The Joint Tactical Information Distribution System (JTIDS) is a secure data and voice command, control and communication system. Developmental Test and Evaluation of the Class II JTIDS terminal in F-15 aircraft and ground stations will be conducted during 1985/1986 at Eglin AFB, Florida. As part of this testing, performance of the JTIDS RELNAV relative navigation function will be assessed, including a particular focus on stability and accuracy. As an aid to this assessment, VERAC, Incorporated, in coordination with U.S. Air Force Armament Division personnel, has developed and implemented a post-flight performance assessment and error allocation software tool called the JTIDS Test Data Optimal Processor (JTIDS TDOP). JTIDS TDOP utilizes advanced numerical techniques to implement an extended Kalman filter-based navigation smoothing algorithm which integrates test data from JTIDS, from the F-15 INS, and from test-range tracking instrumentation. The system produces best estimates of aircraft trajectories and croresponding measures of JTIDS RELNAV performance. These results permit not only an assessment of compliance to system specifications, but also a detailed validation of predicted error budget analyses, based on the use of actual test data.
