The thesis deals with a navigation aid that plots the position of a rover on a map shown on the screen with reference to three ground-based references. The rover houses a receiver that would measure the signal strengths from three transmitters with different frequencies. Based on the signal strengths of the transmitters, the distances from the receiver to each of the transmitters is determined through a computer. These distances are then traingulated to approximate the location of the receiver relative to the three transmitters. A virtual map is created by interfacing the location of the transmitters, the triangulated location of the receiver, and a map of the site. The rover is capable of navigating itself to any specific point in the map using the three transmitters as a reference. The control system is from a PC and the vehicle/rover is connected to the PC through bus connection. The three transmitters would be equidistant from one another, since this gives the best accuracy of 9.2% from the experimentation. The distance from one transmitter to another is 7.5 m.
