Abstract

A relationship between reader arrangement and DOP is derived from the geometry matrix of the TDOA-based position tracking system. It is shown that the minimum value of the DOP is affected by the number of readers, arrangement of readers and position of the tag. The relationship is verified through computer simulations for two cases of reader arrangement.
