I-GPS L1 L5 ne-Beidou B1 Okuphakelayo Okukodwa kustakiwe i-patch antenna
Isingeniso Somkhiqizo
I-antenna yesichibi estakiwe iwuhlobo lothi oluvame ukusetshenziswa ezinhlelweni ze-GPS.Iklanyelwe ukusebenza kumabhendi efrikhwensi ye-L1 kanye ne-L5, okungamabhendi amafrikhwensi asetshenziswa amasathelayithi e-GPS ekumiseni nasekuhambeni.Ukwengeza, ihambisana namabhendi emvamisa ye-IRNSS (Indian Regional Navigation Satellite System).
Enye yezinzuzo eziyinhloko ze-antenna yesichibi esistakiwe ubukhulu bayo obuhlangene, obungu-25*25*8.16 mm kuphela.Lokhu kuyenza ifaneleke ukuhlanganiswa kumadivayisi amancane kanye nobuchwepheshe obugqokekayo lapho isikhala ngokuvamile silinganiselwe.Esinye isici esibalulekile sale antenna isilinganiso sayo esiphansi se-axial.
Izinhlelo zokusebenza ezijwayelekile zihlanganisa:
– RTK
– Okugqokwayo
– Ezokuthutha
– Ezolimo
– Ukuzulazula
– Ezokuphepha
- Izimoto ezizimele
