Ambiguity search strategies in rapid static surveying are discussed and some modifications are explored. Based on the assumption that the impact of the periodic multipath error on code and carrier phase measurements can be minimized by averaging the observations, an attempt is made to estimate the site occupation time in order to correctly resolve the integer ambiguities using spectral analysis in postprocessing mode. The relationship between code and carrier phase multipath is investigated. For single frequency users, an ionospheric model is developed by using code and carrier phase measurements. The accuracy of this model and results of baselines by applying this model are analysed.xi, 102 leaves ; 30 cm.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
