Kinematic Phase Processing Techniques in Support of Dredging Operations

G. Jeffrey Geier, Alfred Kleusberg, Stephen DeLoach

Abstract:	This paper examines the use of GPS kinematic phase processing techniques to support the real-time positioning requirements of dredging operations and hydrographic su~eying. The operations are first described. and the positioning accuracy and performance requirements necessary to support the operations are then d&cussed. Real-time. three dimensional, positioning with accuracies of less than 1 dectmeter are desired to improve earthwork computation for contract payments. In the vertical sense the desired accuracy will allow the vessel to seIve as its own tide gauge. Of primary interest is the ability of a kinematic-based system to acquire and maintain the correct set of integer ambiguities under the expected set of platform dynamtcs and signal obscuration. Simulation results will be presented which describe techniques that address three specific Issues of prlnxuy importance: the speed and reliability of integer ambiguity resolution: the degree to which measurement gaps can be overcome through the use of inertial aiding; and whether multiple reference stations are necessary to support operations.
