Welcome to ADSBexchange.com, the world’s largest co-op of ADS-B/Mode S/MLAT feeders, and the world’s largest public source of unfiltered flight data. Access to worldwide flight tracking data opens up a whole new world of flight monitoring for hobbyists, researchers, and journalists alike.

This wouldn’t be possible without our amazing community of volunteers and feeders hosting airplane tracking equipment all over the globe. And we are always looking for new participants to expand our network. Be sure to check out the “how to feed” page to find out how you can help.

ADS-B Exchange differs from typical flight tracking sites in two primary ways.

First and foremost ADS-B Exchange does not participate in the filtering performed by most other flight tracking websites which do not share data on military or certain private aircraft. Because ADS-B Exchange does not use any FAA data there are no FAA BARR/LADD, military, or other “filters” preventing you from seeing the the data you collected. ADS-B Exchange simply does not accept payment or requests to remove aircraft from public tracking!

Second, we are a community. The data we have comes from volunteers, which is supplied back to the community through APIs. Donations are appreciated as they are used to help cover the costs of the infrastructure, archive, and all of the great things you see when using our site. And best of all feeders are eligible to get a personal use API key at no cost.

All commercial users are required to obtain a comercial use license from ADS-B Exchange, contact us here for terms. The money raised from commercial users helps cover the hefty infrastructure costs of processing Petabytes of data every month.

If you are interested in helping all you need is a Raspberry Pi, an SDR, and an Antenna which can all be had for $100 to $200 depending on how fancy you want to get, be sure to check out the “how to feed” page for more info.
