A reconnaissance sonde to be dropped and erected in an area for wirelessly transmitting data to a data processing apparatus. The sonde includes a housing having top and bottom portions; a parachute disposed at the top housing portion; a plurality of support legs peripherally mounted on the housing in a circumferential array and having a folded state and a deployed state; a drive for simultaneously moving the support legs from the folded state into the deployed state upon landing of the sonde; a GPS navigation system, a magnetic field sensor and an attitude sensor for accurately determining a position and an attitude of the sonde; at least three target bearing determining sensors supported by the housing and distributed circumferentially; an electronic evaluating apparatus supported by the housing and connected to the GPS navigation system, the magnetic field sensor, the attitude sensor and the target bearing determining sensors for evaluating measured sensor signals thereof; a transmitting and receiving apparatus connected to the electronic evaluating apparatus for wirelessly transmitting evaluated signals to a remote data processing apparatus or an additional sonde; and a battery for supplying electric energy to the sonde components.
