Key highlights
SARA is an autonomous, fail-safe, high-performance Solar Array Drive Assembly (SADA) designed specifically for SmallSats, supporting power ranges from 100W to 5kW. With its innovative redundancy systems and advanced sun-tracking technology, SARA ensures uninterrupted payload availability and optimizes solar array exposure, doubling power generation compared to fixed arrays and vastly boosting platform capabilities and mission returns.
Applications
Revolv Space’s SARA is tailored to diverse SmallSat missions, from Earth observation to communication and scientific research. As an agile alternative to established suppliers, Revolv Space specializes in delivering reliable and cost-effective solutions with low-lead times, addressing urgent industry needs and aligning with the business models of large constellations.
Key features
