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.

Densification surveys in New South Wales coping with distortions / D.A. Kinlyside (1992)

Public Titre : Densification surveys in New South Wales coping with distortions Type de document : Monographie Auteurs : D.A. Kinlyside, Auteur Editeur : Kensington [Australie] : University of New South Wales Année de publication : 1992 Collection : Unisurv Report num. S-42 Importance : 202 p. Format : 21 x 30 cm ISBN/ISSN/EAN : 978-0-85839-062-1 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes de référence et réseaux [Termes IGN] aberration instrumentale [Termes IGN] densification géodésique [Termes IGN] Nouvelle-Galles du Sud [Termes IGN] réseau géodésique [Termes IGN] transformation de coordonnées Index. décimale : 30.10 Systèmes de référence et réseaux géodésiques Résumé : (Auteur) This project reviews the traditional methods of estimating coordinates for points in horizontal geodetic densification networks within NSW (New South Wales). The primary control for these densification surveys consists of the station coordinates derived from the 1966 National Adjustment which have been assumed to be free of error. However, distortions in this primary control have become evident through the use of higher accuracy geodetic measurement techniques, such as lightwave EDM and space based positioning systems as well as improved methods of adjustment. The study quantifies the level of distortion in AGD66 within the confines of eastem NSW by comparing the existing coordinates with those estimated from a GPS network After transformation, the differences were found to be generally less than 0.5 metres, but systematic differences of about one metre appear in some areas of NSW. To demonstrate the effect of distortions propagating into secondary networks, a 300 x 300 km region in the central west of NSW was evaluated by combining all existing geodetic observations in a single adjustment. The theoretical aspects of several integration models, such as the weighted stations approach, were studied to determine their suitability for upgrading and densifying geodetic networks. The various models have certain compromises in either mathematical rigour or practicality. Numerical examples of the models are presented in which data is used ftom an existing primary and secondary densification network within the central west region of NSW. The problems involved in achieving and preserving the most accurate estimates for survey control coordinates in an operational environment are addressed. Particular attention is given to the least squares software capabilities, data management, network design and the analytical procedures currently used by the Land Information Centre, NSW Department of Lands. There is considerable scope for improvement in some of the present systems through the use of more effective data handling techniques. Future strategies for performing densification surveys in NSW will be significantly influenced by the trends in satellite surveying technology, the need for cadastral reform and the possibility of adopting a geocentric datum. The case for retaining the less accurate coordinates is compared with the acceptability of coordinate changes as new methods improve accuracy.

This is directed towards the Earth Deformation Studies (EDS) programme in New Zealand. The terrestrial, GPS, and deformation adjustment models are investigated. It is found that the parameters of vertical homogeneous strain are not well determined and that their estimation leads to difficulty in the interpretation of other deformation parameters. It is demonstrated that a 2D adjustment of triangulation data is suitable for combination with GPS for the estimation of horizontal strain but that a 3D adjustment is required for best results when EDM distances are included in the terrestrial data set. The GPS adjustment model is studied in detail, particularly some of the principal systematic errors (orbits, propagation delays and origin station coordinates). Simulations of GPS observation campaigns are used with errors rigorously propagated through to deformation parameters using the techniques of covariance analysis. The Kalman filter algorithm is employed as a means of dealing with dynamic variables and the equations of covariance analysis are developed in the Kalman filter setting. Strategies for selecting satellite and network geometry are compared using simulations. The effect of ambiguity resolution on deformation parameters is studied in detail. It is shown that the effect of tropospheric delay errors may be substantially reduced by estimation of residual zenith tropospheric delays. Where the tropospheric delay is time dependent, the Kaiman filter algorithm gives optimum results. Orbit estimation is studied using a simulated regional tracking station network and is found to significantly improve the accuracy of deformation parameter estimates. With dual frequency observations, and the estimation of tropospheric delay and orbit parameters, the effect of GPS systematic errors is insignificant compared to that of terrestrial observation errors.
