An Assessment of the Absolute Accuracy of Long-Baseline Kinematic GPS Positioning of a Moving Vehicle

Thomas Henderson, Mark Leach

Abstract:	An experiment was conducted in October, 1989 to assess the accuracy of kinematic GPS in posi- tioning a moving rail car over baselines of up to 100 miles. High-order WGS-84 stations were used to reference the kinematic survey. The experiment compared carefully determined WGS-84 positions of test points along the centerline of a railroad test track with corresponding positions observed by a roving train-mounted GPS antenna as it passed over the test points moving at 60 miles per hour. Three-dimensional agreement at the sub-25-centimeter level was achieved, with consistent precision of better than 5 centimeters.
