Why PubSub+

PubSub+ enables diverse systems to publish information and services, request and receive information when they need it, and subscribe for automatic receipt. This ensures that airspace users and controllers always have timely information about situations that affect their area of responsibility, while reducing infrastructure costs, by decreasing the number of unique interfaces between systems.

Unlocking the benefits of ANSP modernization with PubSub+

A flexible and robust messaging layer can unlock a variety of benefits for modernizing ANSPs

  • Reduced time and effort to introduce new services to the system, without disrupting existing ones
  • Easy automation of the real-time collection and distribution of a variety of information (flight, weather, surveillance, aeronautical data) to a wide range of stakeholders
  • Ability to route massive amounts of information between large numbers of endpoints, and automatically adapt to volatility and peak volumes
  • Simplified third party access to select data feeds (get many data feeds with a single connection using standard protocols like JMS, AMQP and MQTT)
  • Better interoperability, locally and globally, with other ANSPs through SWIM
  • Industrial strength reliability and performance
