How do I implement ADS-B aircraft tracking using a low cost RTL-SDR dongle?
ADS-B SDR Tracking Setup
ADS-B tracking is the most popular SDR project in the world: thousands of hobbyists run ADS-B receivers that collectively form a global flight tracking network (Flightradar24 and FlightAware are largely powered by volunteer feeders).

- Performance verification: confirm specifications against the application requirements before finalizing the design
- Environmental factors: temperature range, humidity, and vibration affect long-term reliability and parameter drift
- Cost vs. performance: evaluate whether the application demands premium components or standard commercial grades
- Interface compatibility: verify impedance, connector type, and mechanical form factor match the system architecture
- Margin allocation: include sufficient design margin to account for manufacturing tolerances and aging effects

Frequently Asked Questions
What range can I expect?
Typical ADS-B reception range: indoor antenna (on a windowsill): 50-150 km. Outdoor ground-plane antenna (on a roof or mast): 150-300 km. Outdoor collinear antenna with LNA: 250-450+ km. The range is limited by: line-of-sight (the Earth's curvature blocks the signal beyond approximately 400 km for an antenna at 10 m height; aircraft at 40,000 ft can be seen at approximately 420 km from a sea-level station), terrain obstructions, and local interference (other signals near 1090 MHz).
What is the recommended setup?
The most popular ADS-B feeder setup: Raspberry Pi (any model, $35-75) + RTL-SDR Blog V4 dongle ($30) + outdoor 1090 MHz antenna ($15-50). Total cost: approximately $80-150. Software: PiAware (FlightAware's Raspberry Pi image with built-in ADS-B decoding and feeding), or readsb + tar1090 (for a standalone, self-hosted solution). The Raspberry Pi runs continuously (2-5 W power consumption) and feeds data to FlightAware, FlightRadar24, and/or ADS-B Exchange. In return: FlightAware provides a free Enterprise account (normally $90/month) and FlightRadar24 provides a free Business subscription.
Is it legal?
Receiving ADS-B signals is legal in virtually all jurisdictions: the signals are broadcast unencrypted on a public frequency, specifically intended to be received by anyone (ground stations, other aircraft, and hobbyists). No license is required. No privacy concern: ADS-B data is intentionally public (it is the equivalent of a license plate for aircraft). Feeding: contributing your data to aggregation services (FlightAware, FR24) is encouraged and legal. Note: some countries restrict the publication of military aircraft positions; most aggregation services filter out military aircraft automatically.
