Overview

4DSKY has developed a framework based on the Neuron SDK, that is utilised in all of its products. This section will describe the framework, its principals and core components.

4DSKY is the founding architect of the Aviation Data Exchange (ADEX), which is an open-source, edge-native aviation surveillance data distribution model designed to support real-time airspace situational awareness, driven by the requirements of high performance, secure, fault tolerant, and digitally native drone operations. The system architecture is built on the foundational premise that both servers and clients function as independent actors, coordinated through a series of functional systems as defined below:

Servers advertise their capabilities, operational metrics, and service-level parameters to the ADEX directory service, enabling clients to select them according to mission-critical constraints. Clients can authenticate, subscribe, and validate data feeds over secure point-to-point links, benefiting from edge-level fault tolerance and local control of data.
