ARA Power and Communications Unit


Askar'yan Radio Array

The Askar'yan Radio Array's remote power nodes communicate with the main lab by a variety of means.  The Power and Communications Unit is a data aggregator.  The PCU communicates with different nodes by Ethernet or by RS-485 or by Zigbee radio, simultaneously.  Data from all nodes are aggregated into a single stream for transmission to the North by satellite.  Also, commands from the North are routed to the correct node.
