What is GPS?

GPS stands for The Global Positioning System. This is a network of 24 satellites that providing positioning, navigation, and timing services to people and objects on the Earth.

These 24 satellites are broken up into six groups of four and orbit around the earth twice a day. They send signals down to GPS receivers and can be used to determine the latitude, longitude, and altitude of the receiver. By triangulating the information from three satellites, a GPS device can tell a position to within a few feet. Because signals are received from satellites, buildings and tall trees can sometimes interfere with GPS reception, but recent advances in technology have greatly improved the reception of most GPS devices.

Why Do People Use GPS?

GPS has become widely used in land, marine and air applications. Mainly because its signal can be picked up anywhere in the world, even below water, there have been numerous innovations in the technology.

Most of the common uses of GPS come from land applications. Many people have discovered how helpful a GPS system can be in their cars. These systems not only provide maps and turn-by-turn directions, but now often come with MP3 players, hands-free cellular calling, and other handy features. Athletes have also found that GPS devices can assist them in their sports. Bikers, hikers and runners use GPS to monitor their progress and to keep from getting lost. GPS has proved essential to many boaters and fishermen as well. Chart plotters and sounders are helping captains to navigate through shallow waters, and GPS fishfinders make the weekend angler sure to get a bite. This technology has even helped parents with the dreaded sixteenth birthday. Special GPS systems allow parents to monitor the driving speed and location of their children to ensure that they are following the house rules. Finally, GPS devices have made companies large and small more efficient by allowing managers to track assets, monitor employees on the road, and create custom routes that can be downloaded onto individual devices in vehicles.

What Should I Look for in a GPS Device?

Screen Size –GPS devices come in many sizes, and you will need to look for one that matches your needs. For an automotive GPS, a unit with a larger screen will be easier to operate and see while driving. Wide screens rather than standard screens will also improve visibility and allow you to see more of the map at a glance. RV and truck drivers may want to invest in an oversized screen then can be up to eight inches. On the other hand, if you want to use your GPS for hiking or running, a more compact device with a smaller screen is better for you.

Visibility in Sunlight – The display screen should be easy to read in a range of lighting conditions. Many units will come with an illuminated screen for settings with less light. The best bet for many lighting conditions may be a screen that automatically adjusts according to the ambient light. Devices with black and white screens will almost always have the best visibility in direct sunlight.

Size - If you plan to carry the device with you, because you are hiking or just slipping it into your bag to help navigate foreign streets, look for a smaller and lighter device. It is easy to compare weights and sizes of GPS models by looking at the manufacturer’s specifications.

Mounting – For cars, most GPS devices include a mounting bracket and a suction cup for your windshield or dash. Another option available with many units is a mount that fits onto the air vent or a friction mount that sits on your dash. These are popular in states like California and Minnesota where it is against the law to have anything mounted onto a windshield. For motorcycles, look for special mounts that attach on to the console based on the model of bike. For boats, many GPS devices are bolted onto console, but suction cups for mounting are available as well. Make sure to check whether the GPS that you are considering comes with a removable or permanent mount, and check out reviews to see how easy removable mounts are to attach and remove.

Battery Life – Batteries on GPS devices are either replaceable or rechargeable. Most automotive units will come with rechargeable lithium-ion batteries that can be recharged by plugging your GPS into your cigarette lighter, computer, or wall socket. Many handheld GPS devices, however, will have replaceable AA batteries. You can check the manufacturer’s estimate of battery life, but be aware that you may get as little as fifty percent of that advertised time in everyday use. A good rule of thumb is to have an extra battery or power source if you are taking a long trip.

Extra Data Support – Many devices will provide you with real-time traffic, weather, and gas price updates and suggest alternate routes in congested areas. These features are an option on many devices and can be very helpful, but require a subscription. On average, you can expect to pay a subscription fee of around $60 for these features. If this is something that is important to you, however, check to see if the device comes with the proper antennas and receivers already built-in, or if you will need to buy an external antenna.

Ease of Use – GPS devices vary widely in user interface. Look for a GPS that has the features that are most convenient for you. For example, in some products you can choose between a QWERTY or alphabetical keyboard. You should also look to see whether you will interface with the GPS by pressing buttons on the body, or using menu screens. Keep in mind that having lots of features does not necessarily mean that a GPS device is hard or complicated to use. Read reviews to find out if the system is intuitive to the user, or requires lots of time navigating through screens to find the right control.

Spoken Street Names – A variety of voice options are available on most GPS devices. An increasing number of devices are coming equipped with “text-to-speech” technology. “Text-to-speech” enables the GPS unit to speak specific street names rather than vague turn directions. For example, the unit will say, “Turn right on Main Street” rather than “Turn right in 30 feet.” This feature proves to be very helpful when streets are spaced close together and you need to keep your eyes on the road ahead. You may also want to look for a device where you can choose the language, accent and gender of the GPS voice.

Availability of Maps/Updates – The maps that are displayed on the GPS device may be either 2-D or 3-D. Look at the quality of the maps provided and make sure that there is update feature so that your maps are always current. Some GPS devices require you to purchase data cards that contain updated map information. Consider what is important to you in getting the most updated maps available, and the price that different options will cost. You should also look at the maps that come standard with your GPS device. Most automotive GPS devices come with the USA and Canada standard, but some also include Mexico, Puerto Rico, Europe, or other places. You may want to buy a slightly more expensive GPS system that has the maps that you need already included, than have to buy extra map information after-market.

Other Fun Extras – GPS devices that contain MP3, video, photo and FM transmitter capabilities are now available. Consider what you plan to use your GPS for when looking at these features. An FM transmitter is great for playing MP3s you’re your car’s stereo system or using Bluetooth technology to make hands-free cellular calls. If you are taking a family trip or a long drive, consider a device that allows you to plug in an external DVD player. Look for a device that offers a combination that works for you!

Types of GPS Units

"On the Road"

For Cars

Portable automotive GPS units are GPS devices that can be manually added or removed from your vehicle. They are usually attached to either the windshield or the dashboard of your car. These units are very practical and can be used in multiple cars or used outside a car to navigate through unfamiliar streets on foot. Portable GPS devices navigate as well as factory option GPS devices found in luxury vehicles, but offer greater flexibility and may contain more features.

For Motorcycles

Though you can use a regular automotive GPS with a special mount for a motorcycle, motorcycles really require a different kind of GPS device than cars and trucks in order to be used easily. Luckily, there are several units available to help you find your way on your next bike ride. These GPS systems provide the convenient features of most automotive GPS devices, but are designed especially for your motorcycle. Many motorcycle-specific systems come with a built-in headset for helmets to make communicating with your machine easier while riding. The interfaces on these GPS systems also typically come with larger buttons to make it easier for riders wearing gloves to use them.

For RVs

If you like to go RVing, then you’ll love having a GPS along for the ride. Though you can use any regular automotive GPS unit in your RV, there are some devices that are especially good for RVs. A larger screen is one of the first indications that you’ve found a great RVing GPS. Screens are available to over 7” which is huge compared to most regular GPS systems for cars. Other features to look for include remotes, since it can be difficult to reach the screen in an RV, and video input jacks. Video input will allow you to view your back-up camera on the GPS screen, or even to plug in an external DVD player for a fun night in.

Vehicle Tracking

A more recent outgrowth of GPS technology has been tracking systems. Vehicle tracking allows companies to monitor employees while in company vehicles, and allows parents to keep track of their kids’ driving habits. Many regular automotive GPS systems log various details of a trip, such as highest speed, average speed, and number of stops and stop times. However, these logs can be deleted by someone from the unit itself. With a dedicated vehicle tracking system, updates are e-mailed to the control user with vital statistics. These service do require a monthly fee, however. Whether you are checking on your business assets or making sure that your kids are safe on the road, a vehicle tracking system can give you peace of mind.

"On the Water"

Chart Plotters

GPS chart plotters are an essential piece of equipment for many boaters. These devices are used for marine navigation. They combine GPS information with an electronic navigational chart of the water. Chart plotters allow users to gauge the position, speed and heading of their boats, along with other specific information. Basic chart plotters will simply help you find your way on the water, while more sophisticated chart plotters come equipped with sounders, fish finders and other features that help users avoid underwater obstacles and get the most out of their boating experience. To determine what kind of chart plotter you need, consider your activities in your boat. If you do not fish or travel extensively, then a basic chart plotter may be fine for your needs. If you fish or navigate through shallow waters, however, you may want to invest in a chart plotter with a fish finder and sounder built in.

Some Chart Plotters that you might like:

Sounders

A sounder is a key piece of boating equipment that sends a signal from the bottom of your boat to the bottom of the body of water and receives the signal that bounces back. Many sounders are available packaged with chart plotters or fish finders and provide integrated features to their users. This information allows you to see the depth of the water, as well as fish, wreckage, barriers, and other obstacles. underneath your boat. Don’t go into unfamiliar waters without one!

Some sounders that you might like:

Fish Finders

Fish finders allow anglers to identify structures and fish below and around the boat. These units make fishing easier and will help you catch more fish than ever before! There are many fish finders available that offer different capabilities. Look for pixel size and the type of radar used to find the one that is best for you.

"Outdoors"

For Hikers

Whether you are an experienced outdoorsman or just a weekend hiker, there is a GPS unit to help you find your way. Handheld GPS devices have smaller screens and usually carry a longer battery life. Look for a size and weight that will work for you on your treks. You also check what kind of map features are available, along with extras like a compass. Some hiking GPS devices come with a system of trail maps in place, but you may need to purchase extra maps before you head out. There are also GPS devices available to track your route, share interesting points, and even take pictures along the way.

For Hunters

Companies have developed GPS systems specifically for hunting. These units generally have many of the same features as a regular handheld GPS, but are waterproof and often designed to be easily manipulated by one hand. A hunting GPS device will not only track your route, but allow you to save waypoints so that you never forget that perfect hunting spot. There are even GPS systems with two-way radios built in so that you can easily communicate with the rest of your hunting party. Look for a device with a screen that you can read easily and with easy to use buttons. You also might want to look for a device that can measure distances in yards rather than miles for an easier conversion to shooting distances. Finally, if you hunt with dogs, you may also want to invest in a dog-tracking system. These devices use GPS to constantly monitor your dog while you’re out hunting to allow you to focus on the game. When you take a hunting GPS out with you, it will not only help you bag that ten-pointer, but help you find your way back to the car as well.

For Cyclists and Runners

GPS devices aren’t just about finding your way; with the advent of fitness GPS they can also help you train. GPS systems designed especially for cycling and running allow athletes and couch potatoes alike to monitor their heart rates, record lap times, and intensify training, along with making sure that you can get back home. Look for a device that accomplishes the functions that you are looking for. Certain products are designed much more for tracking fitness levels than navigation, so if you plan to take your GPS into unfamiliar territory, you may want more detailed maps and features. Also check the form factor. Especially for runners, a small device is often better. Some systems attach to your upper arm, while others are worn on the wrist and even attach to your shoes! Choose one that will be comfortable for you.

For Golfers

If you the links, or know someone who does, then a golfing GPS unit is the one for you. These devices will help you find the fairways with every stroke. By measuring distance to various features on the course, like the front or back of the green, bunkers, and water hazards, you will always know which club to use. Some golfing GPS systems will even track your own yardage. When looking for a golfing GPS unit, check out size. Many systems are made-over hiking devices, so they can be rather hefty. However, some newer and much smaller units are coming out that will fit easily in a pocket. You should also check to see if the unit will map any course, or if you will have to download course data from a website in order to use it. Whatever your preference, having a golfing GPS on the links will not only help your handicap, but make you the coolest duffer on the course.
