Moon-bounce communication and radio astronomy

EME

In our EME experiments we receive signals reflected off the Moon, and our radio astronomy measurements study the radio emission of the Sun and the Milky Way.

Silurus

3-metre GRID antenna and ground station

Silurus is the backbone of the lab: automated azimuth-elevation tracking with an in-house motor controller and position control. This is where we talk to SZESAT-1 and to amateur radio satellites.

Diameter

SZEppelin-1

Stratospheric balloon and airship experiment

A self-built payload lifted into the stratosphere: live telemetry, an onboard camera and environmental measurements. Analysing the recovered data is a core part of our student research work.
