Ukunciphisa kuthenga i-Ashtech; yini esingayilindela
Izindaba azizange zimangalise kakhulu, kulezi zikhathi ukuthi izinkampani ezinkulu zithenga izincintisana zayo, zihlanganisa futhi zihlukaniswe zibe izingcezu; kodwa ngokungangabazeki siholelwa ukuthi kungenzeka ngenkampani eyenza imishini esiyisebenzisayo noma eyayiyinkimbinkimbi yokuthola.
Ngokubona kwami nangomngani omuhle esabelana naye ngale ndaba, akumele wethuke. Yimiphumela yokusatshalaliswa kwembulunga yonke kanye nokuxubana okungenakugwemeka kobuchwepheshe bokubamba, ukucubungula kanye nokuhlinzeka ngemininingwane ye-cartographic. Akukho okuphathelene nendlela ababeyikho kulokho kuqhathaniswa iziteshi eziphelele (60 kumikhiqizo eyi-11). Iqiniso ukuthi umncintiswano (ngaphandle kobuchwepheshe baseChina), uhlala kwemithathu emikhulu:
- I-Europe (Leica)
- I-Japan (i-Topcon)
- I-United States (i-Trimble)
Kepha ngayinye yazo ivela emlandweni omude kangako ukuthi ikhombisa ukuthi i-Civil Engineering, i-cartography, i-photogrammetry, i-topography, i-GIS, kanye nezokuthutha zihlangane kanjani njengemikhakha engahlukaniseki. Ukuvela kobuchwepheshe be-CAD / CAM / CAE, amakhompyutha, amagajethi futhi i-intanethi yengezwe ngesithakazelo esithakazelisayo.
Icala likaLeica (ISwitzerland), uyindlalifa yaleyo mishini yasendle esiyisebenzise eNyuvesi, enomlando kusukela ngo-1819, ohlotshaniswa nokwenziwa kwamakhamera adumile akwaLeitz. Ukufingqa ukutholwa, emkhakheni we-photogrammetry nokuzwa okukude bathenga i-ERDAS ne-LH Systems ngo-2001 kanye no-ER Mapper, Ionic no-Acquis ngo-2007.

Manje u-Hexagon AB (isi-Swedish) ungumnikazi weLeica, njengoGeomax futhi kamuva nje uthenge i-Intergraph (2010).
Endabeni ye-Topcon (IsiJapane), sivela ngo-1932; ngo-2000 abakwaTopcom bathenga uJavad; UKE ngo-2006 naseSokkia ngo-2008. Isinyathelo esilandelayo kungaba yinkampani yaseChina, engaziwa kangako endaweni yethu kodwa ngokukhula komhlaba wonke okwazi ukumunca iTopcon ebinqunyelwe kweminye imikhakha yezicelo.

Futhi icala le-Trimble, ngakolunye uhlangothi lomhlaba kusanda kwenzeka (1978) kodwa ngobudlova bezinkampani zaseNyakatho Melika. Kwakunezimpande ngeHewlet Packard; ngo-1990 iDatacom yafaka iphakethe, kwathi ngo-2000 yathenga iSpectra Precision neTDS, ngo-2003 uNikon; ngo-2004 MENSI, GeoNav; ngo-2005 iPacific Crest, i-MTS ne-Apache Technologies ne-Applanix.

Khona-ke ku-2006 uthenga ama-APS, i-XYZ, i-Quantm, i-BitWyse Eleven, i-Meridian nokunye ohlwini ... okubandakanya phakathi kokugcina Definiens ngo-2010. Ngakho-ke ukuthengwa kwe-Ashtech ngo-2011 akuyona nje into entsha -Yiqiniso, ngaphandle kukaMagellan obevele ushengisiwe-.
Lezi zinqubo azivame ukubulala ubuchwepheshe obusha kepha zibulala lezo eziphelelwa yisikhathi. UTrimble uthenga i-Ashtech yokwandisa ukuncintisana kwe-Spectra Precision, hhayi ukubulala ubuchwepheshe be-BLADE njengoba ngiyaqonda kuze kube manje, sizobona ngokuhamba kwesikhathi.
“Ukuhlanganisa iphothifoliyo ebanzi ye-Ashtech yemikhiqizo ye-GNSS nenethiwekhi yomhlaba wonke yokusabalalisa ye-Spectra Precision kunganikeza abahloli izinqumo ezintsha ezijabulisayo zokusebenza kahle.”
Ngalokhu, kuyacaciswa ukuthi ngeke sisayibona iMobile Mapper 6 eyayivela eMagellan, kuphela ulayini omusha obizwa ngeMobile Mapper 10 neMobile Mapper 100. KuMM100 vele Ngangibhekile izinsuku ezimbalwa ezedlule, linikeza u-40 cm ekuhambeni futhi ngaphansi kwe-10 cm ngokuthunyelwa kokuthunyelwe; kuyilapho i-MM10 incane kakhulu kepha izothengiswa kakhulu ngezinhloso zasemaphandleni yasemaphandleni:
Kungadingeka ukubona, kepha kufanele ucabange nje ngedivayisi engu-US $ 1,500 noma ngaphansi, eneWindows Mobile evulekile, enekhamera, isoftware ye-gis, ukucubungula ngemuva nokuthi ungahlanganisa uhlelo lokuqoqa idatha lweziteshi ze-bluetooth. Isikhali esinamandla ngokumelene ne- $ 2,400 noma ngaphezulu umqoqi wesiteshi angabiza ngaphandle kokuthola i-GPS GIS. Akukho okuphathelene nabalula I-Map Map 6, yize isekela i-RTK; ngemuva kwesikhashana kungenziwa umqoqi wesiteshi ngale hardware kanye nesoftware kaSokkia's SSF
Ngokuqondene nohlangothi Thumela i-3 okumelwe inyamalale, sizobona kuphela i-Promark 100 ne-Promark 200. Umehluko wesibili nowokuqala ngukuthi i-PMK200 isebenza ngemvamisa ye-GPS ephindwe kabili, noma i-GLONASS ne-GPS ku-frequency eyodwa. Qaphela, ayisekeli i-GLONASS kumvamisa ophindwe kabili.
Kepha phakathi kwe-GLONASS / GPS yemvamisa eyodwa ne-GPS yemvamisa ephindwe kabili, ngingakhetha inketho yesibili -okungenani emahlathini aseMelika awekho izindlela eziningi kakhulu-.
Kokubili i-Promark ne-Mobile Mapper 100 ngamaqembu ane-hardware ne-software efanayo. Ngandlela thile, bayimishini engahlukaniseki, udaba lokumiswa, okuqala ngeMM100; lapho-ke ungathenga i-antenna yemvamisa embaxambili yangaphandle (lapho une-Promark), uma ufuna okuningi, ungahlanganisa isoftware ye-geodetic yomqoqi bese kuba yi-RTK futhi uneqembu elikhulu kakhulu.
Sethemba ukuthi ukuthenga kungokuhle kwabo bonke.
Kuhle kakhulu ulwazi lwakho, ngiyabonga
