From the standpoint of custom phonesat implementations there is a significant software automation-set for phone design with virtual and hardware in the loop simulation. You can change the frequency, the modulation, the codes, the operation modes (act not just as a client but as a peer to peer or even as a base station), bandwidth, etc. Modern phones use direct convert digital to and from RF. Meaning there are no limitations other than a top frequency of the converters used. This means that new designs using latest components can be rapidly used and designed and built in less than 6 months.

Origami Solar Power arrays. http://www.redorbit.com/news/space/1113213424/origami-for-space-solar-power-arrays-081514/The example in the video above was for 65W cubesat array. Compare this to CAT thruster mission examples below using a 25W array, about 0:30 mark.http://www.ustream.tv/recorded/46819252
This is first of SmallSat conference 2014 videos I've seen, only just be placed on Youtube. Hopefully more will fully.Please post any you view, along with a short summary plus the video title.Small Sat 2014: Keynote Steve JurvetsonSteve Jurvetson is one of the commercial space industry's most successful investors. He is a partner of Draper Fisher Jurvetson, First part is about SpaceX, followed by a little history of PlanetLabs.Besides his investments in SpaceX he is also backing some small sat launches, didn't mention any names but I'm guessing companies like RocketLab and Firefly.
Another video on Michigan Engineering's CAT plasma thruster. With 7 kg payload a 6U cubesat can reach Jupiter in 3yrs from C3 for <$10M per cubesat. This is why planetary scientists are very interested/excited by the advances in smallsat and cubesat technology.
Cyclops Smallsat deployer for ISS. This is due to fly on CRS-4 later this month.3th Sept 14 article. I couldn't open then Zip file as it is password protected. If somebody knows the password or has a link to video it would be appreciated. The mp3 file is OK.http://spirit.as.utexas.edu/~fiso/archivelist.htmHere is paper on the Cyclops plus its first 2 payloads. http://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=2941&context=smallsat
Has anyone ever flown a CubeSAT with propulsion?
