Four-star multi-Band Survey antena 40dBi GPS GLONASS Beidou Galileo
Pambuka produk
Four-star multi-frekuensi antena test external: Antena bisa nampa GPS L1 / L2, GLONASS G1 / G2, Beidou II B1 / B2 / B3 sinyal, lan kompatibel karo GALILEO E1 / E5a / E5b sistem band frekuensi.Bisa digunakake kanthi akeh ing survey geodetik, konstruksi jembatan, konstruksi dalan, infrastruktur, survey segara, survey terrain ing jero banyu, tes dalan sekolah nyopir, operasi wadah terminal lan acara liyane.Cocog kanggo telung sistem lan papat sistem survey tliti dhuwur lan lapangan pemetaan.·
Antena nduweni presisi dhuwur, wektu tundha kurang, gain dhuwur, gain apik ing sudut elevasi sing kurang, polarisasi bunder sudhut amba, lan pusat fase stabil.Bagean antena nganggo skema desain multi-feed kanggo mesthekake yen pusat fase lan pusat geometris pas, nyilikake pengaruh antena ing kesalahan pangukuran lan nambah akurasi pangukuran.Dibangun ing modul amplifier low-noise.
