Abstract

An apparatus configured to obtain, process, and relay data to a user in a coherent and useful manner. An active fiducial 200 is equipped with an interface for receiving and transmitting data. The fiducial may transmit its position using a satellite-based position sensing device 204 such as a GPS. Active fiducials may also be equipped with battery power pack regenerated with solar cells 206. Similarly, the fiducials can be equipped with at least one video camera 208 or other device having a focal plane array and a computer software system, configured to recognize shapes. The fiducials may also be equipped with inductive coils 210 or other means for sensing metal containing compounds. The active fiducials may be equipped with a gas chromatograph 212. The active fiducials may use a variety of propulsion means including motor driven tracks 214, motor driven wheels 216, propellers, or other device or a combination of devices.
