Graphically,
H: host
L1: Landmark 1
L2: landmark 2
L3: landmark 3
Using distance farmula:
D1= ?¯ (XL1- XH Xh)² ^2 + (YL1 - YH)² ^2 ............................................. (2)
FROM (1) & (2)
PD1= (?¯ (XL1 - XH )² ^2 + (YL1 - YH)² ^2) + ?t0 T0 . ? ? .................... (A)
Similarly for other 2 landmarks:
PD2= (?¯ (XL2 - XH )² ^2 + (YL2 - YH)² ^2) + ?t0 . ? .................... (B)
PD3= (?¯ (XL3 - XH )² ^2 + (YL3 - YH)² ^2) + ?t0 . ? .....................(C)
We need to linearize (A), (B) & (C) to solve them
