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.
