A tracking system is used for observing or following objects on the move and supplying an ordered sequence of information, which in this case is the location data to a model, which is capable of providing display. As the name suggests, this tracking system is modelled using an antenna which is unidirectional, the YAGI-UDA. The antenna is designed so as to follow the motion of any air borne system with a frequency of 433MHz. The GPS coordinates are received in a timely fashion in order to control the antenna direction and motion, so as to make it unidirectional and limits its use as an omnidirectional antenna.
