3-metre GRID antenna and ground station

Silurus

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.

SZESAT-1

1U CubeSat in Earth orbit

Our first own satellite reached orbit on 28 November 2025. Its onboard systems transmit telemetry on UHF, which the ground station in Győr receives and archives on every pass.

Frequency band
UHF 435–438 MHz
Mass
≈1,3 kg

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.

EME

Moon-bounce communication and radio astronomy

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.

Frequency band
