Key highlights
CShark provides an innovative combined actuator that integrates both a magnetorquer and a reaction wheel into a single compact product. This solution has been specifically conceived for seamless integration on PocketQube and CubeSat platforms, significantly reducing the overall integration effort for satellite developers. The unit incorporates all the necessary control equipment for both the magnetorquer and the reaction wheel, eliminating the need for additional external boards or complex setups. Designed with efficiency and simplicity in mind, the combined actuator requires only a 5V power supply and a standard I²C communication line to operate, making it highly compatible with a wide range of satellite architectures. By merging two essential attitude control technologies into one device, CShark offers a space-efficient, reliable, and easy-to-implement solution that optimizes performance while streamlining satellite assembly and mission preparation.
Key features
- Multi-format compatibility: developed to be integrated into satellites from 0.5U up to 6U and beyond,
- High-precision coil: the winding is performed with our automatic coiler, ensuring consistency and repeatability in the generation of the magnetic field.
- High bandwidth reaction wheel control: The rotational position, speed, and acceleration are controlled in a closed loop. This allows for a very precise and stable actuator with minimum jitter.
- Selected materials: use of low-resistance enameled copper wire, optimized to minimize ohmic losses and improve system efficiency.
