Proven multilateration and ADS-B cooperative technologies deliver high-performance, high availability surveillance solutions for surface movement, terminal area and wide area en route control applications. The cost effectiveness, flexibility, accuracy and reliability of ERA’s technology are applicable to all surveillance requirements from the most complex airport surface to the most remote en route region.  

MSS by ERA is based on the proven time difference of arrival (TDOA) multilateration principle to provide an accurate and reliable real-time location and identification of all aircraft, vehicles and other objects equipped with a Mode A/C/S transponder. The system also decodes ADS-B signals according to all applicable standards (such as RTCA DO-260A and B) and can be configured as a stand-alone network of redundant ADS-B ground stations, capable of independent ASTERIX output.

Besides offering complete and accurate information, MSS by ERA features trouble-free operation, with high MTBF, no rotating parts, few replaceable spares and a comprehensive control and monitoring system.  

ERA’s unique ability to combine distributed timing architecture (based on GPS or reference transponders) with central timing architecture (ideally suited to complex airport layouts) ensures that each system can be optimized to the unique requirements and constraints of any solution, from wide area to surface.
