GPS stands for global positioning system, a system that has been established and is managed by the Department of Defense. The GPS system utilizes satellites that have been put into orbit that help people determine their exact positioning on the plane t- whether it be for the purposes of navigation, for the purposes of military use, or any type of enterprise that requires an exact global positioning by latitude, longitude and altitude. In fact, sometimes GPS systems are installed in vehicles, and some are installed in fishing boats. Finally, some GPS systems are fixed into position, while some are portable.

GPS systems can also be purchased for motorcycles, and hikers sometimes use such systems to determine where they are while walking. Cyclists should not be left out of the mix, and runners, joggers, and skiers use navigation systems to prevent themselves from becoming lost in an unfamiliar area. Some PDAs – personal digital assistants – are equipped with built in navigation devices, while some Palm devices also include such systems.

Navigation systems are sold with a variety of features and what kind of features you should look for is solely dependent on two factors – price and need. The most basic of navigation systems will provide you with a route from one waypoint to another waypoint or to multiple waypoints, depending on your destination and trip plan. A benefit of such navigation systems is that they not only serve as a guide to your preplanned destination, they also serve as guide back to where you started. Any route you plan in a navigation system is completely reversible thanks to the innovative design of such systems.

Alternatively, you may pay more money for a navigation system that has voice capabilities. You can purchase a navigation system that will guide you to your destination vocally and while speaking to you it will offer up a turn-by-turn dictation of your journey. Conversely, those individuals that spend the majority of their time travelling – like a delivery man may find that they prefer a navigation system that they can preplan many destinations at one time and then move from one set of directions to another. Thus, such individuals require a uniquely designed navigation system -one that possesses multi destination capabilities. Finally, there are different navigation systems for boats, motorcycles, cars, and joggers so you will need to be sure to purchase the product you require for the use for which you intend it.

Navigation systems can be easily ordered from online distributors. If you are interested in purchasing a navigation system you may want to read the myriad reviews offered pertaining to such products before you make your purchase. In doing so, you will have a better idea of the various brands available and what other people recommend. Also, you will find complete reviews that will allow you to engage in comparative shopping – this way you know you will be able to find the best navigation system to meet your needs at a price that suits your budget.

So you’ve been trying to find a new way to navigate through the world and you heard about these devices that can create accurate maps and even give you navigational instructions to and from locations right from your car. These systems definitely do exist and are called GPS (global positioning) systems. But of course, before you go out and snatch the first one that you see, you need to learn about these clever little devices to determine which one would be best for you. So in this article, we will do the work for you to help you choose the best GPS systems on the market.

Learning About GPS Systems

If you’re still unfamiliar with these systems, let’s take a look back at the movie Enemy of the State. If you remember, there was a scene in the movie where the character played by Will Smith was being tracked by a device his enemies had placed in a bag that he grabbed. By keeping this device with him unknowingly, he allowed the chasers to keep track of his every move on a screen they were watching from another location. At the time, the device seemed very high tech and new age, but now many people take advantage of them in their own homes and cars.

Modern day systems are capable of working in a very similar way as the device in the movie. You can plant a tracking device in your vehicle that allows you to know every move your car makes if your child drives it – or if it is stolen – by watching its activity from a screen in your house, or even on the Internet from anywhere in the world. In addition, these systems can give you driving instructions via a satellite map to a new restaurant in your area, or give you voice-navigation instructions to a restaurant in a new city. However, you have to decide which are among the best GPS systems, not just from reputation on the market, but also according to what will work best for your family. So let’s help you decide what you want.

Decide What You’re Looking For

Some of the decision-making process falls in the laps of the companies selling you their product. But I believe firmly that one way to help you determine which are the best GPS systems on the market is to decide which ones are best for you – and you make this decision by choosing the features you most need.

There are four main categories of systems out there to choose from, however most companies combine at least two or more features into one device for versatility. To clearly learn about the differences though, we’ll view them separately.

Mapping – There are tons of mapping devices that fall under the category of best GPS systems. This is because more people are usually interested in mapping features, which means companies work harder to make sure this feature is especially accurate and reliable. However, do understand that there is a difference between a device with mapping features and a mapping system. The mapping system is different because it is used to collect data for field work such as farming, timbering, and wetlands/marsh work. Instead, you may want to pursue a system with a mapping feature for directions only, because you could find you’ve bought a device with a lot of “stuff” you just don’t need.

Surveying – Surveying devices can be similar to those for mapping in that they can be pretty complex beasts for the everyday person simply trying to accomplish a few minor tasks. Models that focus primarily on this feature are also used more so for professional surveyors in the field who are looking to collect data on property and land. While you can find these devices among the others available, for everyday navigational purposes, these would probably be too advanced for your needs.

Tracking – These systems can come in the more professional version, but many everyday people are finding them to come in handy when they want to keep track of their children, and keep criminals away. These models can come in a variety of forms ranging from a small device put in a car to track its whereabouts at all times, to a cell phone or watch you can give to your child that can be viewed from a remote location.

Navigating – Many people would say the best GPS systems come as standard navigating devices because they are used to help them navigate through unfamiliar territories with simple and convenient voice turn-by-turn instructions. Of course, as mentioned with the above options, you are likely to have more than one feature in one, but the main idea is to make sure you are getting the features you want – and not a lot of unusable features – for your money.

Now What Do I Choose?

Now that you’ve learned about the differences between the systems, let’s look at a few brands with great reputations for being simple to use with a lot of great features:

Garmin – If price is an issue to you, you may want to turn away from this often expensive, yet always reliable company with a reputation for selling the best GPS systems in the world. Most of their products range from $350 – $750, but you’ll always get plenty for your money, including wide screens, long battery life (if portable), extensive mapping and directory options, accurate navigation, and even MP3 and Bluetooth features.

Magellan – Another company known for selling some of the best GPS systems on the market, Magellan offers a wide variety of products for mapping directions and accurate navigational instruction.

TomTom – This company ranks fairly high as well for its features and offers standard options as well as a Map Sharing tool that gives very accurate and up-to-date information on roads around the country.

Learning which companies offer the best GPS systems in the industry takes time and effort on your part. Of course, this means you’ll need to continue your research beyond the Internet and visit stores with representatives who can show you in person what each one offers. But after doing your research, and determining what you want in a system, you’ll be sure to find one of the best GPS systems on the market that best suits your needs.

On of the most difficult parts of flying is figuring out at what location you are at and then of course the solution to get to where you need to be. In the earlier days the pilots had to rely completely on the compass bearings that were provided to them. The landmarks were also of great help to them and sometimes maps which would help in locating the destination. In bad weather the pilots would be very clueless of where they were going and would sometimes get lost. The weather can be quite a calamity for pilots especially in the older days.

The Aviation GPS systems have been of great help and are definitely keeping the whole journey safe. The pilot will never leave the ground unless he has put on the GPS system. The The global positioning system does not depend upon the weather conditions or maps that are made. The signals that are beamed from geostationary satellites allow GPS systems to locate themselves anywhere in the world. The global positioning systems are used by the military and are compulsory in cars so this proves how essential the GPS systems are and how much they are helping people in their activities.

Getting lost in the clouds is definitely very dangerous for the pilots as they will have no idea of their location. There are many places which the pilot might not be familiar with and that is a completely dangerous. There are a number of other natural calamities that could take place like a storm which can sometimes blind the pilot. The pilots could be very well experienced but it will be very difficult for them or next to impossible to fly without a GPS system. The GPS is like the pilots best friend when in the air. The GPS helps the pilot to navigate which is basically a very important component of being a pilot.

The GPS systems are definitely the guide lines to a pilot even a veteran pilot will agree to that note. Pilots do not fly without the GPS systems anymore. The aviation systems are definitely going to get better in the coming years and there will be advanced equipments that will be essential to use.

There are different kinds of GPS systems that are available so if you want to get the right one then you need to do research on the internet and you will definitely get what you want.

We have a serious problem brewing with GPS navigation systems for automobiles and even motorcycles. There are however problems with this devise as a high tech toy are more serious than you might think. Ask anyone in a metro area who has bought a new car with one of those cool GPS upgrades for their SUV or new sports car. We have had our customers complain (customers of the carwash business, which is my profession). Oh they love the gadget, but they are under whelmed by the lack of data and streets, which are not listed. You see we have been seeing incredible suburban growth in many cities. Places near large DMA metros are a problem out in the middle class suburbs. In many areas such as outside Chicago, Los Angeles, San Diego, Phoenix, Las Vegas, Seattle, Portland, Denver, Dallas, Houston, Austin, San Antonio, Nashville, Kansas City, Minneapolis, Columbus, Cleveland, Baltimore, Jacksonville, Tampa Bay, Miami, Orlando, Atlanta, DC Subs, etc. And in NJ, NC, NV, OH lots of other fast growing growth pockets.

When GPS devises for cars first hit the scenes at the CES and SEMA shows in 1996, they became increasingly more popular, powerful and better data. But like VHS and Beta, Apple and IBM, competition became increasingly greater causing much consolidation in the industry along with patent fights. Much of the technology was former Defense Contractors peddling their wares through subsidiary consumer level companies. But the tight market remained due to the costs. Meanwhile companies like DeLorme and others tried to flood the market with low priced GPS units, which made things even more competitive. And the bugs were not fully out of the system yet. Someday all cars will drive themselves and people can watch TV, do video conferencing and use their transportation as a portable office or entertainment system while they are being driven to the location they have punched into their computer. Some things will have to occur before this is a reality of course. But eventually your dexterity skills to actually pilot a car will be worthless and un-needed.

First the satellites will need to be laser aligned and use multiple satellites to get absolute locations of ground items and vehicles. The cars will need to have additional anti collision devises made up of networked sonar and optic flow sensors. All of which are now available and the technology is getting better and better. Many military applications today will be civilian tomorrow. Just like Radar, Microwave ovens, Nuclear Energy, Cellular Phones, Satellite Communication and Jet Aircraft in Commercial Aviation. The flow of transportation will be brought to the next generation to serve man better.

For the time being the incremental changes in these technologies has hit a slight road block even though Honda, GM, Ford, Mercedes, Daimler Chrysler and Toyota have invested billions in anti-collision and safety devices which they will add comfort and desirable options which they can sell to customers as upgrades. Smart Car Technologies can add Thousands of Dollars to the price of a car and consumers are glad to pay for them. A factory GPS system with display can cost up to $6,000.00 and they sell a lot of them on the higher end cars. It is a high profit item upgrade, although there are some, which only cost $1000. And if you wish to compare these, some are very incredible with many features;

There are many companies, which sell after market computer assist items. These companies are doing quite well and the systems work great. The big issue is just because you have a super duper incredible GPS system, does not mean the street you are looking for is even on the map yet. In other words it is like using an old map. If you are a studier of maps like I happen to be, you will see the problem with older maps. Even some companies keep printing old map data year after year without adding in new on ramps, city streets, infrastructure freeway improvements and ring-roads, it is aggravating for those from out of town. Even more aggravating looking for an address or street in a new housing tract, which you can see but the devise insists, does not exist? Then there are problems in areas like Cape Coral, FL and Tehachapi, CA or El Paso, TX and Knoxville, TN where the roads have been scraped and ready to put in or put in but do not connect or have nothing there yet. Of course it is very aggravating to see a road and try to go down it and find it is a dirt road that connects to nothing yet or an entire sub-division that does not exist? Is it a Mirage? If so where is the white Tiger Show?

Jack Dangermond of ESRI had set up entire networks of software makers who developed data for their awesome software products for GPS and GIS needs. Used by government, military, utility companies, transportation companies, private companies with GPS units to sell to the public, First Responders and school districts for buses. After the Dot Com crash those software companies were among some of the survivors, but had significantly cut costs. Thus without the proper data the GPS systems bought by the upper, upper-middle and middle class for their cars were not always good enough to support the price point for the newest technology. This is especially upsetting since the upper, upper-middle and middle class citizens who pay the most taxes live in the suburbs for the most part. The chances of a middle class American; who bought a home during the 3 years last housing boom; not being able to find their house or street on their new GPS devise is a higher probability then them actually finding it. We interviewed one man who bought a new Nissan Sports car.

Who lives in a newer developed area in the higher end Las Vegas, Clark County Suburbs, which only had the main streets on his GPS and had huge blank spots on his device? Some GPS devices allow the user to choose a satellite vendor and data vendor and software, but many of the Factory units do not. People think they are getting something really good and then find they cannot use it to navigate, which would really piss you off considering you may have paid as much as $6,000 for the unit. Even more dangerous is the information we learned from an EMT ambulance driver in Dallas area who told us of looking for streets for 15-20 minutes after battling through suburban gridlock to get to where they thought it might be. 3G cell phone technology may assist for those using cell phones to call in data to the dispatches. For all the training we are doing across this nation for first responders and on-going education of police, fire, Hazmat, etc. it appears that we have forgotten the problems of the system. Any time you build a system to serve humankind you must make it simple and make it work, that should be the first, the very first priority, then you can fix all the other issues.

With that said we interviewed a lady recently one evening who had a hell of a long day working for the Metro Police Departments Central Nervous System. The communications center and dispatch is to what we are referring. Although she was unaware of the problem at the center for bad data or missing data in the system, she could not say how they were able to get the information. Luckily serving a metro area they are probably connected to the planning departments computer, which they should be. And if the police department has the new data and no problem in this case, why have the software vendors not been able to access the data? It is a safety issue if someone with a GPS system pulls out a map and tries to read it while driving in an area they are not familiar with. It is guaranteed that in the history of the automobile in this country more people have been in serious traffic accidents from trying to read maps, than talking on cell phones, although cell phones no doubt a contributing factor in many lesser accidents will eventually pass this figure. Where the streets are, well frankly I cannot understand the need to keep this a secret unless it is the layout of Area 51, Prison, Power plant, Pentagon grounds, Military Bases, etc. If the emergency first responders divisions and contractors would share the data, there might be less accidents and they maybe able to get some assistance from the public being the eyes and ears

http://www.lancewinslow.org/nmwp.shtml

and also perhaps they could in fact use the idea of Smart Virtual Mobile Communities or FlashMob scenarios since budgets are strapped as the National Security “Red-Orange-Yellow-High-Risk-Danger-Days” come with high frequency, more police and first responders are on duty and that costs money. Without significant inflows the coverage of the Grid of a city is in jeopardy of slower response times. Fast response times are the easiest way to keep the peace, everyone, which gets away can cause problems another day and of course in case of International Terrorist Attacks.

It is essential to have the data for these devises and everyone is better served when communication flows. GPS units provide that and the data should be readily available and probably it is best to have the cities using the same formats as first responders and the same data can be used for utilities, consumers, military and even census data or academia studying urban sprawl and growth rates to have infrastructures ready during expansion. Things like water and energy, which has obviously been a major focus here.

There needs to be a nationwide coordinated effort to see that such data is filtered into the private sector, because as it stand the companies have been hammered in the industry and cannot perform the services to bring this stuff to market. Communication is important for government and citizen a like, increased efficiencies in business will save the government money and provide additional tax base and funds on the income of such businesses utilizing such data, as well as save money and time for all the government services discussed above. If we want a screaming economy we ought to be thinking how we can streamline and accelerate the flow of information to increase efficiencies and allow a small portion of the gain from the expanded pie to continue the growth. In other words, we make it easier for the Florist to deliver, the school buses to pick up more kids per hour and the soccer mom to take more kids to practice and still have time left to shop all of which serves man. The digital GIS divide is as important for our economy as the Digital Internet Divide. Kids in sports do less drugs, become more competitive, have higher work ethics and soccer moms can help keep the retail economy going. Every time you ease the flow, more things are possible. The exponential increase in American productivity is needed to offset the time lost in traffic and congestion. GIS-GPS systems can help in any emergency or simply driving around town getting things done to check off one’s list for the day.

GPS, abbreviation for Global Positioning System is the most accurate and sophisticated navigational system in the world. This system is used to track and determine one location on earth. This system was initially designed in 1960s by the US DOD (Department of Defense). Since then it has undergone various evolutionary changes in the past three decades. Many satellites were designed and launched during that period and finally a complete set of 24 satellites was integrated to form NAVSTAR in 1993. These two dozen satellites orbit the earth to provide navigational data to military personals as well as civilians. The result is what you have a user end satellite navigational device to guide you safely to your destination. The maintenance of these satellites itself costs the US government around $800 million every year.

Initially, people used paper maps and compasses to navigate or trail through unfamiliar territory. Now, with the advent of personal navigational systems, they have all taken a back-seat. This is because; personal Sat Nav is portable and light weight and includes the latest maps. GPS enabled cars and vehicles are safer as compared to the ones without it. These compact units determine and display your exact position, speed and direction in which you are heading. It can also tell you the correct time at which you will reach your destination. As the GPS devices come with preloaded maps, they can be used to navigate anywhere across the globe.

GPS System works on a complex mechanism consisting of satellites, monitoring stations and GPS receivers. These are the three major parts of a GPS application.
