Abstract

Abstract: A micro radio localizer that can be used in micro systems such as Micro Aerial Vehicle （MAV） is proposed.Localization principle is discussed in detail.Under the assumption that the electromagnetic wave obeys the free-space spreading model，the measuring equations are established.The determination of several factors of the localization error such as the number of measuring positions and measurement errors is discussed.A radio-localizer prototype is developed and experiment results are shown as well.

Key words: radio localizer, passive localization, error analysis, Micro Aerial Vehicle（MAV）
