Abstract: Method and system to ascertain location of drone box (100) for stabilized landing and charging of drones (10), comprising a plurality of drones (10) and at least a drone box (100) having a passive sensing circuit (149) detecting a touchdown signal of all the ground interface (11) of the drone (10, 10-1, 10-2) at a plurality 5 of sensor zones (111) for a minimum prescribed time, a detection of any missing touch down signal for the minimum prescribed time due to an inappropriate landing preventing next take off of the drone (10, 10-1, 10-2), the passive sensing circuit (149) prevents activation of any sensor zone (111) till all the ground interfaces (11) are detected as touched down, the sensor zones (111) 10 differentiates between presence of the ground interface (11) and any other presence including human touch, animal touch, foreign matter and or contamination and a combination thereof.
