Kutupa kumagula Ashtech; kodi tingayembekezere chiyani

Nkhaniyi siidadabwitsa kwambiri, m'masiku ano makampani akuluakulu akugula makampani awo, akuphatikizana ndikugawanika mu zidutswa; koma mosakayikira timakhulupirira kuti zikhoza kuchitika ndi kampani imene inapanga zipangizo zomwe tinkagwiritsa ntchito kapena tikukonzekera.

Pa nzeru zanga ndi kuchokera kwa bwenzi labwino lomwe tidawafotokozera, sitiyenera kuopsya. Ndizo zotsatira za kudalirana kwa dziko ndi kusakanikirana kosavomerezeka kwa mawotchi, kukonza ndi mapulogalamu opangira ma data. Palibe chochita ndi momwe iwo analiri mu kufanana kwakeko malo onse (60 mu 11 brand). Chinthu china ndi chakuti mpikisano (kulekanitsa magetsi a China), umakhalabe muzinthu zitatu zazikulu:

  • Europe (Leica)
  • Japan (Topcon)
  • United States (Kutupa)

Koma aliyense wa iwo amachokera ku mbiri yakale yotere yomwe imasonyeza momwe Civil Engineering, kujambula zithunzi, photogrammetry, zojambulajambula, GIS ndi zoyendetsa zakhala zikuphatikizidwa monga ziphunzitso zosawerengeka. Kusintha kwa makanema a CAD / CAM / CAE, makompyuta, zapamwamba ndi intaneti zikuwonjezeka m'njira yochititsa chidwi.

Nkhani ya Leica (Switzerland), ndiye wolowa nyumba za Wild Wilds omwe tidawagwiritsa ntchito ku yunivesite, ndi mbiri yochokera ku 1819, yogwirizana ndi kupanga makamera otchuka a Leitz. Kufotokoza kugula m'munda wa photogrammetry ndi cholinga kutali anagula ERDAS ndi LH Systems mu 2001 Ere Mapper, amaayoni ndi Acquis mu 2007.

Tsopano Hexagon AB (Swedish) ndi mwini wake wa Leica, monga Geomax ndipo posachedwapa adagula Intergraph (2010).

Pankhani ya Topcon (Japanese), amachokera ku 1932; mu 2000 Topcom anagula Javad; Gwiritsani ntchito 2006 ndi Sokkia mu 2008. Chinthu chotsatira chikhoza kukhala kampani ya Chitchaina, yomwe sidziwika bwino m'deralo koma ndi kukula kwa dziko lonse komwe kumatha kukhala ndi Topcon yomwe yakhala yochepa m'magulu ena.

Ndipo mlandu wa Trimble, kumbali iyi ya dziko lapansi ndiposachedwa (1978) koma ndi makampani a kumpoto kwa America. Iye anali ndi mizu ndi Hewlett Packard; mu 1990 imalowa mu phukusi la Datacom, ndiye mu 2000 imagula Spectra Precision ndi TDS, mu 2003 Nikon; mu 2004 MENSI, GeoNav; mu 2005 Pacific Crest, MTS ndi Apache Technologies ndi Applanix.

Kenaka mu 2006 amagula APS, XYZ, Quantm, BitWyse Eleven, Meridian komanso pa mndandanda ... zomwe zikuphatikizapo pakati Definiens mu 2010. Kotero kugula kwa Ashtech mu 2011 sikungokhala chinthu chatsopano -Inde, popanda Magellan amene adagulitsidwa kale-.

Njirazi sizikupha matekinoloje apamwamba koma omwe akukhala opanda ntchito. Kuthamanga kuli kugula Ashtech kuonjezera mpikisano wa Spectra Precision, osati kupha teknoloji ya BLADE, monga momwe ndikumvera pakalipano, tidzawona mtsogolo.

«Kuphatikiza gawo lalikulu la zinthu zopangidwa ndi GNSS ndi maofesi apadziko lonse a Spectra Precision kungapatse ochita kafukufuku zisankho zosangalatsa zatsopano.”

Ndi ichi, kawongoleredwa kuti salinso tidzaona Mobile Mapper 6 kuti Magellan chinali chabe mzere atsopano otchedwa Mobile Mapper 10 ndi 100 Mobile Mapper. Pa MM100 kale Ine ndinali nditayang'ana Masiku angapo apitawo, amapereka masentimita 40 kuyenda ndi osachepera X cm ndi katemera; pamene MM10 ndi yaying'ono kwambiri koma idzagulitsa kwambiri malingaliro a cadastre akumidzi:

leica topcom sokkia magellan trimble gps Izo zikanati kuwona, koma inu basi kulingalira gulu la US $ 1,500 kapena zochepa, ndi WindowsMobile lotseguka, kamera, mapulogalamu GIS, postprocessing ndi kuti akhoza phiri pulogalamu deta za malo ndi bulutufi. Chida champhamvu chotsutsana ndi US $ 2,400 kapena zambiri zomwe zingawononge wogulitsa masitepe popanda kuthekera kwa GPS GIS. Palibe chochita ndi zophweka Mapu a Mapu a 6, ngakhale izi zikuthandiza RTK; wosonkhanitsa magetsi ndi pulogalamuyi ndi Sokkia SSF mapulogalamu angapangidwe

Koma mbali ya Yambitsani 3 zomwe zatsala pang'ono kutha, tidzangowona Promark 100 ndi Promark 200. Kusiyana kwachiwiri ndi koyamba ndikuti PMK200 imagwira ntchito ndi maulendo awiri a GPS, kapena GLONASS ndi GPS pafupipafupi. Samalani, silingathe kupirira GLONASS pafupipafupi.

leica topcom sokkia magellan trimble gps Koma pakati pa GLONASS / GPS yafupipafupi ndi GPS yafupipafupi, ndingasankhe njira yachiwiri -m'madera otentha ku America palibe njira zambiri-.

Zowonjezera Zonse ndi Mapu Mapulogalamu 100 ndi hardware omwe ali ndi zinthu zofanana ndi pulogalamu. Mwa njira, ndizo zida zowonongeka, nkhani yokonza, kuyambira MM100; ndiye mutha kugula chingwe chamkati chachiwiri (pali Promark), ngati mukufuna zambiri muzitha kuphatikizapo mapulogalamu a geodeic a osonkhanitsa ndiye RTK ndipo muli ndi gulu lalikulu.

Tikukhulupirira kuti kugula ndi kwabwino kwa onse.
