Contributor leaderboard

Your receivers contribute to one score. Hearing the same aircraft or Drone ID repeatedly—or through more than one of your receivers—counts once during the selected period.

Drone IDs heard counts Remote ID identifiers, not guaranteed unique physical drones. ADS-B counts aircraft ICAO addresses.

The public table shows the top 50. Sign in to see your own rank with up to 15 contributors either side. Equal scores share a rank: 1, 1, 3. There is no public member total or directory to page through.

Today starts at midnight UTC. Seven and thirty days cover the previous 168 and 720 hours.

Contributors appear after at least one accepted aircraft or Drone ID in the selected period. Invalid identities, known test broadcasts, simulations and replays do not score. Your aerial, location and nearby traffic all affect what you hear.

The first 100 contributors with genuine aircraft or drone reception and at least one hour of accepted receiver reporting receive a numbered gold Founding Member badge automatically. It is one award per member, not per receiver, and stays with them. Select a contributor to see their awards and what they mean.

Weekly awards use complete measured weeks and allow for late-arriving data before winners are finalised.

Only a public username and nearby city or town appear here. Never your email address, street address or antenna coordinates. If your sign-in name is not suitable for public display, we create a contributor alias automatically. You can change your public name in your account.

Multiple receiver locations may show “Multiple cities”. City labels use GeoNames under CC BY 4.0. Where no nearby town is available, no location is shown.

You can hide your receivers below without stopping their contribution.
