The Global Positioning System (GPS) provides position, velocity, and time information to users in anywhere near the earth in real-time and regardless of weather conditions. Since the system became operational, improvements in many areas have reduced systematic errors affecting GPS measurements such that multipath, defined as any signal taking a path other than the direct, has become a significant, if not dominant, error source for many applications. This dissertation utilizes several approaches to characterize and model multipath errors in GPS measurements.1.1 Introduction A Global Navigation Satellite System (GNSS) provides position, velocity, and time information to ... 1.2 Previous Work Code multipath in GPS signals has previously been characterized for a variety of ground- based receivers.
