Akwai kuma filin da ya nuna idan har yanzu yana cikin samarwa.
Dukkan, sai dai Juno Trimble ya kawo software sun hada da: Magellan ya kawo kamfanin Mobile Mapper Field / Mobile Mapper Office kodayake yana goyon bayan ArcPad, Leica Zeno 5 ya kawo Zeno Field / Zeno Office da EGIS Topcon. Daga cikin uku zaka iya ganin cewa mafi iyakance shine Zeno saboda bai yarda da gyaran halayen ba.
Duk sai dai Trimble Juno yana goyon bayan GLONASS
Game da lokacin karɓa na farko na farko, lokaci mafi tsawo shine Trimble Juno (30 seconds), yayin da iyakar shine Leica Zeno 5 (120 seconds). Sauran biyu suna cikin 60 seconds.
Amma ga tsarin sarrafawa, kowa yana amfani da Windows Mobile 6, sai dai Zeno 5 wanda ya kasance mai amfani da Windows CE. Har ila yau, ba ya goyi bayan bayanan da aka tura zuwa uwar garken nesa ba.
Rashin rauni a cikin batir shine Topcon, tare da 5 kawai yayin da wasu ke ba da 8 hours. Ƙaddara idan muka yi la'akari da cewa kwanakin da ake aiki a tsakanin 6 da 8 hours, la'akari da rikitarwa na nisa da kuma sufuri a yankunan da ba su da biyan kuɗi.
Amma haɗin haɗawa ya fi dacewa da Zeno 5, wanda ke goyon bayan igiyoyin archaic da katin GSM don haɗin Intanet.
Kuma dangane da ƙayyadaddun, garantin mafi kyau shine a MobileMapper, wanda ke samar da ƙananan ƙananan ba tare da aiki ba, wanda yake tsakiya tare da mai-aikawa da kuma RTK na raguwa don millimeter. Duk da cewa Topcon na goyon bayan karin tashoshi, ba a bayyana game da daidaito ba.
