OBC

Onboard Computer. It is the brain of the satellite which handles all the internal communication, controls subsystems, creates telemetry data packets and processes telecommands sent from our ground station.

SPA

Spectrum analyzer. Instrument that measures human caused electromagnetic pollution. Two types of analyzer can be found on the satellite: a hardware and a software radio based.

CAM

Camera and navigation subsystem. MRC-100 features a 5 MP camera that takes compressed jpeg images. On the same panel, we put a GNSS receiver that provides accurate coordinates which are transmitted in the telemetry.

ACS

Attitude Control Subsystem. Magnetic Attitude Controller using three perpendicular magnetorquers. Two of them use a ferromagnetic core and one uses an air core coil.

STX

S-band transmitter. Provides a high speed downlink for the telemetry in the S-band at 2267.5 MHz

LSW

Limiter switch. Acts as a smart swtich for each subsystem, protecting them from overvotage and overcurrent and it also provides real-time current measurement.

AIS

Automatic Identification Subsystem. AIS is a vessel tracking system, developed for terrestrial use, but its range can be extended by using satellite repeaters.

SUN

Sun and Earth horizon detection subsystem as part of the ADCS.

TID

Total Ionizing Dose meter. RadNano is the smallest, low power dosimeter on the market.

SZEGED

There are two experiments on the satellite provided by the University of Szeged. One of them compares different temperature sensors in space environment and the other module has been developed by students containing a collection of smaller experiments.

GYŐR

The experiments of Széchenyi István University focuses on validation of their microcontroller modules.

DEBRECEN

University of Debrecen has developed an experimental, FLASH memory based dosimenter. It uses the violation of data integrity that happens due to ionizing radiation.
