P1=1st Landmark position (latitude, longitude)
P2=2nd Landmark position (latitude, longitude)
P3=3rd Landmark position (latitude, longitude)
d1= distance from 1st Landmark to target (Calculated using distance=(MinRTT/2)*alpha)
d2=distance from 2nd Landmark to target (Calculated using distance=(MinRTT/2)*alpha)
d3=distance from 3rd Landmark to target (Calculated using distance=(MinRTT/2)*alpha)
