GPS, Positioning, Navigation, and Timing Satellites and Their Applications

Description

This two-day course will cover the origins, technical specifics, applications, and related issues involving Satellite Positioning, Navigation, and Timing (PNT) systems, also referred to as Global Navigation Satellite Systems, or GNSS. We will cover broadly the development of these systems, how they work, who operates them, and how they are used. We will also touch on the international policy and legal framework and future directions.

9. Conclusions and final thoughts

What You Will Learn:

You will learn, in a broad sense, what Positioning, Navigation, and Timing systems are, how they developed, how they work, what the different national systems are, and what they are used for. The course will provide basic information on the technologies, how we operate the space, ground, and user segments, how they have evolved over time, and where this is all going. You will learn the basic similarities and difference between the several national systems, and their primary applications. We will also cover the commercial market for this segment of space, including the major commercial trends, players, and markets. Finally, you will learn about the future, where this is all going, what are some of the revolutionary emerging technologies and how we are developing new systems for use on the Moon and beyond
