The GPS in I use daily paper

Modern receivers GPS have caught up of the costs many contents. After the cellular telephone we are assisting to the spread of a new one cult: that one of the navigator to satellitare personal. The market by now offers to solutions to low cost for all employs it and all the pockets that are not only revealed effective for navigation to satellitare in himself and himself, but also for civil uses, for the monitoring of the services you furnish and for the control of the territory. Several solutions exist:

* Integrated: they are devices portable you All-in-One that they incorporate a receiver GPS, display a LCD, a loudspeaker, the processore who executes the instructions, dates usually from an operating system owner, one slot for memory cards where memorizzare the cartography.
* Hybrid: they are devices portable you (PC, Palmari, SmartPhone) that, been born for various, rendesi scopes they are adapted to navigation to satellitare through the connection of an external receiver GPS (Bluetooth or via cable) and the adoption of a dedicated software, in a position to managing the cartography.

With the capillary spread of systems GPS, and the consequent discouragement of the costs of the receivers, many producers of cellular telephones have tried to insert a module GPS to the inside of their products, opening themselves therefore to the new market of services LBS (Location Services Base, services base to you on the positioning). Such services come more and more take advantage of in order to offer to you also on web of the services the many profits. However, the relative slowness with which GPS finishes them acquires the own position at the moment of the ignition (in average, between the 45 and 90 second ones), due to the necessity to try the satellites in sight, and consequent the remarkable engagement of energetic resources hardware and, has refrained at first this type of coupling. In the last years, but, it has been introduced in this type of telephones the system Assisted GPS, saying also "A-GPS", with which it is possible to obviate to such problems: they are made to reach finishes them GPS, through the net of mobile telephony, the information on the visible satellites from the cell to which the customer it is coupled. In this way a telephone A-GPS can in little second ones gain the own position begins them, in how much is assumed that the satellites in sight from the cell are same the visible ones from finish them under its cover radio. Such system is much profit also like emergency service, as an example in order to localize means or wounded persons later on to an incident.
