Spacecraft Power Electronics Products for over 30 Years

Spacecraft electronics of all types require a reliable and efficient power system, whether embedded, modular, or standalone. Without power, no mission is possible. 

Beyond Gravity has been a leader in the development and manufacturing of advanced spacecraft power electronics products for over 30 years.

Beyond Gravity is also active in the New Space segment, delivering high-quality Power Distribution Units (PDUs) to commercial customers. Our expertise in Power Conditioning and Distribution Units (PCDU) design is recognized industry-wide, and we have played a critical role in several high-profile missions.

Beyond Gravity's PCDU design expertise was utilized in ESA's ADM-Aeolus mission and the management of the Electrical Power Subsystem for the Solar Orbiter. We have also designed and developed PDUs for numerous other missions, including Venus Express, Mars Express, Rosetta (both subsystem and payload units), Swarm, Cryosat 1, and Cryosat 2.

Today Beyond Gravity’s Power Conditioning and Distributions are the most dependable in their segments, offering competitive prices and excellent performance. We are committed to providing our customers with the best possible products and services.

SCALE Power Distribution Unit for constellations

SCALE is Beyond Gravity's Power Distribution Unit (PDU) for both single missions and satellite constellations. It is a cost-effective and reliable solution for distributing primary power to payloads and heaters in spacecraft constellations. SCALE leverages the benefits of distributed payload solutions, offering SPF-free protection of the primary power bus and LCL protection of primary and secondary powers with configurable LCL limits.

SCALE supports CAN and RS-485 command interfaces, ensuring seamless integration with your existing systems. SCALE is built using Beyond Gravity's automotive-grade, TID and Heavy ION tested, EEE component library. Radiation-hardened components are incorporated in critical functions when necessary based on Beyond Gravity's comprehensive analyses. SCALE has established in-orbit heritage since 2025.

FLEX Power Conditioning and Distribution Unit

Flexible Power Management for modern satellites: FLEX is Beyond Gravity’s next-generation Power Conditioning and Distribution Unit (PCDU). It is designed to efficiently manage, control, and distribute electrical power throughout a satellite. Based on its modular architecture, FLEX can be tailored to a wide range of space missions, from smaller satellites to high-power spacecraft.

As the central element of a satellite’s Electrical Power Subsystem (EPS), FLEX ensures that energy generated by the spacecraft solar arrays is conditioned, stored in the batteries, and distributed safely to onboard equipment of a satellite.
