Characteristics of Altitude Error at Reduced Quantization.

Abstract

This report describes an analysis of the impact of reducing the quantization level on the altitude error produced by the aircraft's altimetry system. Specifically, the mean and the standard deviation of the altitude error at the output of the aircraft's onboard quantization device are derived assuming altitude error at its input is normally distributed. The formulae derived are very general, exact, and applicable to all ranges of input statistics and quantization levels. A computer program has been written to evalute the impact of reduced quantization levels. Additionally, a comparison is made between the commonly used and approximate uniform distribution model method and the exact formulae derived in this report for calculating the quantized altitude error. Keywords: TCAS(Traffic Alert and Collision Avoidance Systems).
