Personal navigation, vehicle tracking and public transportation have changed a lot with the evolution of the new GPS technology. Any functional GPS receiver gives you access to the orbiting satellites providing information on destination, current location or the shortest route to take. Moreover, new GPS devices provide information on hotels, traffic conditions, ATMS, restaurants and gas stations for the map on which you navigate. Discreet, convenient and highly reliable, the new GPS units represent the beginning of another age in the field of communications and technological development. Although functioning on a set of common principles, GPS units differ according to brand, design and features.

While lots of devices are limited to in-car usage, a portable GPS system allows for all the mobility you may need. Older GPS designs require cabling and combinations either with Palms or PDAs, relying on this adaptation and on car power. A portable GPS system is a unit designed for outside usage either mounted on the bike or motorcycle or carried around when hiking, mountain climbing or jogging. Even if the functionality and the features are similar, there are lots of differences between car GPS units and portable GPS systems.

GPS mobile receivers are devices that get signals from orbiting satellites to identify the location or geographic position. The applications of the global Position System technology are very large, with GPS receivers working for the aviation, the marine, the military and the average consumer. The satellites that the receivers depend circle the globe 2 times a day, and they’re prepared in such a way on the orbit, that at any moment of the day, four of them should be present on the visible sky permitting one to find the right location or direction. Although initially, the system was planned for the use of the US military alone, it was shortly opened to the public for individual, civilian applications.
