GPS Usability Over Functionality

Posted by admin on March 27th, 2008 filed in gpstechstore

There is an easy test that I like to use when evaluating a GPS, or any type of electronic device. I call it the user manual test. When I pick up a new GPS for the first time, I see how easily I can operate the GPS with common sense alone and without using the manual. Criteria for a good GPS is firmly based on how easily I can operate the menu options and pick up the functions. This is an aspect that some people overlook yet it is perhaps the single most important part of a GPS.

The first reason that user friendly functions and menus are so important is that the vast majority of people who buy GPS units are seasonal or occasional users. They are not out there 5 days a week, honing their skills and keeping the idiosyncrasies of their GPS at the forefront of their mind! Consequently, most users want to be able to pick the damn thing up and be able to get their hands on accurate information that can make the difference between getting lost, or even a fatal ending to an outdoor adventure.

The second reason that GPS units need to be easy to use is that they are often used by groups such as hunters, fishermen and hikers. This makes it quite likely that some members of the group will not be experienced with your particular model or brand of GPS. In these kinds of circumstances it is doubtful that anyone will want to sit down and read a user manual, that is if you still know where it is! So do yourself a favor and get a GPS that makes sense to you without having to go to the book, if for nothing else that from a safety point of view.

The third reason it that if you are willing to spend a couple of bucks on your GPS and choose a top brand such as Magellan or Garmin you don’t need to worry too much about what functions are included. The level of competition between these two companies is so high that neither is willing to put sub-standard products into the marketplace. At http://www.thegpscentre.com you can see reviews of GPS units and see how close these brand really are in both quality and price. What will make the difference will be the users ability to take advantage of the functions.

Remember, there is no point having a GPS with several navigation screens, thousands of automatic way-points if you can’t work out how to use them with ease. Happy trails and safe navigating to you all.

GPS and the Military

Posted by admin on March 16th, 2008 filed in gpstechstore

For those of us in the military, the humble gps unit is far more than a luxury, in fact gps is a necessity. GPS units allow soldiers and officers to get accurate and timely data such as location, altitude and time. In many cases, these rudimentary pieces of data would be almost impossible to obtain without the help of GPS technology, and can prove invaluable in real time scenarios, albeit training or the real deal.

GPS units have become an especially valuable tool in the context of indirect fire support. The ability to coordinate artillery and fast air support has been greatly enhanced with the advent of GPS. This is primarily due to the fact that GPS allows men in the field to accurately reference their position and hence calculate their proximity to targets. Essentially, this greatly reduces the inherent dangers of being on the ground during live firing.

Another aspect of GPS technology is that is has greatly increased the potential for command and control of soldiers. Real time LocStats and the ability to de-conflict a battle space are just two of the giant leaps that have been made possible by GPS. Many of the other benefits lie in target acquisition and the adjustment of offensive fire. Furthermore, GPS is quickly reducing the need for human adjustment of artillery as the combination of laser and GPS begin to realize their potential. The interfacing of these two tools is resulting in a degree of speed and accuracy that can scarcely be matched by humans.

One major criticism of the use of GPS has been the loss of field craft within the military. Due to time constraints and ease, the skill of navigating by map and compass is slowly being lost. The theory is that GPS units are used as a secondary tool to traditional navigation techniques, although in reality handheld GPS units have become a primary means of navigation for many soldiers. Simply walking in the direction that an arrow on an LCD display is pointing is becoming more common, but perhaps this is the face of progress. Moreover, in a game of life and death who can blame people for choosing speed and accuracy over tradition.
