Inkanyezi eminingi egcwele i-RTK GNSS antenna
Isingeniso Somkhiqizo
Inkanyezi egcwele i-antenna yokuhamba ngesathelayithi egcwele imvamisa inezici ezingezansi:
usayizi omncane,
ukuma okunembe kakhulu,
Inzuzo ephezulu,
ikhono eliqinile lokulwa nokuphazamiseka.
Idizayini ye-antenna ene-multi-feed ukuze isikhungo sesigaba sizinze.Ngasikhathi sinye, i-antenna iphinde ifakwe ipuleti lokuklinya elinezindlela eziningi, eligwema ngempumelelo ithonya lokuphazamiseka kwesignali ekunembeni kokuzulazula ngokucindezela amasiginali wezindlela eziningi.
I-anti-surge design ingamelana ngempumelelo nokuphazamiseka kwangaphandle okuqinile futhi iqinisekise ukuzinza nokuphepha kwezimpawu zokuzulazula.
Ngaphezu kwalokho, le antenna inezinhlobonhlobo zezimo zohlelo lokusebenza.Kungakhathaliseki ukuthi i-geodetic surveying, i-oceanographic surveying, ukuhlola umzila wamanzi, noma ukuqapha ukuzamazama komhlaba, ukwakhiwa kwamabhuloho, ukudilika kwenhlabathi, ukusebenza kweziqukathi zokugcina, njll., kungaletha izinsiza zokuzulazula ezinembile nezisebenzayo kuzo zonke izigaba zokuphila.
