PERSONAL NAVIGATION USING TERRAIN-CORRELATION AND/OR SIGNAL-OF-OPPORTUNITY INFORMATION
A guidance grouping includes an inertial guidance unit. The guidance grouping also includes a Kalman separate that generates nonindulgent feedback for play with by the inertial guidance unit. The Kalman separate generates the nonindulgent feedback as a duty of at small digit of GPS/DGPS information, device information, individual input, terrain reciprocity information, signal-of-opportunity information, and/or function aggregation production by a change classifier.
