EDO RSS manufactures a variety of equipment for the ELINT (Electronic Intelligence), ESM (Electronic Support Measures), and SIGINT (Signal Intelligence) marketplace. These systems are designed for installation on aircrafts, ships or ground mobile/fixed sites. Typical applications include reconnaissance, surveillance, maritime patrol, situational awareness and air defense systems. In essence, these systems provide the operator with data that provides an electronic overview of the battlefield - the types of radar emitters present in the environment, their location and their classification. This enables the operator to reliably ascertain the answer to fundamental questions such as "Who is out here?" and "Where are they?".
