Lighter steering systems enabling lower-cost satellites
In Space, Every Gram and Watt Matters
Every satellite manufacturer must reduce size, weight, and power (SWaP) to decrease cost and increase range. With excess SWaP, there must be more fuel, structural support, solar panels. Every excess kilogram adds about $25,000. With the steering system being one of the heaviest subsystems, it's of critical importance to reduce SWaP in this area. That's where Aphelion comes in.
Aphelion is targeting satellites that use ion thrusters to move.

Why Aphelion
Revolutionary spherical motor technology delivers unprecedented improvements in satellite control systems when compared to conventional small satellite electric propulsion pointing mechanisms.
84%
Volume Savings
Our compact design reduces spacecraft volume requirements by 84%. This is due to the removal of complex linkages, enabling more efficient payload configurations and mission flexibility.
29%
Power Reduction
With only four electrically active components, we achieve 29% less power consumption compared to conventional technology. This dramatically extends mission duration and reduces operational costs.
70%
Mass Reduction
Revolutionary 8-component design achieves 70% less mass than traditional systems, while maintaining superior performance and reliability standards.
