System Analysis for a Kinematic Positioning System Based on the Global Positioning System

Abstract

This report documents the findings of a study to design a kinematic positioning system to support U.S. Army Corps of Engineers dredging and hydrographic survey operations. Survey quality GPS receivers are considered, due to the accuracy constraints (10 cm vertical positioning). Use of auxiliary sensors (i.e., INS and high quality clocks) is considered to improve navigation performance when GPS is unavailable. Predicted navigation performance indicates that the accuracy requirements can be met, except at the extremes of the expected separation distances from the reference station. The integer ambiguities associated with the carrier phase measurements can generally be resolved within 7 minutes by processing all available satellites. Measurement gaps of roughly 60 seconds can be tolerated without losing the integers when using a high quality INS....
