Orolia launches Horizon search-and-rescue system

Orolia has introduced the McMurdo Horizon system, an S- and L- band compatible phased array system featuring antennas developed by Ball Aerospace with horizon-to-horizon coverage to capture search-and-rescue signals relayed from orbiting satellites immediately after line-of-sight is established.

The McMurdo Horizon system is now available to enhance regional search and rescue services worldwide with technology to complement existing and emerging ground-based systems at Medium-altitude Earth Orbit Search and Rescue (MEOSAR)ground stations.

Orolia’s McMurdo Horizon Medium Earth Orbit Local User Terminal (MEOLUT) can deliver enhanced search and rescue coverage and second-generation signal processing capabilities, in a compact form factor with no moving parts. The key technology innovation, based on a modified off-the-shelf phased array antenna developed by Ball Aerospace, is a custom-designed Orolia solution.

By pointing to satellites near the horizon, the McMurdo Horizon MEOLUT can detect and locate emergency beacons much farther away. This enhanced detection ability, combined with the McMurdo Selective Schedule Algorithm, enables the system to monitor more diverse regions, including the translation of oblong and irregular data points that are invisible to traditional systems.
