STDDS SMES


Summary

The FAA SWIM Surface Movement Event Service (SMES) publishes data from the ASDE-X infrastructure installed on the surface of ATD-2 participating airports. Received messages are a list of PositionMessages which are batched and persisted to a PostgreSQL database at a configurable time interval. The PositionMessages are also forwarded to the Fuser. Below is a resource guide on where to get more information on STDDS SMES . Much of the information is available on the FAA NSRR which requires users to register an account (available to the general public):
