ABSTRACT:
This invention discloses apparatus for linearizing the relation between altitude and an output signal of a sensor which represents the n th power of atmospheric pressure by means of generating a basically exponential signal of a parameter and obtaining the corresponding value of the parameter at which the exponential signal coincides with the output signal of the pressure sensor. This invention also includes means for measuring an accurate altitude by correcting the above linearized value according to the standard atmosphere adopted by the ICAO by means of generating a function for compensating the effect of temperature distribution of the standard atmosphere.
