Short summary
In 2013 the scientists from the geophysical centre in Dourbes started a project to install a fully automated observatory in Antarctica. The ultimate aim is to have real-time data coming in to Dourbes every second. After evaluation of different data transfer protocols, we chose to use Message Queuing Telemetry Transport (MQTT) and receive the 1 s data with a negligible latency cost and no loss of data.
