How the Layer400
receiver network works.
Local receivers listen for aircraft ADS-B and supported drone Remote ID broadcasts. Layer400 brings accepted reports together on a shared map, showing the traffic the network receives.
The contribution path
From radio to map.
Each stage has a job. Keeping them distinct makes the result easier to understand.
- Receive
A local radio hears a supported aircraft or drone transmission.
- Decode
The receiver turns the broadcast into a structured observation.
- Deliver
The receiver sends it to Layer400 and checks for acceptance.
- Display
Eligible reports contribute to tracks and coverage information.

What a useful map needs.
A real observation
A connection badge is not a received aircraft. Radio health, decoded data and accepted uploads are checked separately.
Read the receiver states →A useful location
An antenna installation point and an aircraft position are different things. Public coverage does not reveal the exact receiver pin.
Understand receiver privacy →A current report
Traffic moves. A report delivered after an outage is not automatically current live traffic.
Understand queued reports →Understand the received picture
Read data sources and measurement limits for the path from radio to map. Learn how to interpret tracks and playback and what an aircraft–drone proximity alert actually measures.
