Kinematic GPS Results without Static Initialization

Benjamin W. Remondi

Abstract:	The kinematic Global Positioning System (GPS) technique, developed between 1983-1985, has delivered centimeter- level trajectory determination as promised. This has been satisfactory for survey operations because the static initialization process, to establish carrier phase integer ambiguities, is acceptable. The author discusses an approach developed in early 1990 which allows the initialization step to be accomplished while in motion. This paper focusses on results achieved from late 1990 to the present. Numerous kinematic experiments have been performed. Using the kinematic receiver, the operator periodically visits a known survey monument so that, during postprocessing, kinematic truth will be known. Typically, a reference receiver is situated close (less than 1 km) to the rover receiver, and other reference receivers are situated at remote sites (e.g., 13 km). The data are then processed using “kinematic GPS without static initialization”. The resulting trajectory is compared against the truth trajectory to verify that correct integer lanes have been isolated and to determine the accuracies achieved at the various experimental distances.
