A Litton LTN-51 Inertial Navigation System augmented by two ARINC 568 digital DME's was flown in an FAA flight inspection aircraft for evaluation of updated inertial performance in the domestic area. The LTN-51 inertial computer received range inputs for two separate DME stations. The geographic fix of the two DME ranges was used to update the inertial system. Data was recorded automatically every four seconds and performance validated by comparison with flight inspection position calibration. 150 successful flight hours covering the Western United States were achieved in 2 1/2 months. Data shows deviation was 1,102 feet, 50%; 1,233 feet, 68%; 2,530 feet, 95%; and 3,499 feet, 100% (mean percentile points). Terminal approaches were also demonstrated. (Author)
