Figure 100: Given in red are two discrete linear trajectories of sensors x 1<br />

and x 2 in R 2 localized by algorithm (849) as indicated by blue bullets • .<br />

Anchors ˇx 3 , ˇx 4 , ˇx 5 corresponding to Figure 99 are indicated by ⊗ . When<br />

targets and bullets • coincide under these noiseless conditions, localization<br />

is successful. On this run, two visible localization errors are due to rank-3<br />

Gram optimal solutions. These errors can be corrected by choosing a different<br />

normal in objective of minimization.
