Easat is a leading supplier of Mode S Level 4 Monopulse Secondary Surveillance Radar (MSSR) systems for global Air Traffic Management applications.

Easat’s latest generation of Mode S Level 4 MSSR has been designed to ensure that it is fully compliant with ICAO requirements and Eurocontrol standards. Easat MSSRs are intended for cooperative air traffic control surveillance in accordance with elementary and enhanced Mode-S specifications.
