Abstract : The purpose of the evaluation was to examine the concept of using a manpack receiver in a hyperbolic navigation system by employing a prototype Manpack Receiver (Minidec). Objectives selected included the feasibility of the concept to fix the geographical position of ground troops, rendezvousing of aircraft with the ground troops, and the sutiability of the Minidec for its design purpose. The equipment was employed by the 5th Special Forces Group and 9th Infantry Division under various operational and environmental conditions in Vietnam. The accuracy of the hyperbolic system is dependent on the distance from the transmitter and its physical environment. Helicopters were able to fly to the Minidec site when given the coordinates. The concept of land navigation is valid but areas of dense foliage and uneven terrain made it difficult to receive signals from the transmitters. The Minidec, in its present configuration, is unsuitable for use in RVN. It is recommended that no action be taken in procuring the Minidec system for use in RVN. (Author)
