Abstract —The inertial navigation system (INS) is a very fast system and produces data at a high data rate while the global positioning system (GPS) receiver is slower than the INS. Hence, there is a gap between the two systems reading data. For GPS/INS system integration, synchronization must be provided between them, to make it possible to compare the reading data of both systems. In this paper, the sampling rate difference between GPS and INS is solved by predicting or extrapolating the missing reading data of the GPS to be compatible with those of the INS data using adaptive fuzzy system (AFS).
