Explore the Benefits of GPS

Explore the Benefits of GPS

GPS devices, sometimes referred to as GPS receivers, from companies such as Garmin, Magellan, and Navman, work anywhere in the world, 24 hours a day, in any weather condition. Once you buy a GPS device, you only need an unobstructed view of the sky to use it; you don't even need to subscribe to a service.

A GPS device receives data from a network of satellites in geosynchronous orbit around the Earth and uses the information to calculate your precise position. By locking into three satellites, GPS can tell you your latitude and longitude. With a fourth satellite in view, GPS calculates latitude, longitude, and altitude. Use GPS anywhere you need accurate data to help you navigate.

• GPS at work: Rescue crews, firefighters, archaeologists, geologists, surveyors, mappers, boat captains, pilots, dispatchers, tour guides, and military personnel use GPS devices to perform their jobs.

• GPS at play: Take your GPS device hiking, camping, mountain climbing, biking, snowmobiling, skiing, hunting, boating, fishing, touring, and flying so that you can find your way on land, at sea, or in flight.

• GPS on the road: Recycle all the maps in your glove box and put a GPS device in your car. A GPS device equipped with mapping software gives you street-level directions, which can prevent you from getting lost in a bustling city. It can also select an optimum route from point to point and help you make informed choices about where to stop along the way.

Determine Which GPS Device You Need

Determine Which GPS Device You Need

GPS devices fall into three categories:

• Recreational GPS: Take your GPS device everywhere. Handheld GPS units fit nicely in your pocket, backpack, or mount easily onto your dashboard. Some, such as the Garmin Forerunner, also come in a wristwatch-like design, perfect for hikers and bikers looking for a lightweight GPS device they can see at a glance.

• Automotive GPS: GPS devices built expressly for car use often include built-in maps or allow you to download mapping data. Many car GPS devices also provide voice directions so you can keep your eyes on the road, touch screens, and mounting options. Some examples include the Navman ICN models.

• Marine GPS: GPS devices designed for use aboard marine vessels and watercrafts boast a rugged waterproof design and may also float. Marine GPS devices often include onshore and offshore maps, chart-plotting functions, and a screen that's clearly visible in sunlight. Some even have the ability to predict tides or locate fish. One example includes the Garmin GPS Marine 276C.

Find the Right GPS Features

Find the Right GPS Features

GPS devices have a variety of features and options.

• Accuracy: Most GPS devices will pinpoint your location within 15 metres. If you need greater accuracy, look for differential GPS (DGPS), which calculates your location within 1 to 3 metres.

• Interface options: GPS devices come in a variety of screen sizes and may be monochrome or colour. Expect larger colour screens to cost a bit more than devices with a monochrome screen. Colour screens provide more detail, but use more battery power. When you look at item listings, evaluate the image the seller provides and make sure the screen looks like it works for you. When shopping for an automotive GPS device, look for touch-screen navigation, audible voice prompts for driving directions, and a trip computer. They will help you keep your eyes on the road, and the trip computer will let you know how much further you need to go when driving from point A to point B.

• Maps: Most GPS devices include built-in software such as street maps. You can also buy additional software, such as international maps for Europe or the U.S.

• Data storage: Many GPS devices come with built-in maps, but you can store even more if your device supports removable Secure Digital or CompactFlash memory cards. Mapping data doesn't take up a lot of space and many units even come with a 128MB card.

• Combination GPS units: Standalone GPS devices work great for most people, but some personal digital assistants (PDAs) and two-way radios come with the functionality built in. If you need a PDA or two-way radio, consider one of these hybrids.

• Weather resistance: Like all electronics, you'll want to keep your GPS device out of the water and try not to drop it. Look for a GPS device with a rugged design and weather-resistant features if you plan to use it outdoors.

Accessorise Your GPS Device

Accessorise Your GPS Device

Get the most out of your GPS device with these add-ons:

• GPS software: Download detailed maps, topographic data, and points of interest to your GPS device.

• GPS holders: Stabilise your handheld GPS device on your dashboard or laptop.

• GPS antennas: Amplify your GPS signal and make it more effective. Read item listings for details about device compatibility and email the seller by clicking "Ask seller a question” under the seller's profile if you have any questions.

• GPS chargers & cables: Equip yourself with battery chargers and cables to keep your device powered.

• Bluetooth: Short-range wireless networking helps your GPS device communicate with your Bluetooth-enabled computer, PDA, or cell phone from up to 9 metres away.

• Memory cards: Expand the capacity of your GPS device with an extra memory card.

• Adapters: A cigarette lighter adapter provides a convenient source of power on the road.
