However, now I am stuck with the question what the standards are for mounting hardware in cubesat structures.
Although the CubeSat ICD specifies the external dimensions, there is no standard size of PCB or mounting scheme. Each university will come up their own internal arrangement, mounting scheme, and internal connectors, when designing their structure.
Some groups will use the off-the-shelf CubeSat Kit from the folks at Pumpkin. http://www.cubesatkit.com/ They may buy the Pumpkin structure and/or electronics, so they will design their custom modules to be compatible with that. So, if you wanted your transponder design to be ready to drop-in to a CubeSat Kit, you should follow their board-outline and mounting points. You can get the specifics from the CubeSat Kit Breakout Board Datasheet: http://www.cubesatkit.com/docs/datasheet/DS_CSK_Breakout_Board_711-00380-A.p...
The folks at The Stensat Group, designed a 2m/70cm transceiver for Libertad-1 and their fit theirs on a Pumpkin CubeSat Kit form-factor PCB. See http://www.stensat.org/satellites.htm
I hope you find this information of use.
