Ukuzwela: Ukumisa ukuxhumana okusheshayo kuzinzile
Isicelo: Umshini wokuhamba wesikhathi
Ifomethi yedatha:M8N
Umugqa womkhiqizo:GPS
Izithombe ezinhle kakhulu zomkhiqizo:
■ Ikhampasi edidiyelwe
■ Gxila embonini yokulawula indiza, enombhali wayo kazibuthe
■ Usayizi womkhiqizo :25 x 25x 8 mm
■ Isikhulisi sesignali esakhelwe ngaphakathi se-LNA
■ Izinga lemboni 25x 25x 4mm uthi lwe-ceramic oluzwela kakhulu
■ Ikristalu eyakhelwe ngaphakathi ye-TCXO kanye ne-Farad capacitor ukuze kuqale ukushisa okusheshayo
■ 1-10Hz Izinga lesibuyekezo sokuma
1. Incazelo yomkhiqizo
I-F23-U isamukeli se-Beidou / GPS esikwazi ukuthola amasignali esathelayithi ngamashaneli angu-72, ukusetshenziswa kwamandla okuphansi nokuzwela okuphezulu, futhi singathola ngokushesha nangokunembile izimpawu ezibuthakathaka emadolobheni, emihosheni, ezindaweni eziphakeme nakwezinye izindawo. Umamukeli uza nombhali we-geomagnetic, esiza umsebenzisi ukuthi athuthukise umsebenzi ngokushesha okukhulu.
