Portable GPS Units Get You Back On Track

Many popular sports are popular because they have an element of danger because they are set out in a place where you can get lost.  With boating, you can potentially get lost in the sea.  With rock climbing or mountaineering, you can get lost very easily on a mountainside or in the wilderness.  You can also get lost in nature and lost in direction while hiking, camping, biking, snowmobiling, skydiving, four wheel driving or (if you’re like me) shopping.  Portable GPS units can get you back on track and back to safer ground.

Science Fiction Now Science Fact

Many science fiction books and television shows of the sixties and seventies made use of a fantastic gizmo called a tracking device.  No matter how desperately lost the hero or heroine was, their faithful crew or comrades could find them (or loose them again) by following an electronic trail put off by the tracking device the protagonist was wearing.  As long as the protagonist wore the tracking device (or didn’t get into an “ion storm”), the cavalry was always on its way.

This tracking device has manifested into the portable GPS units of today.  But both fictitious and factual devices rely somehow on the stars.  In early science fiction, the tracking devices transmitted to a spaceship.

In real life, an orbiting satellite transmits to the portable GPS units, which in turn can transmit to cell phones, websites or emergency services.  But I don’t think any science fiction author or scriptwriter got any money from portable GPS devices, just technology companies.

Two Kinds

There are two kinds of portable GPS units – those that work like electronic maps, and those that let others track you down when you are lost.  Both kinds have their advantages and disadvantages.  See what kind of lifestyle you live to help you choose.  GPS devices that work like electronic maps are usually the less expensive and more easily found variety.  They are common in new cars, the newest cell phones and in PDAs (Personal Data Assistants).

The personal tracker kind of portable GPS units are recommended for those going into potentially dangerous situations.  It is also recommended for children and pets that can wear a collar.  If you enjoy somewhat risky sports, hobbies or jobs that require any time away from a peaceful civilization, then portable GPS units are not just a cool toy, but are as necessary as a first aid kit.

Choosing A GPS Device

If you are looking for a global positioning device, there are many GPS devices from which you can choose.  In fact, there are so many global positioning devices to choose from, that it can be confusing to choose one if you are new to GPS devices.  You can choose a GPS device to match the activity for which you will be using the global positioning system.

Four Main Types Of Receivers

There are four main types of GPS devices and in each of these categories; you have a variety of options for your final choice.  The four types of devices are the PDA/GPS hybrid, the car navigation system, the marine system and the portable unit for outdoor activities.  You may need a portable GPS device or a PDA/GPS device, if you want to use the global navigation system away from your car.

Different Functions For The Receivers

When you do know what type of GPS device that you want, you will then have to choose from the different functions that the devices have to offer to you.  If you are going fishing, you can choose to get the navigations capability with the fish finder tool for instance.  Another consideration is if you are going to be using your device while hunting or hiking, you will need a device that is lightweight, waterproof and has a lighted screen for viewing in the dark.  If you are travelling in your car, you will probably want a device that can speak the driving instructions to you, while you are driving.

Choosing The Features

After you have decided on the type of GPS device that you want and you are sure that it is the right one for you, you must then decide on the features that you want with your device.  You will probably want to steer away from the GPS device with all the bells and whistles because at this point, you will probably not need all these features.  At the same time, you do not want to get the sparsest GPS device out there because you will want to have some fun with this technology.

No matter what the job or activity there is a GPS device that is suitable to do the job.  It does not matter whether you are walking and using your PDA to find a restaurant or you are in your car looking for the same restaurant, the right global positioning device will help you to find your way.

GPS Comparison For Campers And Mountain Rescue

GPS technology has the potential to become of the most miraculous tools for saving lives.  At the moment, most GPS devices work great only if they are out in clear settings.  The GPS satellite orbiting the planet sends down low level radio transmissions to be picked up by your GPS handheld device.  However, these transmissions often can’t go through rocks, buildings or trees.  If you are trying to find your way through the woods in deep winter, your GPS might be useless.  So, here’s a summary of a GPS comparison made by the United States Department of Agriculture Forest Service.

Test Parameters

These GPS comparison tests were made in the summer of 2000, about a generation of GPS devices ago.  Most of these models or updated versions are available.  Three test “courses” were used in three National Forests and training centers in Montana, California and Idaho.  The goal was to work under very thick forests in the height of their foliage.  There were about five volunteers in the GPS comparison study.

Devices Compared

The GPS comparison was between:

Rockwell PLGR-96
Trimble Pro XR
Trimble GeoExplorer 3
Magellan Map 410
Garmin GPS III

Summary

The GPS comparison also included how accurate the GPS devices data was to where they actually were.  They found it was very hard to get an accurate reading when directly under a tree.  They still needed to try to get a clear patch of sky in order to get an accurate reading.  Not only that, they needed to see a recognizable constellation, like the Big Dipper.  One of the advantages of a forest is that stars are much more brilliant because artificial lighting isn’t covering them up.

In the end, the GPS comparison did not recommend the Rockwell and the Trimble Geo 3.  The Rockwell is professional device of $10,000 and well out of the reach of any camper or mountain rescue unit.  All of the other units of handheld GPS devices were recommended.  But the costs of GPS devices have lowered considerably since the 2000 GPS comparison tests.

They also recommended purchasing additional antennas that can be attached to most GPS units to amplify the reception of the GPS satellite radio signal.  Some GPS units now come with antennas that can extend out like a transistor radio antenna.  These antennas often fit cellular phones.  The GPS comparison test showed that the latest technology and latest models were more cost efficient in finding out where you were in the forest.

Some Things Worth Knowing About Bluetooth GPS

It seems that in more than a century that has seen the evolution of electronic devices come a long way from the early mainframe computers to the present handheld devices that a lot of water has flown under the bridge. And, during all this time the highly convenient wireless technologies have emerged and thrown up many interesting things including Bluetooth GPS that has done away once and for all with all those mountainous wires and cables that were needed to connect devices together. And, now GPS has done away with maps and made them available electronically and without the need for paper maps.

Changed Our Lives Forever

With Bluetooth and GPS technologies coming together, it has changed our lives for the better and Bluetooth GPS is a meeting of the best of these two worlds in which interactive devices allow you to remain connected while on the go, and maps as well as positions and finding resources has never been so simple. Along with outstanding storage and compactness of size, Bluetooth GPS is really a revolution in the making.

Gone are the days when you needed to connect your GPS unit with a PC using wires, and today the wireless technology has made Bluetooth ideal for networking in small areas. Bluetooth GPS can be used in different ways and once connected to the computer through a network notable for the absence of wires; you don’t even need to get involved personally. Gone too is the need of juggling with connectors and all that you need is to be within range of the Bluetooth network and you will get a number of benefits including sending data to your GPS.

Thus, it should not surprise you to know that today there are many new models of Bluetooth GPS and the rate of obsolescence is pretty high, which can be attributed to its growing popularity. Today, you will find different Bluetooth GPS units available for different price ranges and different features as well. However, before selecting a particular Bluetooth GPS system, makes sure that you know about all of its features and buy according to what suits your needs the best rather than going by sales pitches. The best place to source Bluetooth GPS is of course, the website of the manufacturers where you get all of the latest on offer and also complete details as well. In addition, there are sure to be user reviews though your main concern should be how much of an advantage will you get from your Bluetooth GPS.

Best GPS Review Comes From Actual Product Users

When looking for a global positioning unit or service you should always first review the many different makes and models on the market before making a purchase. Some of the best GPS review information can be found from user of the equipment as they will usually present a more honest opinion of the equipment when it is used in a real life scenario. While manufacturers’ information can be helpful in learning the different capabilities of a specific unit, its ease of use and how well it works under certain conditions are often found on the best GPS review site.

Whether you are looking for an automotive navigational system or a tracking unit, the best GPS review will be available on independent sites that do not count on the system manufacturers for information. Finding reviews is relatively simple, especially with the many sites on the internet, but read the information carefully to separate the real opinion from the advertising hype.

No one lost in the woods has ever been found by a marketing plan and knowing that the unit you are purchasing has the best GPS review and is recommended by someone who has used it can make you feel better about spending your money.

Compare Intended Use Against Reviewer Statements

When looking for the best GPS review on a certain type of product, consider the intended use of the device. If you are not the avid outdoor type who will spend a lot of time hiking unfamiliar trails, an altimeter may not be necessary on your unit. A barometer may also not be useful if most of your time is spent indoors on in a vehicle. A unit that claims to offer the best type of these features, may not be of particular interest to you.

Carefully consider what the unit is to be used for and then look for units containing the best GPS review concerning those features. Many comparison sites offer the varying features and how they match up to brands and models, usually in the form of a chart. By finding the features that you will utilize the most, you can then find the individual unit that offers the best GPS review for those features and make an informed decision.

Manufacturers will tell what their units can do, but the best GPS review will tell you how easy they can perform each function as well as how difficult certain things may be to complete. Loading maps and isolating specific locations may be easier on one type than on another and the best GPS review will help you know which is which.

Since the government launch its GPS satellites, locating just about anything in the world has become considerably easier. From finding stolen cars and locating lost pets to keep airplane and cruises ships on track, GPS has made the world of navigation simple. And while the signal emanating from the satellites is free, what is done with that signal will cost, depending on that it is the user hopes to accomplish.

Initially established to help the government locate numerous types of assets around the globe, GPS is now used in locator services as well as navigational services available in many private vehicles. Using this service costs the end user, but the ability to locate a stolen vehicle and even find missing persons by using their GPS-enabled cell phones provides many valuable services to the population.

A handheld GPS unit can help people figure out exactly where on the planet they are located. Using this information can help them find their way to another known location, which is essentially how navigation services work. Although getting turn-by-turn directions from one place to another is a service provided by a non-government company, using the signals sent from the 36 working satellites equally spaced around the globe.

More Satellite Signals Offer Better Location Services

When personal GPS units became available, there were only about 24 working satellites sending signals from orbit. Depending on the location on the planet, most devices could only receive about four or six signals, given the satellite’s given location and the need for line-of-sight reception of its signal.

As the number of satellites increased, so did the number of available signals and today it is not unusual to have a personal GPS device able to receive signals from up to 18 or 20 different satellites. The more satellite signals a unit picks up, the more accurately an exact location can be configured. For example, receiving four signals can offer a spot withing a few hundred yards of the person’s location. With a GPS unit receiving 20 signals, the location can be pinpointed to within a few inches.

The most common uses for GPS navigation is on aircraft as they find themselves engulfed in clouds or fog and relying on radar to fins them can be questionable. With the use of GPS systems, their exact position in the sky can be pinpointed, enabling traffic controllers as well as other aircraft to avoid a mid-air collision, providing for the public welfare and safety.
