Ferrofluid flywheel
Know more about our experiment!
Meet us

We’re the group of students from AGH University of Science and Technology and Jagiellonian University. We prefer different fields of study and interest, but we are all connected by our passion to space. Two years ago we decided to launch our own science satellite. We spend free time and use knowledge to make our dream come true. In the evenings, after lectures, we make calculations, plans and seek for new solutions in order to succeed.

The most important units
Construction of the satellite
Ferrofluid is a suspension consisting of tiny magnetite molecules in carrier fluid. In our experiment we will use its strong reactivity to magnetic field.
Casing of experimental system
Experimental system is constructed from 7075 aluminium alloy and placed in special steel container. Electromagnets placed around the container puts the ferrofluid into motion.
Printed Circuit Board
The PCB elements were carefully chosen, so they can work properly in wide range of temperature. Work is controlled by STM32 microcontroller, which provides low power consumption with high computing power.
Data from the orbit
Due to accelerometer, gyroscope and magnetometer - sensors placed in KRAKsat – we will be able to observe its location in the orbit.
Flash memory
Regular data from sensors and log files from the experiment will be held in 8MB flash memory. During communication sessions we will receive information stored in memory.
Power supply
Satellite is powered by photovoltaic panels. They will be charged during flight around the Earth in the time of exposition to the Sun, which is 60% of the passage time.
