LEOLUT Antenna and Ground Station
- Reliability
The LEOLUT-600 offers exceptional uptimes, accuracy and reliability, and has been at the heart of worldwide SAR operations for decades
- Advanced Signal Processing
Using sophisticated Doppler-based signal processing, LEOLUT systems can pinpoint the location of alert beacons not equipped with GPS, enabling coordinated SAR operations
- Efficient
Provides fast position confirmation of alert beacon signals, especially in geographies where fewer satellites may be seen, 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 LEO-GEO processing. Capable of tracking MEO constellation. Supports ELT(DT) and RLS
- Seamless integration
Ease-of-integration into existing SAR systems saves time and money
Product Details
The LEOLUT 600 is fully configurable and exceeds COSPAS-SARSAT data analysis requirements, providing fast position confirmation in distress situations. The LEOLUT-600 can be used in conjunction with data from geostationary (GEO) satellites in a dual mode LEO-GEO system that provides unrivalled processing capabilities, optimizes beacon loca- tion accuracy and reduces SAR response times. |
