• Mission Commands
  • MCC uplinks ARO data (has to be encrypted) - 2 options (or send both up for redundancy)
    • Longitude and lattitude of ARO
    • Time when we will be over the ARO + roll angle for ADCS
    • Selfie-sat pass code
  • ARO uplinks selfie-sat pass (unencrypted)
    • Nothing, just the selfie-sat pass
  • QEYnet Mission (encrypted)
    • PING command to check if OBC is still connected to laser
    • Run mission command → on the next pass, turn on the laser, don't downlink telemetry
    • Turn off laser command (maybe mix into EPS commands?)
• Subsystem Direct Emergency Control Commands (encrypted)
  • CDH emergency: Command to reboot the OBC (On Board Computer)
  • EPS emergency: stop giving power to the payloads/to some subsystem?
    • Do we even have this capability? @Shreya Singh @Rakeen Lalani
      • Theoretically yes, we have an MCU, but I think we might have to mess with the architecture a bit?
    • yes (controlled by CDH) → it is our load switch circuit
  • ADCS emergency: satellite spinning out of control → send a manual detumbling command (maybe turn on all the magnetorquers?) (our torquers will always be on lol)
    • This command will not be sent by the MCC → it will be integrated into the ADCS code
    • Maybe need manual commands to have ADCS point in one direction?
• Other Subsystem Direct Control Commands (encrypted)
  • PID fine tuning for ADCS (why do we wanna do our PID fine tuning from the ground? seems like a bad idea → the only point to uplinking and downlinking "telemetry" for ADCS is either going to be the parameters needed to see if our )
• Startup commands (encrypted)
  • Any deployments?
    • Can't think of any manual ones
• Any firmware updates?
  • No
  • Should be able to change most things within configuration variables
• How will we update values like PID?
  • Update either a configuration file on FRAM (non-volatile memory) or change runtime variables
• TLE data
• Command to get telemetry data (might not need to uplink)
• Nothing specifically for ADCS, EPS

Downlink

• If we skip a pass, we should report it as an event in downlink data

Next Steps

• Think about actual format of packaging uplink commands
• Specifics of selfie-sat pass structure
• How we will implement encryption
