What To Look For In A GPS System

GPS has been showing the world the way to go for many years now. It uses satellite navigation via an electronic interface to help users find their way no matter where in the world they are.

Whether you are in a land vehicle, on sea or walking, a GPS system can be a valuable tool to help you identify your current position and tell you how to reach your destination.

GPS systems can be divided into four broad types – car navigation, portable devices, maritime units and GPS technology built into hand-held PDA systems. Once you have decided what is best for your purposes, you need to have a basic understanding of what to look for in your device.

Important features of a good GPS system include screen size and quality, interface, hardware accessories, correction capabilities, updated software, speed, battery power and voice quality.

Screen

You need to find a balance between screen size and resolution to enable you to see your position clearly from a variety of angles while driving, sailing or walking. Screens are measured diagonally and can be as compact as those of a mobile telephone, expanding to the size of a small television screen. The main requirement is the ability to see your position at a glance, with colour screens offering easier usability.

Interface

You need to be able the press the right buttons easily and without fuss. As with all interfaces, look for models that offer clean input and produces quick responses.

Hardware accessories

The most important accessory for a GPS device is the mounting hardware. This is crucial, particularly for vehicle use, which entails the ability to see the screen while driving behind the wheel or from behind handlebars on a motorcycle. The mounting also has to be secure and theft-proof.

The Daytoni MS3100R has a detachable panel for protection from theft and can easily be installed on a car’s dashboard or over the driver’s head.

Correction capabilities

GPS corrections, based on data received from different satellite signals, enable your device to enhance accuracy when it comes to establishing your position on the globe. You may need to purchase a correction antenna separately.

Updated software

You need to make sure the mapping software is up to date with physical changes to streets and landmarks around the world or your specified area. Ideally, the device should have the ability to download updated maps from the Internet.

The NAVMAN NAV ICN550TM is a stand-alone GPS unit that has the main roads of Europe as well as live traffic information.

Speed

It is important that you receive quick responses on your device when plotting positions. Just like a computer needs a powerful processor, find a GPS device with similar traits.

Battery power

The most reliable power source comes from your car, which can keep your GPS device charged while driving. Battery-powered units are excellent for walking but you need to know how long the power lasts.

Voice quality

Some GPS devices are voice enabled, which is particularly helpful for drivers who can receive voice navigation signals while keeping their eyes on the road.

Conclusion

It is clear that a bit of though must go into your purchase of an ideal GPS system. Identify which category you belong to and then target the specific features that is of most benefit to you before you make your choice.
