Mode-S Monopulse Secondary Surveillance Radar M10S

M10S is a new generation Mode-S MSSR designed and manufactured by NRPL under ISO 9001:2008 certified quality system in full compliance with ICAO and Eurocontrol standards. It is intended for air traffic control cooperative surveillance in accordance with elementary and enhanced Mode-S specifications. It was designed using the latest, best-known technological improvements.

M10S can be used either stand-alone or can be easily integrated with PSR, ADS-B and MLAT systems. In this case, a common CMS will display status and performance parameters of all systems simultaneously and PPI screen will display combined targets processed by advanced built-in tracking system.

M10S is highly flexible, high performance turnkey solution with open architecture easily adaptable to customer requirements and needs of different sites, such as communication and maintenance facilities.
