Amateur Radio CubeSat Masat-1 takes first pictures

Masat-1, the first Hungarian satellite, made history again
when it captured the first satellite space photographs on March 8, 2012

The first photo showed the southern section of the African continent
followed by photos of Australia and Antarctica.

Besides their sole beauty, these photos also demonstrate the careful
planning and execution of the satellite’s operation, proving that even
within the tight mass and energy constraints of Masat-1 it is possible
to capture space images.

Masat-1 is the first Hungarian satellite, designed and built by
students and lecturers of the Faculty of Electrical Engineering at the
Budapest University of Technology and Economics in cooperation with
the Hungarian Space Office and various domestic companies.

The satellite, measuring 10x10x10 cm and weighting 1 kg, was launched
by the Vega launch wehicle of the European Space Agency (ESA) from the
spaceport at Kourou in the Caribbean. Masat-1 along with seven other
student built amateur radio satellites were deployed into a 1441 by
310 km orbit.

The satellite has been operating flawlessly since the launch of
February 13, 2012, steadily transmitting data to the primary ground
control station (Budapest University of Technology) and the secondary
ground control station (Érd, Hungary). In addition to these domestic
control stations, more than 120 radio amateurs have received the
satellite worldwide. Their total contribution to the success of the
mission exceeds 200 000 data packets.

The on-board camera of Masat-1 has a mass of about two Euro coins. The
maximal resolution is 640×480 pixels. A width of 1 pixel corresponds
to a distance of 1 to 10 kilometres on the photos recorded.

The call sign of Masat-1 is HA5MASAT and the telemetry transmission
frequency is 437.345 MHz +/- Doppler shift, which at worst case could
be +/- 10 kHz.

The Masat-1 Ground Station Client Software was prepared to process the
GFSK 625/1250 bps transmission received from the satellite Masat-1.

The software provides the following functions:
- Audio demodulation
- Packet decoding
- Packet data visualization
- Frequency waterfall plot to aid radio tuning
