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
