Changes for 0-G Flight

Things We Don't Need to Worry About Anymore

• Torque on satellite
• Oligo shutting us down
• Authority budget with Oligo

Unchanged

• Still need to use thermocouple data
• Still need to spin motors, speed may change
• Still need to collect readings
• Still need to monitor pressure
• Still need to monitor fault detection
  • Safe mode still must occur for angular rate too high, multiple sensor failures, bus voltage or battery state-of-charge below minimum, persistent control residuals

Differences

• May need to take commands from ground team?
• Our fault detection may need to be more robust, given that Oligo won't be shutting us down/sending us into SAFE mode at all.
• Safety considerations are different; failure is less expensive
• Uplink/Downlink power considerations may change
• Overall power budget may change
• No low-power attitude mode
• No safe mode for attitude determination failure (no attitude determination
• No authority budget

Small Note: Arduino can be used to interface with STM32 MCU's using this library: https://github.com/stm32duino
