Method and system to ascertain location of drone box for landing and charging drones comprising at least a drone box having a drone platform with a plurality of limiting boundaries, divided into number of sensor zones that are mechanically contiguous and electrically separated by an insulated separator of insulation width, each sensor zone having an identification coordinates, each drone having a plurality of ground interfaces, each having a unique address code, each ground interface has a charging terminal at a far end, each charging terminal having an interlocked switchable electricity polarity. The identification coordinates of the activated sensor zones are communicable to a second drone so that the second drone knows where NOT to land on the drone box, Such communication enables a third and subsequent drone to ascertain whether the identified drone box is suitable and available for landing.
