Space exploration has a great meaning for mankind. There are
\nmany space technologies that have been explored for space, but then
\ntransformed for human everyday use. One of such technologies is
\nGPS navigation.

This chapter provides an overview of the Global Positioning System (GPS) system, aviation augmentations, GPS avionics, and aviation applications. Code division multiple access (CDMA) is utilized for all the GPS navigation signals, that is, all of the satellites broadcast their signals upon the same carrier frequencies. GPS receivers determine their position and precise time using passive range measurements to visible satellites. These range measurements are obtained through a measurement of the transit time of the broadcast navigation signals and are referred to as pseudoranges since all simultaneous measurements may have a large common bias due to a low-cost receiver clock. GPS avionics used in general aviation (GA) aircraft fall into two main categories: integrated flight decks and panel-mounted GPS navigators. The GPS receivers themselves may be remote mounted and combined with very-high-frequency (VHF) omnidirectional range/instrument landing system and VHF communication receivers. Portable GPS receivers are commonly used in GA aircraft, sometimes sharing the cockpit with more traditional installed GPS equipment.

The Global Positioning System (GPS) is a satellite-based navigation
\nsystem made up of a network of 24 satellites placed into orbit by the United States Department of Defense (DOD) and managed by the United States Air Force 50th Space Wing. GPS was originally intended for military applications. It was designed
\nto assist soldiers and military vehicles, planes, and ships in accurately determining their locations world-wide. However, in the 1980s, the government made the system available for civilian
\nuse.
\nCivilian applications are evolving and expanding constantly. Today,
\nthe uses of GPS have extended to include both the commercial
\nand scientific worlds. Commercially, GPS is used as a navigation and positioning tool in airplanes, boats, cars, and most outdoor recreational activities such as hiking, fishing, and kayaking. In the scientific community, GPS plays an important role in the earth sciences. Meteorologists use GPS for weather forecasting and global climate studies. Geologists use GPS for surveying and earthquake studies to measure tectonic motions during and between earthquakes.
\nThe GPS is vast, expensive and involves a lot of technical ingenuity,
\nbut the fundamental concepts at work are quite simple and intuitive. The objective of this thesis paper is to give the readers a working familiarity with both the basic theoretical and practical aspects of how the GPS works. Chapter 1 introduces a condensed GPS program history that involves three competing concepts from the Transit, Timation, and Project 621B programs.
\nChapter 2 examines the GPS system consisting of three segments: space segment, control segment, and user segment. The three segments contribute to overall accuracy, reliability, and functionality. Chapter 3 outlines the basic mathematical methods used to calculate user???s position based on a system with no errors. Finally, Chapter 4 and 5 covers two important math theories needed to handle satellite and receiver clock errors:
\nNewton-Raphson Method and the Least Squares Method.

The Global Positioning System

Baker, Brendon · Utah State Research and Scholarship (Utah State University) · 2017

This research study explores the Global Positioning System (GPS), its history, and the process of discovery needed to create the most accurate GPS possible, as well as the contemporary applications of GPS technology. Starting with the first satellite in space, GPS has been a work in progress. Originally pursued by the military for improvements to military tactics, GPS has become integrated into the everyday lives of millions of people around the world. How GPS determines location is a dichotomy, with simplistic theory and complex application. Many factors go into GPS to provide a consistent, accurate location. The orbital planes the satellites are placed in provide 24/7 coverage globally, the L-band frequencies used were chosen specifically for the characteristics they possess, and the multiple atomic clocks installed on each satellite provide incredible accuracy down to the nanoseconds, which is quintessential in GPS accuracy. The applications in GPS are far reaching and more applications are continually being discovered. With as far as GPS technology has progressed, there are still several factors that degrade the signal and are a challenge to overcome. Many of these challenges can be corrected efficiently, however, others, such as scintillation and total electron content variability in the ionosphere, create major hurdles to overcome. Luckily, there are many programs that aid in the correction process of these hurdles.
