GEODETIC TRIMBLE R4

Detil Produk dan Spesifikasi GPS Geodetic TRIMBLE R4 Jual Trimble R4 GPS Geodetic, yang digunakan untuk menentukan batas daerah yang berupa perairan, yakni dengan membuat pilar di kedua daratan masing-masing daerah ( disebut titik pangkal perairan) . Selanjutnya dari titk-titik pangkal tersebut, dengan metode penentuan batas tertentu yang dapat menentukan batas antara kedua daerah. Perangkat ini dirancang dengan teknologi GNSS yang mudah digunakan. Sistem 220 channel dengan teknologi Trimble R-Track untuk pelacakan satelit. Fleksibilitas untuk memilih dukungaan GNSS yang sempurna untuk aplikasi anda. Semua yang anda butuhkan untuk melakukan survey dasar. Ringan dan mudah digunakan. Antena dengan frekuensi ganda untuk meningkatkan kapasitas pelacakan. Dilengkapi dengan standar GPS L1, L2, L2C dan QZSS. Pemilihan dukungan GNSS yang anda butuhkan dengan pilihan upgrade yang fleksibel termasuk Glonass, Galilelo dan Beidou. Terintegrasi dengan teknologi Trimble R-Track yang memberikan kinerja posisi yang tepat.
