Blue: represent antennas which signal is actually received (i.e. not lost) at a given time
Yellow: represents the estimated point using all data from the antennas
Light Blue: represents the estimated location using median on the last SIM_WINDOW simulations (last SIM_WINDOW yellow circles)
Orange: shown on the antenna that gives the strongest signal at a given instance of the simulation
