HOW GPS WORKS IN CARS

Gadgets and Gizmos (India) - - TABLETS -

GPS car nav­i­ga­tion sys­tems can be fac­tory-in­stalled on new

ve­hi­cles or pur­chased as an add-on ac­ces­sory. Com­bin­ing the use

of sig­nals from the satel­lites with in­ter­ac­tive on-board maps,

these sys­tems can plot routes of travel to a given des­ti­na­tion

based on a num­ber of vari­ables. Some of these sys­tems are in­ter-

con­nected with sources of traf­fic in­for­ma­tion, en­abling them to

au­to­mat­i­cally ac­count for con­ges­tion en route while de­ter­min­ing

the best op­tions to reach a des­ti­na­tion. If a driver misses a turn,

these de­vices can quickly cor­rect for the er­ror and present an up-

dated route op­tion. Pro­vid­ing voice or vis­ual in­struc­tions, these

units also can help driv­ers find the near­est gas sta­tion or give tips

on res­tau­rant or shop­ping op­tions.
