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.
Advanced Signal Processing
Using sophisticated Doppler-based signal processing, LEOLUT systems can pinpoint locations of older alert beacons not equipped with GPS, enabling coordinated SAR operations.
Efficient
LEOLUT-600 provides fast ambiguity resolution of alert beacon signals, especially in geographies where fewer satellites may be seen, leading to more efficient use of SAR resources.
Flexible
LEOLUT-600 systems are fully configurable, making it possible to precisely match the needs of customers.
Standards Compliant
LEOLUT-600 terminals meet and exceed the official COSPAS-SARSAT requirements.
Seamless Integration
Ease-of-integration into existing SAR systems saves you time and money.
Rugged
The LEOLUT antenna’s reinforced mount is corrosion-resistant, providing years of maintenance-free use.
Works in up to 300 km/hour Winds
The low cross-section of the radome enables the antenna to operate in winds of up to 300 km/hour – a crucial requirement during hurricane or typhoon conditions that typically lead up to emergency situations.
Field-Proven
Our LEOLUT antenna technology has been proven in operational use on many satellite ground station installations around the world, minimizing the risk of interrupted SAR operations.
Product Details
The LEOLUT-600 automatically monitors alerts coming from LEO satellites orbiting the earth. Using triangulation and advanced Doppler processing, the LEOLUT-600 terminal can pinpoint the location of an alert signal in its coverage zone, even if the beacon is not equipped with the Global Positioning System (GPS).
LEOLUT-600 systems are fully configurable. They also exceed COSPAS-SARSAT data analysis requirements, providing fast ambiguity resolution in distress situations.
You can use the LEOLUT-600 in conjunction with data from geostationary (GEO) satellites in a dual mode LEO-GEO system.
- Provides unrivalled processing capabilities.
- Optimizes beacon location accuracy.
- Reduces SAR response times.
The LEOLUT terminal and antenna are part of an integrated and comprehensive search and rescue solution from Honeywell Global Tracking, a global leader in the development of search and rescue technology. We’ve been pioneers in the field for over 30 years. That’s a level of commitment and expertise you can trust.
