GPS receivers are devices that get signals from orbiting satellites in order to determine the location or geographic position. The applications of the Global Position System technology are very large, with GPS receivers functioning for the aviation, the marine, the military and the average consumer. The satellites spin around Earth twice a day, and their number and positioning allow for at least four to be visible at any moment you’d check the sky. The US military was intended to be the primary beneficiary, but the system and all of its applications were opened to the public after a while.

In terms of structure, you can choose between two types of GPS receivers: a category of devices that require computer connection to function, and stand alone units that do not depend on anything else. The highest mobility is achieved with the stand alone devices, which perfectly matches car usage. Such GPS receivers include a pre-installed software with interactive street maps, route info, and minute details on routing directions. For certain regions, you can also get information on points of local attraction with the GPS devices. Garmin, Magellan, Mio, Navigon or TomTom are the companies that make the best GPS equipment available.

The computer-connected GPS receivers need to be installed on a computer to function, but they also match the mobility needs if used on a PDA, smartphone or a laptop. The connection of the two devices together can be established through Bluetooth technology, or with a USB or serial cable. The disadvantage with this kind of GPS receivers is that they don’t have the navigation software included, and the buyer has to get the program separately. Although these GPS receivers seem to be more difficult to work with in the first place because of the installation, they are nevertheless preferred by users because they are cheaper.

Thanks to the GPS receivers we now install on our cars, navigation is facilitated at the maximum: we no longer depend on rudimentary orientation instruments but on the most efficient technology. Not all devices come with full world maps, particularly if you buy GPS modules. Most of the time, the user has to incorporate the map for a region or a country by using the download system of Google Maps for instance. Geo-spatial orientation will no longer be a problem when you have such a travel companion to tell you the best and fastest way to get to destination without the trouble of getting into traffic jams.

Starting from the signal from orbiting satellites, GPS receivers are able to determine the geographic position or location in real time. The applications of the Global Position System technology are very large, with GPS receivers functioning for the aviation, the marine, the military and the average consumer. The satellites spin around Earth twice a day, and their number and positioning allow for at least four to be visible at any moment you’d check the sky. Although initially, the system was planned for the use of the US military alone, it was soon opened to the public for individual, civilian applications.

There are two types of GPS receivers available for purchase: the stand alone GPS receivers and the items that require computer connection in order to function. The highest mobility is achieved with the stand alone devices, which perfectly matches car usage. Pre-installed software with route info, routing directions and maps is part of the built-in features of the most advanced GPS receivers. Some units even allow for updates on the local attractions in certain area. Some of the best sold products in this category are manufactured by Navigon, Garmin, TomTom, Mio or Magellan Navigation.

The computer-connected GPS receivers need to be installed on a computer to function, but they also match the mobility needs if used on a PDA, smartphone or a laptop. Such GPS receivers can be connected either by cables or by Bluetooth technology. You may have to get the navigation software separately from the GPS unit, because less advanced devices do not have it included. Although these GPS receivers seem to be more difficult to work with in the first place because of the installation, they are nevertheless preferred by users because they are cheaper.

Thanks to the GPS receivers we now install on our cars, navigation is facilitated at the maximum: we no longer depend on rudimentary orientation instruments but on the most efficient technology. GPS modules will not include world maps, but that is hardly an inconvenience. The Google Maps program can be used for downloading data for a certain geographical area or country. From the avoidance of traffic jams, an increase in fuel economy and travel comfort to the possibility to choose the best routes possible and receive lots of practical information, GPS receivers are trustworthy travel companions that rarely fail.

While lots of devices are limited to in-car usage, a portable GPS system allows for all the mobility you may need. Non-portable devices are usually older models that require cable links, but the same inconvenience is found with combinations of PDAs or Palms and GPS devices that have to be car powered in order to save battery life. The portable GPS unit is designed according to special standards that allow for outside usage in various  applications and sports such as hiking, climbing, cycling, fishing and the like. Even if the functionality and the features are similar, there are lots of differences between car GPS units and portable GPS systems.

the ease of programming, the detour options and the speed of the satellite connection make the difference in terms of system proficiency. All these make the handheld or portable GPS system models a viable choice with multiple applications. Always buy a waterproof and weather resistant GPS item if you are going to use it in various temperature and outdoor conditions. The new portable GPS system can also be adjusted to car usage because of the design versatility. You can for example use the GPS device to find alternative routes that avoid traffic jams.

How can one know which is the right portable GPS system to buy? You can try the Internet and search for comparisons between the best rated models. There are in fact, web pages that provide comprehensive comparisons, reviews and price information. The pros and cons of different portable GPS system models are discussed, and some other people’s suggestions could be really useful. It is important to stress out the fact that the navigation system should be tested for more than the vocal announcements, although this feature has a considerable significance too.

Keep your personal needs in mind in order to identify the relevance of each feature in the portable GPS system. And since we are talking about a portable device, the size is very important. The GPS device should fit your pocket, since any item with a large screen will have a reduced portability range. Then, the price comes next on our list of criteria to be met. If you are keen on buying a low-priced unit, you could be disappointed when the unit functions only half the time. Last but not least, consider the capacity of the portable GPS system to calculate the remaining time and distance to destination, since such a function could be very useful.
