Never before was it so crowded on board a missile. When the Indian carrier rocket PSLV („Polar Satellite Launch Vehicle“) left the Indian spaceport Sriharikota in February 2017 the mission was to launch 104 nano-satellites into the orbit. This extraordinary mission was successful and even tops the previous world record. And - myonic is part of it!

The „Cartosan Tow Series Programme“ is the most complex space mission the Indian space authorities ISRO (Indian Space Research Organization) have ever launched. The difficulty in this rocket launching was - astonishingly enough - not the size of the individual satellites in the rocket - they only measure a few centimeters and only weigh a few kilogramms - but to bring the 104 satellites collision-free and in the stipulated order into the orbit.

After 17 minutes this complicated action was executed smoothly. The released nano-satellites will send important information to the earth such as e.g. "biros" of the German Center of Aviation and Space Technology which were developed in order to trace forest fires.

Some of these satellites use myonic miniature ball bearings which were developed in a lengthy qualification process together with ISRO.
The usual method for the three-axis stabilization of satellites is the installation of a momentum wheel. The myonic ball bearings used must be of utmost precision and treated with a super-finish grinding process in order to work without friction for a long period of time (> 15 years) at the most varying temperatures .
Positioning and power supply are essential for a satellite. Solar panels are used for supplying power. In order to bring the solar cells into the right position multiphase motors are used which vice versa are equipped with myonic specialized ball bearings.

myonic is proud to be in a position to supply ball bearings for these very critical applications.
