Barometer

  • MS5611

  • BMP388

  • MS5611

  • Used to calculate altitude based on pressure.

  • Using a barometric pressure sensor vs. GPS :

    • Doesn’t rely on orientation

    • Doesn’t get fooled if you are flying over something

    • HARDER to use due to aerodynamics principles (Bernoulli's principle)

GPS

Airspeed Sensor:

  • UNKNOWN MPN

...

  • Possible issues that come with GPS

    • Large error bound

    • Slow update rates (1Hz)

    • Signal interference (weather, etc.)

Ultrasonic

Airspeed Sensor

  • UNKNOWN
