Investigations of C/A Code and Carrier Measurements and Techniques for Rapid Static GPS Surveys

Code and carrier measurements and techniques for rapid static GPS surveys are investigated. Developments are based on using only single frequency carrier phase data with high accuracy C/A code measurements. Theory of GPS observables, least squares solutions and preanalysis as applied to GPS is reviewed. Solutions using code measurements, carrier measurements and code-carrier measurements combined with up to five minutes of data for 720 m and 4.1 km baselines are analyzed. The ambiguity function method, the fast ambiguity resolution approach and the least squares ambiguity search technique are each investigated as means for ambiguity resolution in rapid static surveys. Although each of these methods is shown to be negatively affected by code or carrier multipath, they are shown to be successful within certain constraints. The investigations made in this thesis are important to the objective of achieving centimetre accuracies in minutes using rapid static GPS surveying techniques.
