DMSA Micro: Deployable Multifunction Solar Array

The EXA DMSA Micro (Deployable Multifunction Solar Array for Microsatellites) is the upscaled version of the latest DMSA line, it is our answer to microsatellite sized products which are lightweight and thin, yet very robust and with a high power yield. The arrays fold into a panel attached to the spacecraft 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.

Now, in a world's first, it includes embedded antennas that range from VHF to S band, no longer you need to buy and manage antenna systems, the DMSA has them embedded in its structure as 2 monopoles or 1 dipole or a patch and they deploy with the solar array, you just connect the cable to your radio.

It also has an embedded magnetorquer, sun and temperature sensors. These solar panels feature a very high efficiency for very high-power missions; the maximum folded thickness is 19.5 mm for the 4-panel array. Every array is tested and qualified in our own facilities and shipped with full reports, the DMSA Micro yields the best results when coupled with our high-capacity batteries.
