GPS and Amateur Radio
By Walter Fields, W4WCFOrder #4932 ..... $18.95
The Global Positioning System (GPS) is a satellite-based, radio navigation system. GPS has improved the way we navigate, communicate, and move about the planet. With this book, you’ll explore GPS: its history, how it works, and navigating with a GPS receiver. We’ll also examine how Amateur Radio operators have made use of GPS technology. A popular ham radio application is in the Automatic Position Reporting System, or APRS*. By connecting inexpensive GPS receivers to their radio gear, hams transmit their positions and other information, which is then displayed on maps at the receiving stations. The result is an effective method of direction finding for public service activities such as search-and-rescue—and for fun! ©2007 A.R.R.L.
