We have all heard the stories of drivers relying on the information from their SatNav system and ending up somewhere embarrassing that they wouldn't have dreamed about going if they were relying on their own navigational skills. Whilst many of these stories end up on the local news channel due to the entertainment factor, it should not be forgotten that some of the situations that can arise from false information from a SatNav system can turn out to be very dangerous indeed.
If you can recognise that problems like this do occur with even the most expensive SatNav systems you may be interested to learn about a new publication that has been released which tackles this problem head on. The publication is by that renowned expert on the subject of navigation, John Maris, and it is entitled, The SatNav Users Guide to Navigation and Mapping Using GPS.
It consists of 100 pages of information which will ensure that the reader will be aware of any of the problems that they may encounter with their SatNav and how to take precautions to ensure that any problems or misinformation are kept to an absolute minimum.
A wide variety of subjects are covered within The SatNav Users Guide to Navigation and Mapping Using GPS and in particular, the section on projections and datums is absolutely fascination and something of an eye opener, that is for sure. It must be said that the author has done a splendid job of making what is a very technical subject really interesting and he has written this publication in a way that anybody, no matter what their level of technical knowledge is, will be able to understand everything about it.
If you have any interest in this subject, if you are a driver you should do, then the SatNav user Guide is something that you really should investigate further.
