I am trying to build a cubesat using a Raspberry Pi. I am now figuring out how to communicate with it. As far as I know, I understand I will have to use VHF or UHF to do so.

How do I decide on the frequency to use?

How will frquency affect the cost?

How do I build an antenna to receive the signals?

Where can I buy its components for the Pi?

    $\begingroup$ There is a lot of literature and resources available just by googling. Please provide your research so far and make your question more specific. $\endgroup$ – Juancho May 5 '16 at 13:16
  • $\begingroup$ The last question "where can I buy its components" unfortunately falls into the realm of endorsement, and so is not appropriate on this site. $\endgroup$ – called2voyage May 5 '16 at 13:25

    $\begingroup$ I think this question is on topic here, as satellite design and operation is part of the scope. It's only for an educational project, but there may be some people here who can help with background such as comms protocols, etc. The questioner should add more detail about the nature of the project though, to attract better answers. $\endgroup$ – Andy May 5 '16 at 13:53
