| 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 |
