GPS+Beidou Timing Antenna Marine Antenna 38dBi
Chiyambi cha Zamalonda
GPS+Beidou Timing antenna ndi mtundu wa mlongoti womwe umagwiritsidwa ntchito polandira ma siginecha a satellite.Ikhoza kulandira ma RHCP ma siginecha a satellite mu magulu a ma frequency a GPS L1 ndi BD B1.
Antenna iyi ili ndi izi:
Kupindula kwakukulu: Mlongoti wa mutu wa bowa ukhoza kupereka kupindula kwakukulu kwa siginecha ndikuwonjezera mphamvu yachizindikiro chofooka cha siginecha yomwe walandira, potero imakulitsa chidwi cholandira komanso mtundu wazizindikiro.
Kukhazikika kwapamwamba: Mlongoti wapangidwa ndi kukhazikika kwapamwamba ndipo ukhoza kusunga ntchito yokhazikika pansi pa zochitika zosiyanasiyana zachilengedwe.Izi zikutanthauza kuti ikhoza kupereka kulandila kokhazikika kwa ma satelayiti munthawi zonse zanyengo.
Malo okhazikika kwambiri: Mlongoti wa mutu wa bowa uli ndi malo okhazikika kwambiri, ndiye kuti, gawo lapakati la chizindikiro cholandiridwa limakhala lokhazikika pakapita nthawi.Izi ndizofunikira kwambiri pakuyika ndi kuyendetsa ntchito, popeza kukhazikika kwapakati kumakhudza mwachindunji kulondola kwa kuyeza.
