World's tiniest satellite attitude control system
Reaction Sphere
hOW IT WORKS ?
Controlled by a patented magnetic field design, spherical motor is capable of spinning in X, Y, and Z axis. Moreover, bias-currents are applied on each phases of the motor, this enables us to combine 3-axis magnetorquers into this device as well.
X-AXIS
Y-AXIS
Z-AXIS
Product features
– Max. angular momentum: 20 mNms
– Max. Torque: 5 mNm
– Max. Power Consumption: 3 W
– Capable of providing angular momentum in X and Y axis simultaneously; Providing Z axis angular momentum independently
– Compatible to PC104 connector and various CubeSat architecture
Mission
Statement
Nowadays, space industry has faced two major obstacles, rocket and satellite costs. To tackle the second problem, satellite minimization is the key. Among all sub-systems, attitude control devices is the one last component that can’t shrink its size due to physical limitations. Thus, we develop this spherical motor technology in order to replace three motors by one. Within our unique design, this device can have 1/3 weight, size, and power consumption compared to traditional system. Finally, we believe we may enable space industry for a wider commercial applications by this invention!
