There are a many of GPS Navigation systems available on the market currently. The wide variety of brands and model types make the selection of a perfect navigation system confusing and tough. Companies offer different models at times, and they also come in a broad spectrum of prices. So, it is very important for you to know what factors you should consider before you purchase one. It is wise if you try to get a clear picture in your head of what you want.

Basically, nav. systems function as your directional guide. It helps you get from one place to another. This is accomplished by creating waypoints. Imagine you are strolling in a maze, and in order to return to your point of origin, you need to leave some markers, which will make it easy for you. The waypoints are more or less the same. They are like markers that assist you find your way back, in case you are lost. This is such a very important feature of a navigation system, especially for tough terrain. When you are skiing, this can become extremely helpful. So, first thing you have to check is the nav system capability to provide you waypoints. It will also be fabulous if the model is capable of adding up or storing new mapping points in its memory.

Another thing you should consider is the ability of your GPS to reach rough places. You must take notice that not all devices can pick up strong signals from satellites. If you are planning for an outdoor excursion, this detail is crucial.

When you have a Wide Area Augmentation System (WAAS) enabled nav system it will surely make it delightful for you to enjoy skiing with ease. Wide Area Augmentation Sytem (WAAS) is a satellite system that works in tandem with fixed stations on the ground that gives the GPS receiver signal corrections, thus giving you a pinpoint accurate position than a traditional GPS device reading. In average conditions, it can pinpoint your location five times better than a regular GPS reading. If your device is WAAS-enabled, then it can provide you a position accuracy a few meters.

In addition, from its essential functions, you must also keep in mind the physical characteristics your GPS device offers. Being handy while outdoors is an essential detail. Having a GPS device that is not bulky or heavy will be a plus factor for your excursion. Convenience in using the product is also vital. Display screens can be a factor, as well. I prefer the colored ones, as they are easier to follow than the black and white screens. Battery life plays a vital role also. I don’t think you would like to be in the middle of rugged places without any idea where you might be. Make sure that the unit offers a decent running time for its batteries.

At the top of the leading brands on the market today, I recommend the Garmin eTrex Legend HCx. This GPS provides a high-sensitivity receiver for your GPS device, which allows clearer reception wherever you may be. It is also WAAS-enabled. The Garmin eTrex Legend HCx also has a anti-glare display screen that is readable even in direct sunlight. The eTrex Legend has taken into consideration all of the necessary needs of outdoors enthusiasts and have not missed a thing.

In the late 1950s Sputnik became the first ever satellite to orbit the Earth. Again it was American researchers that quickly realised the theoretical usefulness of the satellite in terms of navigational purposes. They calculated, using the Doppler effect, that the radio frequencies of the approaching and departing satellite could be calculated in order to give an exact positioning of the object. Also because the object was 11,000 miles above the Earth its trajectory could be predicted incredibly accurately. With growing knowledge the US military developed its own satellite navigation system in the 1960s and called it the Transit System. Satellites were put into orbit around the poles, and nuclear submarines carrying the Polaris nuclear deterrent were able to take the signals in order to calculate their position beneath the waves.

The Navstar system had its inception following meetings at the Pentagon in the early 1970s. The idea was to improve on the current imperfect system of GPS by having 24 satellites built, each with four atomic clocks to ensure their complete accuracy in terms of time and position in orbit. The satellites, built by Rockwell International, were launched in a way that at any one time at least four satellites covered any given area on the earth. Each satellite would emit a continuous digital radio signal revealing time and position accurate to a billionth of a second. A receiver on earth was able to receive the satellite data and calculate its position on the planet’s surface.

So it was for the first time that somebody with a relatively simple quartz-powered satellite radio signal receiver could get their position accurately calculated by four satellites working in tandem. Careful monitoring from earth made sure the 24 satellites remained accurate in terms of their atomic clocks and their timings and positioning. This self same technology is the one we use today to power our Garmin, Satmap or Memory Map handheld devices; though born through military innovation and necessity today’s GPS happily can be put to more useful and peaceful means.

Nowadays of course we have the benefit of adventure and handheld GPS packed with handy navigational features. You can find zoom and pan, you’ll find barometers, altimeters, detailed mapping on full colour screen and loads of options to analyse your route before and after your trip. Thanks to rapid advances in science and technology those early innovations have given rise to a fantastic range of GPS available for today’s outdoors enthusiast.

Right, let’s have a chat about the Montana 600 series. You will find three different models within the 600 series, the 600 itself, which I will talk about today, and then the 650 and 650T specifications, with the “T” indicating that the unit comes with preloaded topographical maps, things which you usually have to buy apart. The 600 is the basic model, so that is the one thing I will discuss. You will find the others will not differ too much in spec.

Of course Garmin are one of the biggest players in the world of satellite mapping, and with so much market dominance they have been able to really pour their resources into the Garmin Montana 600 series. They have taken their know-how in the world of car satnav and combined it with the best features of some of the handheld GPS devices to give a really neat combination. You will notice it is a little bit bigger than your normal handheld GPS device. It is because it is designed for use on the dashboard of your car or boat and necessarily the screen needs to be a little bit bigger, at 4 inch diagonal, so that you can see it clearly.

The Montana 600 series is unique in that you can put it in your car and navigate to the waterside, take it out, stick it on the dashboard of your boat, across the lake, get to the other side, take it out and then load up the map so you can go straight up the mountain without getting lost. It’s equally comfortable in any of its three modes of navigation. On the water it will make use of the BlueChart G2 preloaded cards, in the car you can use Navigator NT and Garmin GB Discoverer which give spoken turn by turn directions, and then for other activities such as hiking, camping, fishing and the like you have the normal GB Discoverer range, and the Birdseye Select. If this all sounds a little confusing or if you are not familiar with Garmin and their range of mapping add-ons, as I said please follow the link below where you will find more information Garmin and other GPS devices.

One of the great things about the Montana 600 series is the dashboard and the interface. Big colourful icons make the touchscreen easy-to-use, and you can arrange your dashboard however you like. The home screen has an option to allow you to customise 16 different features including “Address”, “Map”, “Where To?” “Shortcuts” and many more. You can find various screenshots if you follow my links at the bottom of the screen and explore this device a little bit more. Sometimes describing something in words is a little bit tricky so have a look at the pictures to learn more. Suffice to say, with the big screen and excellent resolution this is one of the most user-friendly GPS around.

Okay, there is a whole lot of things I haven’t spoken about on this device, including the battery life, capability for geocaching and points of interest and a whole lot more. I hope you’ll follow my link below and find out a lot more about this and other GPS devices. Really GPS is quite a complicated world, and the best thing to do if you are thinking about buying one is to have a thorough look at what is on offer and compare and contrast. Thanks for reading.

To create a standard for a mobile telephone system that could be used across Europe, in 1982, the European Conference of Postal and Telecommunications Administrations (CEPT) created the Groupe Spcial Mobile (GSM). In 1987, a memorandum of understanding was signed by 13 countries to develop a common cellular telephone system across Europe. Led by Torleiv Maseng, the cellular phone system was created by SINTEF. Also in 1987, the release of mobile phones in Germany, C-Netz, included a card with a chip referred to as a “smart card.” This greatly boosted its capacity.

In 1989, the responsibilities of the GSM were transferred to the European Telecommunications Standards Institute (ETSI). In 1991 the first GSM network was launched by Radiolinja in Finland with joint technical infrastructure maintenance from Ericsson. By the end of 1993, there were over one million subscribers using GSM phone networks. At the time, 70 carriers across 48 countries were in place.

In 1993, Telecom Australia deployed a GSM network outside of Europe and the first hand-held GSM mobile phone was released. In 1995, data, fax, and SMS messaging services became commercially available. The first 1900 MHz GSM network became operational in the US. In 1996, pre-paid GSM SIM cards were launched. In 1998, GSM subscribers surpassed 100 million.

In 2000, the first commercial GPRS services were launched. In addition, the first GPRS compatible handsets were released. In 2002, the first multimedia messaging services (MMS) were introduced. Also, the first GSM network in 800 MHz frequency band became operational. A CDMA SIM card called the R-UIM or Re-Useable Identification Module was made available in China in 2002. It will eventually be available across the globe. In 2004, GSM subscribers exceeded 1 billion worldwide.

By 2005, GSM networks covered more than 75% of the global cellular network market. There were over 1.5 billion subscribers. In 2007, the launch of the first HSUPA network took place.
