GPS L1 L5 & Beidou B1 Fafaga Nofofua fa'aputu fa'aantenna
Folasaga o oloa
O le fa'aputu fa'apipi'i antenna ose ituaiga antenna e masani ona fa'aoga i fa'aoga GPS.Ua mamanuina e fa'agaioi i luga ole laina ole L1 ma le L5, o laina fa'aoga ia o lo'o fa'aogaina e satelite GPS mo le fa'atulagaina ma le folauga.E le gata i lea, e fetaui lelei ma le IRNSS (Indian Regional Navigation Satellite System) fa'aigoa alavai.
O se tasi o faʻamanuiaga autu o le faʻapipiʻi faʻapipiʻi antenna o lona lapoʻa faʻatusatusa, fuaina naʻo le 25 * 25 * 8.16 mm.O le mea lea e talafeagai ai mo le tuʻufaʻatasia i totonu o masini laʻititi ma faʻaogaina tekinolosi e masani ona faʻatapulaʻaina avanoa.O le isi vaega taua o lenei antenna o lona maualalo axial ratio.
Talosaga masani e aofia ai:
– RTK
– Mea fa'alavalava
– Felauaiga
– Faatoaga
– Tautai
– Puipuiga
– Taavale Tutoatasi
