Abstract : A program was conducted to design and develop a feasibility model of a Tacan Bearing-Distance Measuring Equipment for use in an improved navigational aid flight inspection system, referred to as SEAL (Signal Evaluation Airborne Laboratory). The purpose of the Tacan portion of the flight inspection system is to evaluate the quality of a signal emanating from a selected Tacan ground facility. This purpose is accomplished by use of a highly accurate Tacan Bearing-Distance Measuring Equipment such that the data obtained is representative of the characteristics of the radiated signal. In-flight monitoring and recording of the data permits subsequent data reduction and computation of the quality of the Tacan signal to a high degree of accuracy. The design consists of independent bearing and distance measuring equipments, providing for simultaneous data collection and position updating. (Author)
