Vula ikhompyutha yakho ephathekayo ibe yindlela ye-GPS
Nakuba wonke amafoni ethu aqukethe i-GPS intenna evumelanisa nathi kumamephu wezwe, amanye ama-laptops embonini akwenzi. Uma udinga isofthiwe ye-GPS ehambile neyinkimbinkimbi khona-ke uzodinga i-antenna enamandla ukuze uxhumane nekhompyutha yakho. Kungakhathaliseki ukuthi uxhuma i-GPS emotweni yemoto ehamba ezindaweni zasemaphandleni ezikude noma ehamba ngesikebhe, lawa ma-USB dongles asekelwe e-USB angumkhakha ohambisana nezinhlelo ezihlukahlukene kakhulu ze-GPS.
I-Garmin yigama lomkhiqizo ekuhambeni kwe-GPS futhi le divayisi ye-USB idinga idumela elihlonishwayo. Le puck encane i-WAAS Inikezwe amandla ukuzwela GPS isamukeli esakhiwa ukuze kusetshenziswe emotweni yomuntu siqu, izimoto zemoto kanye nezicelo ze-elekthronikhi lapho kudingeka khona isamukeli se-GPS. Inamashaneli angu-12 ahambisanayo kanye nesisekelo esihlanganisiwe se-magnetic, okhiqiza idatha embonini ejwayelekile ye-NMEA 0183. I-unit latency ephansi, okusho ukuthi ilungele izinhlelo zokusebenza zemoto ezidinga ukuvuselelwa ekuhambeni. I-Industry-standard accuracy 10-foot ibuye iqinisekise ukuthi ngeke ube kude uma usebenzisa le divayisi, esebenza kakhulu nesofthiwe yesimanje.
Lo mdwebo ojwayelekile usebenza ngendlela efanayo neGarmin, kodwa ngaphandle kwemali ephakeme. I-USB-isekelwe icala le-magnetic kanye nobude bekhebula elingamamitha angu-6.5 elimelana nezakhi. Isebenza esimisweni sezinga le-NMEA 0183 embonini futhi ihambisana nesofthiwe yokuhlola yamahhala ye-GNSS futhi isekela amamephu we-Google noMhlaba. Idivayisi nayo ine-56 isiteshi esilandelayo sokubuka kokulandela. Unesignali eqinile ne-latency ephansi, okwenza kube ekahle ekusetshenzisweni komthetho.
Le-antenna ye-GPS ipakethe ibilokhu ikhonza abanikazi bezintambo nabanethiwekhi bekhompuyutha iminyaka eminingi. Idivaysi ye-compact inikezwa yi-chipset ezwelayo kakhulu enganikeza ukusebenza okuphakeme noma ngabe ungaphakathi kwedolobha noma ngaphandle kwezwe. Vele uxhume i-USB ku-PC yakho noma ku-Mac yakho bese uhlanganisa amandla we-SiRF Client Generated Extended Ephemeris (ubuchwepheshe be-CGEE), ongakwazi ukubikezela indawo ye-satellite kuze kube yizinsuku ezintathu kusengaphambili bese uvuselela ngokuzenzakalelayo njalo imizuzwana engu-15. Idivaysi yakhiwa ngetemitha engakwazi ukunamathela phezulu emotweni yakho futhi ingakwazi ukumelana kokubili kwamazinga okushisa nokushisa okungavamile, ngakho-ke akudingeki ukhathazeke ngokuvezwa okuyisisekelo.
Thatha i-GPS nawe kule-usb encane encane ene-LNA eyakhelwe ngaphakathi ne-antenna ye-GPS eyakhelwe ngaphakathi. Mayelana nobungako bokushayela kwesithupha, leli divayisi ye-GPS isekela imboni ejwayelekile yeNMEA 0183 no-SBAS. Ihambisana namahlelo wokusebenza we-Mac, i-Windows ne-Android futhi ihambisana nayo yonke i-software ye-navigation ye-NMEA, ikuvumela ukuthi ukhethe uhlelo lokusebenza noma uhlelo lokusebenza oluhle ukudala isixazululo sakho esihle se-GPS.
Ubuzwe obuphezulu MediaTek GPS chipset inesikhathi esisheshayo kakhulu sokulungisa kuqala, ngisho nasezingeni eliphansi lesignali, okwenza kube kuhle ezindaweni ezikude. I-GPS ephathekayo i-LED ikutshela ukuthi ngabe idivayisi isebenza, ebuye isebenze ekutholeni indawo.
Le divayisi ilandelela ukuqeqeshwa nokusebenza kwakho, ikuvumela ukuba ulayishe futhi wabelane ngokugijima kwakho, ukuze ukwazi ukukala imizila yakho noma ubuyele kuzo kamuva. Isebenza nokuphathwa kwe-Movescount Daily Training ku-PC noma ku-Mac. Vele uxhume i-USB ngemuva kokugijima futhi ungalayisha yonke idatha yakho kusuka kudivayisi yakho ephephile ye-ANT. Le nkampani igcina imiphakathi e-intanethi ongabelana ngayo ukuze uqaphele inqubekelaphambili yakho futhi usize ekuqeqesheni kwakho, ngakho-ke ukhululeke ukwabelana ngokunqoba kwakho nabangani ngemuva kokugijima kwerekhodi.
Lesi siphetho se-GPS se-GPS esingabizi sibambisana nomkhakha-okujwayelekile, ukuzwela okukhulu kwe-GPS Antenna ne-KDS .5PPM ephezulu-TCXO ecacile. I-RTC chip ne-pF capacitor zenzelwe izikhathi zokuqala ngokushesha ngisho nasezindaweni eziphansi zesignali, kanti izinga lokubuyekeza isikhundla se-1-5 Hz lilungele ukwenza imephu nokuhamba kwemoto. Idivayisi igcina imininingwane yakamuva ye-satellite ngenkathi ithola izimpawu ze-WAAS / EGNOS ngaphandle kwesofthiwe. Ngezinhlelo zokusebenza ezihambisanayo ezifana ne-Google Amamephu ungasebenzisa idatha ye-NWEA0183, okwenza lokhu kube yisisombululo esinokushintshashintshayo futhi esingabizi emotweni yemoto.
Xhuma i-laptop yakho kuze kube ngama-satellite angama-20 nale GPS GPS dongle yama-computer kanye netbooks. Kuyinto encane ye-USB thumb drive esimweni esiluhlaza okwesibhakabhaka ongasinamathisela ku-keychain yakho. Idivayisi inembile ngaphakathi kweyodwa kuya kumamitha amahlanu futhi inesikhathi sokuthola kabusha nje kwemizuzwana .1. Ngesikhathi sokuqala esifudumele esingaphansi komzuzu ngeke kudingeke uchithe isikhathi sokuthola indawo ye-EGNOS / WAAS ye-beacon kusukela ku-antenna eyakhelwe ngaphakathi. I-dongle ihambisana nesofthiwe ye-GPS ehambisana ne-NMEA efana ne-Google Earth futhi ingagcinwa emazingeni okushisa angafika kuma-degree angu-100.
