GPS Goedetic Trimble R4s GNSS System

Solusi GNSS Trimble R4s telah dirancang untuk memenuhi kebutuhan profesional geospasial di semua aplikasi dan dalam semua kondisi. Rumah receiver yang kokoh dan tahan benturan dapat dengan mudah menahan jatuhnya tiang 2m dan desain tahan air (IP67) dapat menangani kondisi luar ruangan yang paling sulit.

Receiver generasi baru ini dilengkapi radio UHF 2W internal dan antena di dalam batang yang dipatenkan yang tidak hanya melindungi antena, tetapi juga memperluas jangkauan radio RTK.

Koreksi yang dikirimkan melalui satelit dengan akurasi tinggi dari layanan Trimble CenterPoint RTX tersedia melalui L-Band dan IP. Dengan menggabungkan ini dengan pelacakan semua sinyal yang unik dan pemrosesan teknologi Z-Blade GNSS-centric, R4s memberikan pengukuran yang paling andal dan akurasi setinggi mungkin – dalam semua kondisi, di mana pun di dunia.

Dikombinasikan dengan pengontrol Trimble TSC3 yang kuat, perangkat lunak lapangan Trimble ACCESS, dan perangkat lunak perkantoran Trimble Business Center (TBC), sistem GNSS R4s adalah solusi survei lapangan hingga akhir yang lengkap yang akan memenuhi permintaan Anda.
