CougSat1-Readme

This contains links to every applicable file locating in the other repositories

CougSat1-Design gives an overview of CougSat-1

CougSat1-Requirements gives all of the system level requirements and subsystem design requirements

• Everything else

Hardware

The CougSat1-Hardware repository contains all engineering files that deal with hardware. Note: Every schematic's first page is the block diagram that abstracts the subsystem to blocks that should be understandable my most people (even without an electrical background).

• The Avionics board has the ADCS. C&DH, and IFJR subsystems.
  • Avionics schematic
  • Avionics design document
• The Backplane board connects every subsytems in parallel.
  • Backplane schematic
  • Backplane design document
  • CougSat card standard is the mechanical design of the cards that slot into the backplane
• The Ground station talks to CougSat-1
  • Ground station schematic
  • Ground station design document
• The Payload is a germination experiment and a camera that will take photos of Earth
  • Camera Payload schematic
  • Camera Payload design document
  • Germination payload schematic
  • Germination payload design document
• The Power subsystem handles all power for the entire craft
  • EPS schematic
  • EPS design document
  • Solar panel schematic
  • Solar panel design document
• The Radio board communicates for CougSat-1 to the Ground. The +X Panel mounts the low gain antenna.
  • Comms schematic
  • Comms design document
  • +X Panel schematic
  • +X Panel design document
• The Structure holds all of the hardware together
  • Structure design document
• The Umbilical connects to CougSat-1 for testing and charging when the sun goes away
  • Umbilical schematic
  • Umbilical design document

Software

The CougSat1-Software repository contains all engineering files that deal with software

• The ADCS µController controls the ADCS
  • ADCS software documents
• The Comms µController controls the Comms subsystem
  • Comms software documents
• The Ground application runs on a normal computer and talks to Comms
  • Ground software documents
• The IFJR µController controls the IFJR subsystem
  • IFJR software documents
• The IHU controls the C&DH subsystem
  • IHU software documents
• The PMIC controls the EPS
  • PMIC software documents

Resources

The Resources repository contains all engineering files that are not directly related to CougSat-1. These are supplier documents, general how to build a satellite resources, etc.

• Cougs in Space Inventory has every hardware component with its sku, model number, vendor number, and current quantity
• Component models has mCAD for every hardware component
• CubeSat specifications has the governing CubeSat specifications
• Example cubesats has documents from various succesful CubeSats
• Standard Operating Procedures has documents that aid in standardizing the engineering efforts
• Subsystems has resources files that are specific to a subsytem
  • EAGLE Files has the EAGLE resource files (CAM, DRU). The readme has the guidelines for creating schematics and boards.
  • Cougs in Space Library has all of the EAGLE library files. The readme has guidelines on creating a part in the library. Anyone can make a part but it may be easier to have Bradley make it.
• Supplier Documents has datasheets and other documents about commerical hardware (i.e. anything we do not fabricate)
• Templates has template files for various applications
• CubeSat 101 is a long document made by NASA that gives a starting guide to how to build a satellite.
