Roccor is developing a family of elegant deployable structures that reduce space asset cost by integrating high strain composite materials into low-part-count and high-performance-per-weight designs.
Gaining penetration into the emerging “new space” markets demands technologies that break “old space” price paradigms while maintaining “old space” quality and performance standards.
Our ROC (Roll Out Composite) Booms are cost-effective furlable composite boom products that deploy antennas and instruments from small satellites enabling a new generation of satellite constellations to provide ubiquitous science measurements and communications from space.
ROC Booms achieve this through a simple, low-cost, highly stable composite construction utilizing strong yet flexible thin-gage carbon-fiber composite shells that can be rolled onto a spool for packaging and un-rolled on-orbit for deployment.
ROC Booms from 1m to 5m in length have been delivered to our customers for applications including deployable/retractable camera systems, deployable antennas, and instrument booms.
Some nanosatellite designers want to deploy extremely large systems from very small volumes, and yet demand simple low-cost designs. For these applications, ROC Booms may be too limiting.
With up to 10 times greater deployed bending stiffness than traditional ROC Booms the TRAC (Triangular Rollable And Collapsible) Boom was originally developed by the Air Force Research Laboratory, and is now exclusively available from Roccor for applications demanding this unique combination of compact stowage and deployed strength.
Metallic TRAC Booms were originally flown on NASA’s Nanosail-D2 mission in 2010, and Roccor is currently developing very long lightweight composite versions for applications including solar sails, dipole antennas, and deployable tethers.
Sharing many of the same desirable features as our ROC Booms, TRAC Booms offer design flexibility to better meet the wide-range of needs emerging for low-cost, high-performance boom systems.
Space Solar Arrays
Roccor’s position as a trusted supplier of high performnce space Solar Arrays was confirmed in 2018, as Roccor signed a contract to supply a U.S. Government Customer with a >2 kW deployable Solar Array for an upcoming ESPA-class mission.
This customer required an unprecedented amount of solar power to be incorporated into a very small launch envelope. The close working partnership between Roccor’s experienced engineering staff and the U.S. Government mission team enabled an expedited development cycle, where Roccor’s High Power Solar Array for Small Satellites (HiPASS) array solution has been optimized in parallel to the spacecraft design.

Building on Roccor’s strength as an agile supplier of highly reliable Solar Array solutions, the PlanetIQ team signed Roccor to a contract to design, develop, manufacture and deliver two deployable 150W Solar Arrays for the initial PlanetIQ spacecraft. This commercial endeavor will culminate with delivery of the flight arrays, with a fresh sheet of paper design, less than six months after contract signature. Roccor’s ability to meet this extremely aggressive schedule enables our customer (PlanetIQ) to focus on overall mission success (and the rapidly approaching launch date), while keeping supply chain management of the solar arrays out of the critical path.
In addition to the growing list of near-term flight deliverable solar array programs, Roccor is actively partnered with commercial and U.S. Government Agencies in the development of advanced solar array architectures that directly enable a multitude of future mission concepts. In late 2018 Roccor signed a contract with the Air Force to develop the Atom Family of Solar Arrays. Atom provides a resilient power generation product line for future DoD constellations of small spacecraft. Similarly, Roccor and SolAero Technologies have partnered to commercialize SolAero’s COBRA solar array. This novel roll-out solar array solution enables both retractibility and a highly scalable architecture that maintains the performance and reliability of state-of-the-art photovoltaic cell technology.
