Applications of PNT Systems

Chapter

Abstract

The tremendous growth in this industry is driven by the enormous number of applications provided by GPS and the other GNSS systems. These are far beyond what was originally designed and envisioned to be a strictly U. S. military system. Providing extremely precise, three-dimensional timing and navigation in a worldwide common grid that can be easily converted to any local mapping coordinate system has created huge new commercial markets and new scientific and public benefits. GNSS allows for continuous, passive, all-weather operation of an unlimited number of users anywhere on Earth, up to low-Earth orbit. But we cannot deny that GPS is vital to national security needs, and GPS is an aspect of almost every U. S. military activity. It is the same for Glonass and the Russian Federation, and will be so for China, India, Japan, and the EU.
