Pedair-seren aml-Band Arolwg antena 40dBi GPS GLONASS Beidou Galileo
Cyflwyniad Cynnyrch
Antena prawf allanol aml-amledd pedair seren: Gall yr antena dderbyn signalau GPS L1 / L2, GLONASS G1 / G2, Beidou II B1 / B2 / B3, ac mae'n gydnaws â band amledd system GALILEO E1 / E5a / E5b.Gellir ei ddefnyddio'n helaeth mewn arolwg geodetig, adeiladu pontydd, adeiladu ffyrdd, seilwaith, arolwg cefnfor, arolwg tir tanddwr, prawf ffordd ysgol yrru, gweithrediad cynhwysydd terfynell ac achlysuron eraill.Yn addas ar gyfer meysydd arolygu a mapio manwl uchel tair system a phedair system.·
Mae gan yr antena gywirdeb uchel, oedi isel, cynnydd uchel, cynnydd da ar onglau drychiad isel, polareiddio cylchol ongl lydan, a chanolfan cyfnod sefydlog.Mae'r rhan antena yn mabwysiadu cynllun dylunio aml-borthiant i sicrhau bod y ganolfan gam a'r ganolfan geometrig yn cyd-daro, gan leihau effaith yr antena ar wallau mesur a gwella cywirdeb mesur.Modiwl mwyhadur swn isel wedi'i gynnwys.
