TAMPA, Fla. — Beyond Gravity is weighing expanding solar array drive mechanism production in Florida to support Golden Dome and other U.S. space projects, after doubling manufacturing space in Europe for hardware that keeps satellites pointed toward the sun.
The Zurich-headquartered space systems supplier said Oct. 15 that expanding to 225 square meters of cleanroom space in Switzerland has delivered a fivefold increase in output, enabling production of 200 mechanisms per year amid growing demand for sovereign constellations in Europe.
“This year alone, we have already delivered more units than in the past three years combined,” said Oliver Grassmann, Beyond Gravity’s executive vice president of satellites.
Grassmann said European demand is being driven by IRIS², Europe’s proposed sovereign multi-orbit broadband network, and other planned constellations aimed at strengthening regional independence.
In the United States, Beyond Gravity serves domestic space primes from a 2,000-square-meter facility in Titusville, Florida, and anticipates surging demand linked to Space Development Agency constellation efforts and Golden Dome, the country’s multibillion-dollar missile defense initiative.
Grassmann said the company has another 2,000 square meters of reserve space at the Titusville site near Cape Canaveral.
“In Titusville, we have highly automated our manufacturing and are able to achieve similar efficiency gains like in our newly expanded cleanroom in Switzerland,” he told <em>SpaceNews.
Beyond Gravity supplies a variety of solar array drive mechanisms for spacecraft ranging from microsatellites to large Earth observation and telecommunications platforms.
Customers include NASA’s Artemis lunar program and the European Space Agency’s Hera planetary defense mission that launched in October 2024.
Meeting demand
Alongside the growing importance of space capabilities, shifting market dynamics and the broader industrialization of satellite manufacturing are driving Beyond Gravity to accelerate production of solar array drive mechanisms.
“We expect satellite lifespans to be shorter than in the past due to the prevalence of constellations,” Grassmann said, pointing to a broader shift toward high-volume manufacturing to support rapid replacement and upgrade cycles.
Beyond Gravity is also developing a modular two-axis solar array drive mechanism designed to let solar wings continuously track the sun in more directions, boosting power generation amid the rapidly changing lighting conditions of low Earth orbit. The company says the system could be combined with the company’s existing single-axis products.
One of the biggest challenges in space missions is ensuring a continuous power supply to satellites and spacecraft, according to Alexandra Isele, vice president of mechanical satellite solutions at Beyond Gravity.
The performance of photovoltaic modules can vary significantly depending on the type of solar cell and technology, she said, with specialized multi-junction cells used in space reaching about 30% efficiency.
“By continuously adjusting the solar panels to face the sun, our mechanisms can significantly enhance this efficiency,” she added.
“While standard commercial photovoltaic modules typically have an efficiency of around 15-20%, our mechanisms can help achieve efficiencies of up to 50%.”
Isele said the mechanisms also enable satellites to achieve maximum power output from smaller solar panels.
“Without solar array drive mechanisms, solar panels would need to be significantly larger, leading to higher production and launch costs,” she said.
Beyond Gravity, which is already supplying a two-axis solar array drive mechanism for the NASA Artemis Orion crew capsule, expects to make its new modular system available for orders by mid-next year following further testing.
