Hello everyone. I’m posting today to update the community on how we provide MLAT results to our data feeder users and clarify how you can use this data. For our long-time participants, you may already be familiar with most of this. We want to make sure everyone knows about this free service we provide and how we make that available to you. As you may know, providing MLAT calculation results back to PiAware/FlightFeeder users enables you to track many more aircraft in range of your receiver than you would otherwise be able to do with only ADS-B data.
FlightAware is pleased to make multilateration (“MLAT”) aircraft position data (“MLAT results”) available to PiAware and FlightFeeder network participants at no cost. FlightAware invests significantly in the hardware, software and network resources to provide this service as a benefit to users that feed data to FlightAware. In exchange for your participation, FlightAware freely licenses the use of the MLAT results data to you for your personal and non-commercial use as long as you are a data feeder to FlightAware. You may use the MLAT results in several ways:
Via the Skyview web site running on your PiAware or FlightFeeder device in the web browser of your choice.
Via the JSON file output used by the Skyview web site. (For use by advanced users; this is not formally supported by FlightAware.)
Via direct network connection to TCP port 30105 or 30106 within your local area network. (For use by advanced users; this is not formally supported by FlightAware.)
FlightAware does not allow redistribution of MLAT results data to third parties via any means for commercial use or consumption by the general public with the exception that you may share the Skyview user interface with other users if you choose. Sharing of the MLAT results data for commercial use or public consumption in formats such as JSON, Beast, Basestation or any other format is not permitted. Furthermore, any aggregation of FlightAware MLAT results with other data sources is not allowed except for your personal, non-commercial purposes.
Additionally, to maintain the quality of our data feeds and MLAT results, feeding of any data other than Mode A/C/S or ADS-B to the FlightAware network is not permitted. For example, you may not feed MLAT results back to FlightAware as if it were native ADS-B data. Other data sources such as ACARS or any data from third party sources may not be fed to FlightAware’s ADS-B network.
This policy is to ensure the quality of our network and compatibility with our data processing infrastructure. Additionally, this policy enables us to continue to provide MLAT results as a free benefit to our network of over 13,000 sites and growing.
Thank you for your participation in the FlightAware ADS-B and MLAT network!
