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

  • Optimized for SmallSat & Microsat constellations
  • Autonomous operation: built-in sun tracking with embedded sun sensors
  • Dynamic power management: essential for constellation phasing and station-keeping maneuvers
  • Fail-safe for downtime reduction: Snapback system mechanically returns panels to a reference angle, minimizing power loss during failures
  • High efficiency: up to 2X power generation than fixed arrays, supporting up to 500W per unit
  • TRL 9 maturity: flight-proven and ready for rapid integration
