Guides
These pages cover how the stream behaves — the data it delivers, how filtering works, and how to interpret timestamps. For the wire-level service and message definitions, see the API Reference.
General Guidance
How the update model, batching, compression, and reconnection behaviour affect your streaming client.
Filtering
Narrow the stream to specific aircraft, regions, or attributes with structured filter expressions.
Timestamps and Position Time
How the server `now` clock and per-aircraft `seen_pos` offsets combine to give precise position times.
