Feeds: Smart Ports and MLAT

1. Feed basics

In Feeds, define raw data sources (Beast, BaseStation).

For each feed, configure:

  1. Address and Port
  2. Format
  3. ConnectionType
  4. Enabled
  5. Visible in Radar Dropdown
  6. optional Receiver Location

After save:

  1. verify connection status,
  2. verify message counters increase,
  3. verify AircraftList.json is non-empty.

2. Smart profile ports

Known smart profiles:

  1. 30003 -> [ADS-B] BaseStation/Text
  2. 30005 -> [ADS-B] Beast/Binary
  3. 30105 -> [MLAT] Beast/Binary
  4. 30106 -> [MLAT] BaseStation/Text

When one of these ports is entered, feed editor pre-applies matching format/MLAT defaults.

3. MLAT options

Feed-level MLAT controls:

  1. MLAT Feed forces all positions from feed to be treated as MLAT-derived.
  2. Use MLAT Feed only for dedicated MLAT streams without reliable MLAT marker tagging.
  3. For mixed ADS-B + MLAT streams, keep MLAT Feed disabled and rely on per-message MLAT detection.
  4. Assume DF18 CF1 = ICAO is experimental and should be enabled only for known-compatible sources.

4. Quick verification

  1. open aircraft detail panel,
  2. check Position Source (MLAT position or ADS-B position),
  3. compare behavior before and after MLAT option changes.

5. UI visibility note

Visible in Radar Dropdown controls whether a feed appears in frontend All feeds / feed selector.
