Abstract : The RHO-RHO Computer Display is a combined pictorial display and course line computer operating from three DME inputs. Its place in the overall pictorial display evaluation program is merited by the higher accuracy of DME as compared with previous VORTAC pictorial displays. The equipment employs several design techniques for realizing the inherent accuracy of the input data; among these are slant range correction, use of sophisticated station selection circuitry to automatically and continuously selec the two stations which yield tracking data of the highest accuracy, ambiguity resolution circuits and use of high grade components. A comparison of this instrument with a RHO-RHO-Theta Display previously developed for the FAA indicates that the present unit achieves a greater measure of operational flexibility, similar accuracy, and increased probability of system operation at the cost of additional functional complexity.
