To'rt yulduzli ko'p tarmoqli tadqiqot antennasi 40dBi GPS GLONASS Beidou Galileo
Mahsulot taqdimoti
To'rt yulduzli ko'p chastotali tashqi sinov antennasi: Antenna GPS L1/L2, GLONASS G1/G2, Beidou II B1/B2/B3 signallarini qabul qilishi mumkin va GALILEO E1/E5a/E5b tizim chastota diapazoni bilan mos keladi.U geodeziya tadqiqotida, ko'prik qurilishida, yo'l qurilishida, infratuzilmada, okeanni o'rganishda, suv osti erlarini o'rganishda, haydovchilik maktabida yo'l testida, terminal konteynerlarini ishlatishda va boshqa holatlarda keng qo'llanilishi mumkin.Uch tizimli va to'rt tizimli yuqori aniqlikdagi o'lchash va xaritalash maydonlari uchun javob beradi.·
Antenna yuqori aniqlik, past kechikish, yuqori daromad, past balandlik burchaklarida yaxshi daromad, keng burchakli dumaloq polarizatsiya va barqaror faza markaziga ega.Antenna qismi fazalar markazi va geometrik markazning mos kelishini ta'minlash, antennaning o'lchov xatolariga ta'sirini minimallashtirish va o'lchov aniqligini oshirish uchun ko'p beslemeli dizayn sxemasini qabul qiladi.O'rnatilgan past shovqinli kuchaytirgich moduli.
