VZLUSAT-2

Experimental Earth-observation camera and high-energy particle detectors.

The primary payload of the mission is the experimental Earth-observation camera with an expected resolution around 30 to 50 m GSD.

Secondary payloads of the mission are Radiation Orbital Monitor, Gamma Ray Burst detector, X-ray detector and other sensors.

This mission is fully open to radio amateurs who were also involved in the development of the satellite.

The space segment uses two amateur bands for communication. An Sband for payload data downlink (DVBS2 ETSI EN 302 307 standard, 2 MBd, QPSK) and UHF-band for downlink beacon (GMSK 1200 Bd), telecommand uplink (GMSK, 1200 Bd - 9600 Bd) and telemetry downlink (GMSK 4800, 9600 Bd). 

The first part of commissioning included verification of the satellite platform systems, i.e., the power supply system, the UHF radio communication, and the on-board computer. Initial values of the satellite temperature indicated that the satellite was cooled down to -10 ° C, which was caused by its 11-day stay inside the deployer. After turning the satellite systems on, the temperature inside the satellite increased to operating temperature in the 0 ° C to + 10 ° C range.

In the second week after the deployment, gamma-ray burst detector for Masaryk University in Brno and Konkoly Observatory and X-ray solar cameras from Rigaku Innovative Technologies Europe and ADVACAM were turned on. Both devices have successfully performed the first measurements and are now also awaiting gradual commissioning.
