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.
