Guides
Once you've run a quickstart and confirmed the stream opens, these guides cover everything else you'll need to build a real client. For the underlying gRPC service / 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.
