REVIEW: THE AVIATOR'S GUIDE TO GPS by Bill Clarke TAB/McGraw Hill 1994
The NAVSTAR Global Positioning System, or GPS for short, is a space-based
radio-navigation system, developed by the U.S. Department of Defense in
the 1980s. It provides basic information on PVT which stands for position,
time and velocity. Originally available only to the military, modern
receiver techology has made GPS available to anyone. Hand-held GPS
radios are available for under $500.00 and are being used for many other
applications besides PVT, including measuring heights of mountains and
tracking wildlife. One of the more interesting uses of GPS is to interface
the receiver output to a computer's serial port and with suitable software,
you have a mapping program that actually tracks the movement of your
airplane, boat or car. More about that later!
It is not the intention here to explains the hows and whys of GPS technology;
rather to review a fine book on the subject. To be sure, it is a complex
subject and highly technical at that. Bill Clarke's book does a fine job
of explaining the theory of GPS, its history, hardware and so on. This
book, written for civilian aviators, is obviously aimed at pilots, but
it should also be of great interest to sailors, hikers and others who need
to know exactly where they are, their speed or even their altitude.
Aviators will find the chapter on alternatives to GPS navigation familiar
but it never hurts to review these principles, such as VOR. DME, NDBs, TACAN-
based systems, RNAV, ILS and even the old A/N radio beacons of the WWII era!
There are chapters on the FAA and GPS, airplane navigation with GPS and
moving maps that are driven by GPS. Finally there is a comprehensive
overview of aviation and hand-held GPS receivers on the market as of the
date of writing. Appendices include abbreviations, chart reference systems,
datums used around the world and federal policies and plans.
As mentioned earlier, one of the uses of GPS is to interface with a notebook
computer to drive a moving map. Peacock Systems' LAPMAP and other software
companies produce aviation moving maps that are quite remarkable. For
on-the-ground use, Delorme Mapping of Freeport Maine publishes MAPEXPERT
whose database contains every street in the U.S.A.and a GPS interface that
shows exactly where you are - right down to the block you're in!
Although quite technical in scope, Bill Clarke's fine book very ably
explains everything a pilot or sailor needs to know to understand GPS
concepts and to choose, install and use one of these very sophisticated
radio-location/navigation systems.
