什么是(shi)(shi)(shi)(shi)(shi)(shi)免(mian)配卡(ka)GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)，免(mian)配卡(ka)GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)是(shi)(shi)(shi)(shi)(shi)(shi)什么意思-汽車GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)有(you)(you)了(le)解的(de)車友們明白，定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)是(shi)(shi)(shi)(shi)(shi)(shi)務(wu)必安裝一個(ge)(ge)手機(ji)電(dian)話卡(ka)才(cai)能(neng)(neng)夠(gou)實(shi)(shi)現大家(jia)所指的(de)位(wei)(wei)(wei)(wei)置(zhi)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)等作(zuo)用的(de)，那店家(jia)聲(sheng)稱的(de)免(mian)配卡(ka)是(shi)(shi)(shi)(shi)(shi)(shi)蒙騙顧客嗎，其實(shi)(shi)也(ye)不能(neng)(neng)這么說，因為在(zai)這里會(hui)涉(she)及到(dao)GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)的(de)某種工作(zuo)運行原理：GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)自(zi)身(shen)是(shi)(shi)(shi)(shi)(shi)(shi)不用電(dian)話卡(ka)的(de)，它自(zi)身(shen)就(jiu)(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)一個(ge)(ge)完整的(de)體系，只(zhi)需(xu)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)是(shi)(shi)(shi)(shi)(shi)(shi)有(you)(you)電(dian)的(de)，能(neng)(neng)夠(gou)收(shou)到(dao)3個(ge)(ge)以上的(de)衛星(xing)的(de)信號(hao)就(jiu)(jiu)能(neng)(neng)夠(gou)實(shi)(shi)現定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)，但這些定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)是(shi)(shi)(shi)(shi)(shi)(shi)一個(ge)(ge)雙向的(de)過程，也(ye)就(jiu)(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)說定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)接收(shou)信息(xi)(xi)，也(ye)需(xu)要把自(zi)身(shen)的(de)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)信息(xi)(xi)依靠(kao)設備傳送出去，進而明確(que)GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)所處的(de)位(wei)(wei)(wei)(wei)置(zhi)，要是(shi)(shi)(shi)(shi)(shi)(shi)沒有(you)(you)手機(ji)電(dian)話卡(ka)，也(ye)就(jiu)(jiu)相(xiang)當于沒網絡，GPS定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)的(de)信息(xi)(xi)內容就(jiu)(jiu)無法和其他(ta)設備實(shi)(shi)現共享。

服務平臺是查車的載體，是處理設備信息的工作區，僅有依靠服務平臺，才能夠將定位信息分析成中文地址，實現歷史軌跡，電子圍欄，移動端查車等功能，因此說，GPS定位器、手機電話卡、服務平臺是一個三角形互相依靠的關系，缺一不可，店家通常宣傳的免配卡是由于GPS定位器生產商早已將電話卡內嵌，也就是在生產的時候就把卡的芯片直接焊接到主板了，簡化了客戶使用的操作步奏，因此所謂的免配卡GPS定位器也并不是不用自己花錢，只是“羊毛出在羊身上”，購買的錢早就算在定位器的價錢里邊，此外務必留意的是，店家配備的卡通常會贈予一定時間的免費流量使用，以后是自己續費的，且通常以年收費，但這些收費遠低于大家平時了解到的數據流量收費，因此使用的時候也不用過多擔心。
