals to track low earth orbit satellites. The lightweight, roof-mounted device has digitally controlled motors, providing the entire range of motion required to track the COSPAS-SARSAT satellites.
