# How 4DSKY Works

Neuron nodes turn the Airsquitter sensor into a network node that can be connected to directly by 3rd party software. Both nodes and the explorer are connected to the Hedera testnet that provides a range of decentralised services that ensure the network remains open, and community governed.

​Any software applications (customers) can connect to your sensor directly or obtain data feeds via the 4DSKY Edge software.

The 4DSKY network comprises of 3 key user interfaces:​

* Customers: such as the [4DSKY](http://www.4dsky.com/) Flight Tracking Software
* Service Providers: such as the Jetvision Airsquitter Sensors
* Explorer: Registration System & Discovery Service
