Overview

The Geostationary Earth Orbit Local User Terminal-600 (GEOLUT-600) processes 406 MHz distress beacon alerts over geostationary satellites, and provides rapid notification to search and rescue (SAR) authorities worldwide. It’s part of an integrated and comprehensive SAR solution from Honeywell Global Tracking. The GEOLUT Antenna is a fixed parabolic antenna that operates in up to 110 km/hour winds. The antenna allows GEOLUT terminals to receive distress alerts relayed through a single COSPAS-SARSAT GEOSAR satellite. This robust device offers high parabolic accuracy and has an RF feed assembly suitable for receiving and downconverting the GEOSAR downlink signal.
