MaSat-1Budapest University of Technology and Economics
MaSat-1 is a CubeSat project of the Budapest University of Technology and Economics, Budapest, Hungary (in Hungarian abbreviated as BME and in English as BUTE). The goal is to introduce undergraduate students to circuit design, as well as to train a sufficient number of space specialists, thus facilitating future selection processes for spaceborne developments. The mission objective is to demonstrate various spacecraft avionics, including a power conditioning system, transceiver and on-board data handling.
MASAT-1 decayed on 09.01.2015 around 22:35 UTC.
MaSat-1 complies to the 1U CubeSat form factor of size 10 cm x 10 cm x 10 cm and a mass of = 1 kg. The objectives of the CubeSat mission are:
- Demonstrate an EPS (Electrical Power System) designed and built by students, which includes 6 independent MPPT (Maximum Power Point Tracker) for each solar array.
- Test Lithium-Ion Polymer batteries used as energy storage in space environment
- Test a new communication system based on an ISM (Industrial, Scientific and Medical) band transceiver
- Test a packet telemetry and telecommand concept based on ESA standard (ECSS-E-70-41A)
- Demonstrate an on-board data handling system based on a single board computer using digital signal processor
- Demonstrate a semi-active magnetic stabilization system based on magnetic torquers. The attitude is sensed by: 3-axis gyroscopes, 3-axis magnetometers, 3-axis accelerometers, and sun sensors made of IR sensors.
The CubeSat has an expected lifetime of > 3 months, the EPS provides an input power of 1.2-2.2 W.
