2007 IntroductionEngineering is one study that experiences a significant growth at a breakneck speed . At least , on that point are four major engineering palm that slide by spawning new inventions that experience life more than better they are mechanical , material , biotechnology , and electronics engineeringConcerning electronic attention , we spectator that consumer electronics goods become the fastest growing plane section in the industry due to vast number of customers and grocery store opportunity . The some interesting factor that occurs in consumer electronic goods is the portability of electronic equipments convey to surface mount technology that make the miniskirtaturization happensAbout cardinal decades ago , Sony Walkman becomes the popular electronic devices due to their portability features . at one cart ridge clip later take-away harvest-feasts are not limited to unspoiled recordingcassette player but also any other functionality much(prenominal) as mini computer like personal digital assistants (PDAs , digital audio players like the famous iPod , mobile phones , and gadgets that cartel those featuresConcerning the man-portable crossings , this go out discuss about portable GPS (global position system ) in which the expenditure of GPS-enabled harvest-tides has been commercialized in electronics industry . The discussion allow in pioneer of portable GPS products , commercialization , recent implements of GPS-based devices , and lso milestones in GPS technologyHistory of take-away GPSHistorically , GPS that stands for global positioning system was innovated by the U .S . division of Defense (D .O .D ) at a lower place the auspices of Ivan Getting , a Ph .D . in Astrophysics . The send-off GPS for U .S . D .O .D was built at the cost of 12 billion dollars , which o riginally used for transmit-based navigatio! nal system in to help U .S . military forces in navigating land and sea . In to provide extensive service , D .O .D set up eighteen satellites in which the ternary orbital which placed 1200 apart , has six satellites (About , 2007By providing extensive shape of satellite , GPS-enabled devices can ask their reference points (satellite ) in the quadriceps to provide information regarding geographical positions (e .g . longitude , latitude and altitude , true line of longitude up to the matter of meter . The most mature product can provide up to centimeter concatenation ( open Park Service , 2007 . skeleton 1 shows GPS devices that uses for navigation target only . Such devices are common placed in ships , boats construction companies , planesFigure 1 Garmin GPSmap 60 CSource : About , 2007 Currently , the use of GPS becomes value added or features of a product in which GPS-enabled product is integrated with other devices such as cars to direct drivers to animadvert desti nations , mobile phones with appropriate software to inform the nearest ruffle stations or restaurants and also laptop computers (Figure 2The development of GPS-enabled products continues f number up due to the invention of most distinct timepieces , the atomic clocks , which can provide accurate time in the billionth of a second range . agree to National Park Service (2007 , the fast development of GPS-based operate has provided to a greater extent than 100 ,000 new jobs (b Figure 2 Recent GPS-enabled products (a ) rambling phone (b ) WristwatchBright s Model of Innovation...If you indigence to get a abounding essay, order it on our website: BestEssayCheap.com
