OVERVIEW
Space Guard is a long-range S-band radar system that detects and tracks space objects in Low Earth Orbit (LEO). Over the past half-century, numerous rockets and satellites have been launched into space, and as they become out of service, they turn into uncontrolled space debris that endangers and collides with active space platforms. By performing detection, tracking, identification, and cataloging of space objects, as well as supporting Space Traffic Management, Space Guard provides effective Space Situational Awareness (SSA) to ensure the ongoing safety of space operations.
Wide Coverage Tracking
The radar employs digital beamforming and wide beam coverage to monitor a large volume of space while simultaneously tracking multiple objects.
HIGHLIGHTS
- Space Situational Awareness
- Autonomous detection surveillance, tracking, and cataloging of all space objects
- Track satellites: potential collisions, maneuvers, breakups etc.
- Tracks – more than 1000 objects
- ±60° azimuth on each axis
- Support for Space Traffic Management
- Orbit propagation, predictions, analysis and assessment for all objects
- Space objects’ collision assessment
- Alerts operators of inevitable collision allowing ample time to maneuver the satellite onto a safe path
Values & Benefits
The radar incorporates Active Electronically Scanning Array (AESA) technology based on Gallium Nitride (GaN) RF modules combined with advanced algorithms and signal processing capabilities to effectively discriminate space debris and catalogue it for further investigation.
The system supports a seamless interface with a customer’s database and command and control system, as well as external global sources.
The radar is interoperable with other space sensors, including cameras and legacy sensors, and is based on ELTA’s field-proven Ballistic Missile defence (BMD) radars.
