I'm sure many of you will be familar with the CubeSat project, in fact some of you may well have worked on one.
So lets hear it, what would you do with a 10x10x10cm 1kg payload in a CubeSat, beside the obvious like stick a camera in it and photograph your house. Who knows, perhaps one day we may see the launch of the USF CubeSat |

With Clyde Space now having announced a space-rated EPS for the CubeSat Kit, we have a more complete overview of the available masses and volumes for missions that base their satellites on our hardware. Here are some interesting numbers:
Structural masses (i.e. the masses of the complete empty structures of our CubeSat Kits, including all fasteners): 1U (10x10x10cm): Total for 1U solid-wall: 251g Total for 1U skeletonized: 166g 3U (10x10x30cm): Total for 3U solid-wall: 521g Total for 3U skeletonized: 321g FM430 Flight Module (C&DH and COM processor): 81g Microhard MHX-series transceiver: 66g Solar Panel Clips: 9g Clyde Space EPS (includes Li-Poly battery, estimated): 250g So excluding payload, antennas and solar cell panels, a 1U skeletonized chassis + FM430 + MHX transceiver + Clyde Space EPS comes in at 572g, and uses up roughly the lower 45mm of the internal volume in the structure. So that means that you have roughly 400g for the antenna(s), solar panels and payload, and room for the payload inside a volume of roughly 96 x 96 x 40mm. The real killer -- mass-wise -- is the Solar Panels themselves. Just the bare PCBs (in 0.062" / 1.5mm thickness) weigh 30g each. So 180g just to be able to mount your solar cells to panels on all six sides. Dropping to 0.031" (0.75mm) PCBs saves you nearly 100g (10% !) of mass of the satellite. I noticed in this thread some discusson of the 2U (10x10x20cm) CubeSat. We've built and delivered 1U and 3U (solid-wall and skeletonized) units to customers. Haven't yet received an order for a 2U (or a 0.5U or a 1.5U), but all of these are easily implemented within our architecture. Hope this helps, -------------------- ______________________________________
