Revolv Space, headquartered in Torino, continues to advance the portfolio of Solar Array Drive Assemblies (SADAs) engineered specifically for small satellites and CubeSat-class missions. The company develops compact, lightweight and high-efficiency rotational mechanisms designed to optimize solar energy generation by enabling dynamic Sun-tracking capabilities in orbit. As satellite missions demand higher onboard power for advanced payloads, onboard computing and communication systems, fixed solar panels increasingly limit available energy. Revolv Space addresses this challenge with precision drive assemblies that rotate solar panels to maintain optimal orientation toward the Sun with improving energy capture and overall mission performance.

Revolv Space’s Solar Array Drive Assemblies are engineered to provide single-axis rotation for deployable solar panels, allowing spacecraft to maximize power generation throughout the orbit. The systems are designed to be compact and compatible with standardized CubeSat and small satellite platforms. The drive assemblies incorporate space-qualified motors, bearings and control electronics designed to operate reliably in vacuum, radiation and temperature extremes. By integrating rotational capability without significantly increasing mass or volume, Revolv Space enables small satellite operators to enhance power budgets while maintaining form-factor constraints.

SARA: Compact and Lightweight Solar Array Drive

SARA (Solar Array Rotation Assembly) is designed specifically for CubeSat-class platforms where volume and mass constraints are critical. The system enables deployable solar panels to rotate along a single axis, ensuring consistent Sun-pointing capability during orbital motion. SARA’s compact form factor allows integration within small satellite structures without significant redesign. The system is engineered to provide precise rotational control and efficient torque management, ensuring stable operation over extended mission lifetimes. Its lightweight design supports missions requiring enhanced power availability without compromising launch mass limitations.

HOLLY: High-Performance Solar Array Mechanism

HOLLY is developed to support higher power demands in small satellites requiring greater torque capacity and robust structural performance. The mechanism is engineered to accommodate larger or more complex solar panel configurations while maintaining efficient rotational precision. HOLLY incorporates enhanced mechanical robustness and power handling capability compared to entry-level systems. The drive assembly is designed to withstand launch loads and dynamic space conditions, offering reliable performance for satellites requiring increased energy generation for payload-intensive missions.

MARA: Modular and Scalable Solar Drive Solution

MARA is a modular Solar Array Drive Assembly designed for flexible satellite architectures. Designed to accommodate varying panel sizes and mission profiles, MARA supports scalable integration into diverse spacecraft configurations. The system emphasizes adaptability, allowing satellite manufacturers to customize panel configurations based on mission power requirements. MARA’s architecture balances mechanical strength, rotational accuracy and operational durability, ensuring compatibility with extended mission durations and evolving satellite power demands.

Revolv Space’s Solar Array Drive Assemblies are designed to operate with high positional accuracy and minimal backlash, ensuring stable Sun tracking and optimized energy capture. The systems are engineered to function reliably under radiation exposure, vacuum conditions and thermal cycling typical of Low Earth Orbit (LEO) missions. By integrating rotational drive capability into compact assemblies, the company enables small satellites to achieve higher power efficiency compared to fixed-panel configurations. This is particularly valuable for missions involving advanced communication payloads, onboard processing systems, Earth observation instruments and data-intensive applications. Revolv Space’s SARA, HOLLY and MARA assemblies provide flexible solutions that support higher power budgets without significantly increasing spacecraft size or mass. Through precision mechanical design and compatibility with standardized satellite platforms, Revolv Space contributes to improving the energy autonomy of next-generation small spacecraft.
