Table 6 Formulae for calculating mean position of a tag in two dimensionsduring a time intervalΔtfor observation-weighted Simpfendorfer et al. and model-weighted positioning estimators using arithmetic and harmonic approaches
Symbols: n = number of receivers in the array; Ri = the number of receptions at the ith receiver during time interval Δt; Xi = the X-coordinate of the ith receiver; Yi = the Y-coordinate of the ith receiver; ωi = weighting factor, ωi = (max(di)/di), where di = model-estimated tag distance, di=f(Ri), from the ith receiver and max(di) = the farthest estimated tag distance from any of the detecting receivers.
* Harmonic means corrected from Simpfendorfer et al. .
