Applied GPS for Engineers and Project Managers introduces civil engineers¿especially those who are not already licensed surveyors¿to the fundamental principles of global positioning technology (GPS). This book covers GPS basics, including positioning and measuring principles, techniques to improve accuracy, and an analysis of low-cost versus high-precision systems. Subsequent chapters explain the considerations for selecting and implementing a GPS system and then demonstrate specific applications of GPS in a variety of engineering situations, including monitoring the health of structures, robotics and machine control, maritime operations, material tracking in large construction sites, site control and design, and monitoring geohazards. This book will be valuable for all civil engineers interested in benefiting from the use of GPS technologies.
As more and more individuals have to travel for work, travel and a myriad of other reasons, it has become somewhat of a priority to have the best technological device to help them get from one point to the next. As a result of this GPS Units have become exceedingly important, especially for those who are on the road on a daily or weekly basis. That is why "How To Pick The Perfect Portable GPS Unit" is a must for every consumer. Gone are the days when printed maps are used to find out just which way to go, not to mention that they tend to become outdated pretty quickly as more and more changes are made to the infrastructure. In this day and age electronic devices are needed to help the user to select the fastest route to their destination. They are pretty user friendly and can easily be updated.
Today, increasing demands and expectations are being placed on GPS systems. Assisted GPS (A-GPS) has been developed to provide greatly improved capabilities, helping GPS work better and faster in almost any location. Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. The book reviews standard GPS design, helping professionals understand why GPS requires assistance in the first place. Readers discover how A-GPS enables the computing of a position from navigation satellites in the absence of precise time - a topic not covered in any other book. Moreover, engineers learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity of a GPS receiver.
