Title:
ALTITUDE MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2023020040
Kind Code:
A
Abstract:
To provide an altitude measuring device capable of making measurement accuracy excellent while keeping down calculation load.SOLUTION: An altitude measuring device (1) according to the present disclosure includes: an atmospheric pressure sensor (5); and a calculation unit (4) that acquires, as an atmospheric pressure initial value (P0), an atmospheric pressure measurement value measured with the atmospheric pressure sensor when power is turned on, sequentially calculates an amount of change (ΔP) in the atmospheric pressure measurement value measured with the atmospheric pressure sensor, sequentially calculates an amount of altitude change (Δh) based on the atmospheric pressure initial value and the amount of change in the atmospheric pressure measurement value, and calculates an altitude (h) based on accumulation of the amount of altitude change.SELECTED DRAWING: Figure 1
