Figure 3

Proportion of test positions with measured error from 1 to 10 m. Percent of positions with accuracy equal to or less than each measured value for the mobile tag test (circle), stationary tag at location one (triangle), and the stationary tag at location two (square) depicted an array with most positions having accuracy better than 6 m. The average error of the unfiltered data for the stationary tag at location one (1.98 m), location two (1.11 m), and the mobile test (6.83 m) are marked by representative symbols along the x-axis.
