Problems in GPS Accuracy
… finding methods for detecting and repairing cycle-slips in range delay data between a satellite and a receiver. The distance between a satellite and a receiver can be estimated by measuring the difference in the carrier frequency phase shift experienced between the satellite and receiver …

Factors That Affect the Global Positioning System and Global Navigation Satellite System in an Urban and Forested Environment.
… the contributions to the accuracies from cycle slips, multipath, satellite availability, PDOP, and fixed or float solutions were evaluated. Three points in the urban environment varied from the conventional data set. Multipath was assumed to be the major bias in these points. Seven points …

GPS kinematic positioning for the airborne laser altimetry at Long Valley, California
… phase observables must be used and the integer-cycles of phase ambiguity must be resolved. In this thesis, we investigate the ambiguity problem in different situations and develop different ambiguity strategies depending on the situation. Firstly, we develop a position-independent …

Optimising Signal Isolation and Phase Measurement in Digitally Enhanced Interferometry
… comprising this measurement experience numerous cycle slips and cannot independently track phase. We further demonstrate the ability of this technique to perform these measurements under the noise dynamics of a broad linewidth diode laser. Overall, this thesis presents three advancements in …
