Terrestrial Position and Timing System

Overview

The present invention relates generally to a terrestrial positioning and timing system (TPTS) that draws upon the heritage of current terrestrial distance, bearing, and positioning systems used in aviation, while incorporating new concepts for signal structure and implementation techniques to provide a terrestrial user position, navigation, and time (PNT) service. The TPTS also draws upon the concepts and techniques of terrestrial based differentially corrected pseudo satellites (“pseudo-lites”), using a modified code division multiple access (CDMA) Global Positioning Systems (GPS) signal format. The TPTS may be considered an alternative PNT service, for use when the GPS is not available.

The TPTS may be comprised of a TPTS ground segment with one or more stations and a user segment that may contain a plurality of TPTS users. The need for position, velocity, or time of a mobile user is not limited to aviation applications. Just as aviation users could use the TPTS station in times when a supporting GNSS is not available, other types of users, such as land, can use a suitably configured TPTS station to support its position, velocity, or timing requirement.
