Antena ya Utafiti wa Bendi nyingi ya nyota nne 40dBi GPS GLONASS Beidou Galileo
Utangulizi wa Bidhaa
Antena ya majaribio ya nje ya nyota nne ya masafa mengi: Antena inaweza kupokea mawimbi ya GPS L1/L2, GLONASS G1/G2, Beidou II B1/B2/B3, na inaoana na bendi ya masafa ya mfumo ya GALILEO E1/E5a/E5b.Inaweza kutumika sana katika uchunguzi wa geodetic, ujenzi wa daraja, ujenzi wa barabara, miundombinu, uchunguzi wa bahari, uchunguzi wa ardhi ya chini ya maji, mtihani wa barabara ya shule ya kuendesha gari, uendeshaji wa chombo cha mwisho na matukio mengine.Inafaa kwa mifumo mitatu na mifumo minne ya upimaji na uga wa ramani za usahihi wa hali ya juu.·
Antena ina usahihi wa hali ya juu, ucheleweshaji wa chini, faida kubwa, faida nzuri katika pembe za mwinuko wa chini, mgawanyiko wa mviringo wa pembe pana, na kituo cha awamu thabiti.Sehemu ya antenna inachukua mpango wa kubuni wa malisho mbalimbali ili kuhakikisha kuwa kituo cha awamu na kituo cha kijiometri kinapatana, kupunguza athari za antenna kwenye makosa ya kipimo na kuboresha usahihi wa kipimo.Moduli ya amplifier ya kelele ya chini iliyojengwa ndani.
