Secondary surveillance radar (SSR) — also called cooperative surveillance radar — provides precise aircraft identification, altitude, and tracking by interrogating aircraft transponders. Collins Aerospace delivers proven Mode S and monopulse SSR (MSSR) systems, including the next-generation Condor Mk3, supporting civil and military airspace worldwide.
Cooperative surveillance for modern air traffic
Collins’ cooperative SSR solutions integrate seamlessly into terminal, en route, and surface operations, giving air traffic controllers accurate, real-time aircraft data. These systems enhance safety, efficiency, and situational awareness across complex airspace environments.
Introducing Condor Mk3 – Next-Generation MSSR
The Condor Mk3 builds on Collins’ successful SSR heritage to provide:
- High-duty cycle transmitter for superior detection
- Built-in ADS-B decoding with patented algorithms
- Reduced maintenance with fewer line replaceable units
- Reliable performance in dense or cluttered airspace
- Combines advanced cooperative radar technology with proven operational reliability.
Global deployments and proven performance
Collins Aerospace has installed more than 800 cooperative SSR systems worldwide for major Air Navigation Service Providers (ANSP) and defense customers, including:
FAA (U.S.)
- NATS (UK)
- Deutsche Flugsicherung (DFS, Germany)
- Royal Netherlands Air Force
These deployments highlight trusted performance, interoperability, and compliance with international air traffic standards.
Integrated with air traffic automation
Cooperative SSR solutions, including the Condor Mk3, connect directly to air traffic automation systems such as controller workstations, Standard Terminal Automation Replacement System (STARS), and AutoTrac. This enables real-time decision support, improves controller efficiency, and modernizes legacy infrastructure.
