GPS: Theory, Practice and Applications
Frederic G. Snider, R.P.G.
The Global Positioning System (GPS) has revolutionized the fields of navigation, mapping and surveying. It is now routinely possible to know your location within about 10 meters (30 feet) anywhere in the world with inexpensive, hand-held commercial GPS receivers. It is also possible to use GPS for surveying at sub-centimeter accuracy, for control and monitoring of construction equipment and agricultural machinery, guidance of autonomous robots, and aircraft, vehicle and marine navigation.
This course provides an explanation of how the GPS system works, sources of errors, and methods used for improving the basic accuracy of the system, including Differential GPS. The wide range of GPS applications are reviewed and the main types and features of GPS receivers are discussed. The terminology used in manufacturer’s specification sheets is explained so you can compare various units. Finally, the course summarizes what you, the potential user, needs to understand in order to select the appropriate equipment for the intended use. As such, the principles and concepts presented here are equally useful to all types of engineers, constructors, architects, contractors, building inspectors, surveyors, scientists, and the general public.
The course outline is presented below:
The course is approximately 40 pages long including one Table and 17 Figures. A glossary of the most commonly used terms and acronyms is provided as a reference document. A multiple choice quiz is available online.
This course includes a multiple choice quiz at the end, which is designed to enhance the understanding of the course materials.
the end of this course, you should understand the operation of the GPS system
at a level sufficient to use GPS receivers for navigation and general positioning
applications. You will be familiar with the meanings of the words and acronyms
most commonly used in GPS literature, sales brochures, and manufacturer’s specification
sheets. You will know what questions to ask potential vendors about their GPS
equipment and how to decide what features you may need for your intended uses.
You will also be familiar with the sources of error affecting GPS accuracy,
how to improve the accuracy to the level you need, and the options available
for accessing Differential GPS corrections.
