Cov locators SIM card thiab xov tooj ntawm tes tuaj yeem nrhiav tau sai.
Txij li xyoo 2012, lub cuab yeej nrhiav tus kheej tau ua tiav qhov tseeb ntawm 5-50 meters, yog li cov neeg siv tuaj yeem paub lawv qhov chaw nyob, thiab tuaj yeem upload thiab download cov ntaub ntawv tib lub sijhawm, yam tsis tas siv cov channel sib txuas lus ntxiv ntawm lub network wireless operator. GIS rau cov ntawv thov lag luam ntawm tus neeg muab kev pabcuam.
Piv nrog rau cov thev naus laus zis GPS positioning ntshiab, Ariza positioning technology muaj cov yam ntxwv hauv qab no hauv kev txhim kho GPS positioning technology:
1) Qhov tseeb siab: nyob rau hauv cov xwm txheej zoo dua, qhov tseeb ntawm qhov chaw tuaj yeem ncav cuag 5-50m.
2) Lub sijhawm luv luv: tsuas yog ob peb feeb mus rau kaum vib nas this kom ua tiav qhov chaw.
