The EXA DMSA/1 (Deployable Multifunction Solar Array for 1U) is the upgraded version of the latest DSA 1/A, it is EXA's entry level product of a family of deployable solar arrays based on artificial muscles for CubeSats in the range of 1U to 6U. The arrays fold into a panel attached to the CubeSat structure just as another solar panel and once in orbit it deploys to full extension, it includes deploy and release contact sensors and its own deploy control board.

It includes embedded antennas that range from VHF to L band. The DMSA antennas are embedded in its structure as 2 monopoles or 1 dipole and they deploy with the solar array.

The DMSA also has an embedded magnetorquer, sun and temperature sensors. It is possible to configure different solar cells like EXA low-cost solar cells or AzurSpace 3G-30 for very high-power missions. The maximum folded thickness is 6.25 mm for the 3-panel array.

Every array is tested and qualified in EXA's facilities and it is shipped with full reports.
