S-Mode Monopulse Secondary Surveillance Radar
ATM - Air Traffic
The RSMA-S is the latest generation S-MODE Monopulse secondary Surveillance radar developed by INVAP S.E.
It operates in today's modern air traffic scenarios. It is the new version of the RSMA, which since 2007 has been used without radome in the different environments of Argentina: from the cold "end of the world" in Ushuaia, to the humid subtropical climate of Misiones, from the heights of the Puna to the terminal area of Buenos Aires, and in seismic zones of the Cordillera de Los Andes. Our radar complies with ICAO recommendations and achieves the performance required by Eurocontrol for mode S stations.
With state of the art technology, it has interrogation capabilities in modes 1, 2, 3 / A, C, S (ELS and EHS).
It exhibits excellent performance in all modes of operation even in severe FRUIT and GARBLE conditions.
The RSMA-S also has ADS-B functionality to acquire, decode and process Extended Squitter messages emitted by aircraft.
The system is designed to operate even under the most adverse environmental conditions.
Its redundant design allows it to operate continuously, 24 hours a day, 365 days a year with high availability. It is designed to require minimal preventive maintenance, as well as to minimize operating costs throughout its life cycle.
