Choosing a GPS

Picking the right GPS largely depends on the way that it is to be used. GPS has moved into the mainstream over recent years, and the price and usability of the systems have become much more accessible for people from all walks of life.

What is GPS

GPS stands for Global Positioning System. Although the workings of systems are complex, involving a series of 24 satellites and various calculations using different variables, the end result is really quite straightforward in that it is easy to pinpoint a position. When this is combined with other features and facilities, the GPS can provide a system that helps with navigation, works as a route planner or which tracks people and objects. This latter aspect of GPS is becoming more frequently used with cars being fitted with GPS tracking devices that are activated in cases of theft.

Types of GPS

The first step to choosing a GPS is deciding how you want to use it. There are different types of GPS in common use:

Street Navigators

One of the most popular types of GPS is the street navigation system or sat-nav (satellite navigation). Navigation systems are used in cars to help with directions and as a route planner. Although, again, the technologies are extremely complex, the end result can be described as having your own personal and accurate map reader sitting alongside you.

Most navigation systems come preloaded with maps of a given area or country. As well as allowing accurate directions, many navigation systems also include points of interest (POI) which include fuel stations, cash points and parking. This can help significantly when traveling in an unfamiliar area.

Most in-car navigation systems are updated via the internet, and this means that any system upgrades or new information is loaded directly onto the device. Maps of new regions and areas can be purchased which is great for travel. Another feature of many navigation systems is that they can also act as hands-free phone devices, which reduces the number of dashboard gadgets in the car. Navigation systems typically offer both text and audio instructions and these can be available in a choice of languages.

One of the downsides of navigation systems is that they have become a target for thieves and devices should be removed from the car when the car is left unattended. More information about GPS navigational systems can be found at the following websites:

• TomTom - the website of the international navigation system manufacturer. This includes a helpful product picker facility and explanation of different features. The website is international and visitors can choose their country upon entering the site.
• Garmin - in depth information about how GPS works and product details.

Sports

Many sports people find GPS useful. There are a wide range of different GPS devices specific to different sports. More information about these and useful websites can be found below.

Golf: Golf GPS systems include distance finders.

• Caddy Aid - extensive website including product comparison chart.
• Golf Logix - compatible with both PC computers and Apple Macintosh computers.

Fishing: GPS mapping helps fishers find suitable fishing spots.

• Chuck Hawks - an explanation of how GPS systems help fishers.

Hiking, Sailing and Cycling: GPS is useful in cycling, sailing, hiking and walking activities both as a mapping tool and as a safety device.

Pets

Some new developments in GPS technology have allowed tiny GPS systems to be incorporated into pet collars. This allows pets to be tracked if they have roamed or been stolen. While these systems are still expensive, they are a useful way of tracking and finding a faithful friend.

• Roameo For Pets - website of the manufacturers of a GPS system for pets. The website includes a useful FAQ section.
• Global Pet Finder – information about the system, including how to set up the system.

Tips for Choosing a GPS System

• Research different GPS systems by looking through websites and talking with specialist sales staff in stores. Don’t forget to read user reviews on websites such as Amazon.com, which can give an extremely useful insight into a product.
• Check prices carefully on websites and in stores. Often, if the price is too good to be true there is probably a catch! In particular be careful of second hand equipment; it could be flawed or from a dubious source.
• Ask around for recommendations. Internet forums are a great place to ask for advice, particularly in specialist areas. This can be a good way to help determine a short list of GPS devices to research further.

GPS is becoming an increasingly important part of day to day life.
