On-Orbit Demonstration of Innovative Multifunctional Membrane Structure for Ultra-Lightweight Solar Arrays and Array Antennas by 3U CubeSat OrigamiSat-1

The 3U CubeSat OrigamiSat-1’s deployable membrane structure is 1m-by-1m in size after deployment and is stowed in less than 1U CubeSat (10cm-by-10cm-by-8cm), including a hold-and-release mechanism. The major significance of the structural concept is that it allows the attachment of thin-film devices, such as thin-film solar cells or flexible substrates for antennas throughout the membrane. This was achieved by two features: (i) use of textile and (ii) invention of hybrid boom made of tubular carbon composite and metal convex tape. In addition, a visual membrane measurement system consisting of stereo cameras was developed. This paper describes the new technologies developed for this CubeSat
