SVN
We use Subversion to keep hold of all our project material - reference documents, design documents, program code, schematics, simulations, mathematical models etc...
You can browse through the repository online using the very basic web-interface - just click on the repository URL: http://svn2.assembla.com/svn/SEDSAT-2
See the general SEDSAT-2 SVN page for an introduction to and setup instructions for SVN. In the SEDSAT-2 SVN database, there is a directory called "comms". This is where all the Communications team stuff goes! Within the "comms" directory, there are two important directories: "docs" and "design".
- In the "docs" directory, we keep documents written by other people eg. design reports from other cubesat projects, datasheets, reference manuals etc. Try to rename documents before putting them in here, to give them a meaningful name - the title of the document, the author and the date of publishing are good things to include in the file name.
- In the "design" directory, we keep everything generated by us. This could be MCU program code or it could be a design document detailing transceiver choices.
References
We keep all our links to our reference material on our SEDSAT-2 Communications References page.
