Abstract: The results of a land semikinematic or stop-and-go test, conducted under normal operational conditions to assess the performance of a high-accuracy and multipath resistant new C/A-code receiver technology, are presented. This type of test was selected to provide an accurate assessement of both the carrier phase and code data under static and kinematic conditions. The control points determined with the phase data are in agreement at the centimeter level with the values determined by a conventional GPS survey. The double-difference code residuals, which are affected by measuring noise and multipath, were found to behave in a quasi-random manner, with an estimated standard deviation of 50 cm. The effective multipath rejection characteristic of the receiver is attributed to the use of a narrow correlator spacing in the code tracking loops. Kinematic positioning tests based on code and carrier phase-smoothed code measurements using the between-receiver single-difference technique resulted in 1 m and 50 cm RMS accuracies, respectively, in each of the three coordinates. These accurate results will assist in the effective implementation of rapid carrier phase ambiguity resolution techniques for both the static and kinematic cases.
