RMS Noise Calculations

Altimeter, MS560702BA03: 

At OSR of 4096 - RMS Noise = 0.024 mbar

Pressure at 14k ft (90° F): 614.2733 mbar

Pressure at 15k ft (90° F): 591.5817 mbar 

614.2733 - 591.5817 = 22.6916 Δmbar 

22.7 / 1000 = 0.0227 mbar/ft 

1 / 0.0227 = 44.05 ft/mbar 

0.024 X 44.05 = 1.058 ft = 322.375 mm RMS Noise Near Apogee at 90° F

Altimeter, BMP390:

At High Resolution and IIR Filter Coefficient of 128 - RMS Noise = 0.03 Pa

Pressure at 14k ft (90° F): 61427.33 Pa 

Pressure at 15k ft (90° F): 59158.17 Pa

61427.33 - 59158.17 = 2269.16 ΔPa 

2269.16 / 1000 = 2.27 Pa/ft

1 / 2.26916 = 0.44 ft/Pa

0.03 X 0.44 = 0.013 ft = 4 mm RMS Noise Near Apogee at 90° F

High G Accelerometer, ADXL375:

Noise = 5 mg/√Hz

5 mg * √100 = 50mg Noise at 100 Hz ODR

5mg * √ 200 = 70.7mg Noise at 200 HZ ODR

5mg * √3200 = 282.8mg Noise at 3200Hz ODR
