The Canadian Coast Guard and Atlantic Pilotage Authority will continue testing indefinitely virtual and synthetic AIS aids to navigation in Halifax harbour, from two locations:

1) A synthetic AIS AtoN atop the current fixed aid at Oceanographic Wharf, Bedford basin, 44 40 50.7905N 063 36 50.9277W; and
2) Four virtual AIS AtoNs located at: 44 33 35.960N 063 30 39.040W; 44 30 20.958N 063 30 18.062W; 44 33 05.961N 063 30 39.040W; 44 33 20.960N 063 31 00.018W. The diamond pattern is oriented true North and the distance between cardinal points is 0.5 NM.
