ADS-B receiver

for air traffic

Overview
ADS‑B (Automatic Dependent Surveillance—Broadcast) equipped aircraft broadcast GNSS‑derived position and flight data once per second. An ADS‑B ground station receives aircraft identification, position, altitude, speed and velocity vectors directly from the aircraft navigation systems. Unlike primary radar or multilateration, ADS‑B provides dependent surveillance based on onboard navigation data.

Key benefits

• Easy deployability and minimal ground infrastructure
• Long‑range surveillance achievable from a single ground station
• Typical update rate: one message per second (1 Hz)
• Cost‑effective coverage for surveillance and traffic monitoring
• Upgradeable to composite solutions combining ADS‑B and WAM for redundancy

Technical specifications

• ADS‑B broadcasts GNSS position and flight parameters (typically once per second)
• Received data: aircraft identification, altitude, ground speed, velocity vector and operational parameters
• Dependent surveillance: relies on aircraft navigation systems instead of ground interrogation
• Composite surveillance option: integration of ADS‑B and Wide Area Multilateration (WAM)
• Single‑station long‑range coverage possible depending on site and antenna configuration
• Update rate: ~1 message per second (1 Hz)
• Designed for straightforward deployment and phased expansion
• Upgradeable path to WAM (example: NEO upgradability)
• ERA NEO: distributed, modular architecture for scalability
