All navigation information can now be used jointly and optimally, and the integrated navigation system has become standard navigation tool. This research involved the analysis and investigation of navigation systems (mainly the GPS and integrated navigation systems) and navigation computation for high precision navigation and attitude determination, especially for marine application. The emphasis of the research was to find new methods and concepts to deal with the traditional navigation problems. The navigation models were analyzed in both time and frequency domains and the model's stability; controllability and observability with GPS observables were introduced in order to facilitate the navigation filter design. New kind of filters, such as frequency-discriminating filters and separated-bias Kaiman filter, were introduced to navigation data processing, and these filters are useful for GPS data smoothing, cycle slip detection and repair and ambiguity resolution in both static and kinematic modes. Based on the navigation system and equipment operation and error analysis, a closed-loop dead reckoning integration with other navigation systems (GPS, Omega, Loran-C and radar) was proposed in order to obtain a good system frequency response and facilitate the body's manoeuvre detection and system quality control. To use GPS potential efficiently, a new GPS observable "Doppler created phase" was introduced and associate algorithms were developed. This new observable can be used in both static and kinematic positioning (if the data rate is high enough) using low-cost navigation receivers (output C/A code and Doppler only), and theoretically an accuracy of equivalent to a phase-floatingambiguity solution can be expected. Extensive analysis was given to the attitude determination using GPS, and its limits, potential and alternative implementation are also presented. The software development and data processing validated the proposed theory and algorithms. The results and statistic tests were illustrated by the different kind of plots including the correlograms and periodograms.
