GPS Hitarget vRTK

Hi-Target vRTK

adalah perangkat GNSS geodetik yang menggunakan metode Real-Time Kinematic (RTK) untuk memberikan akurasi posisi tinggi hingga tingkat sentimeter. Salah satu fitur utama yang membedakannya adalah penggunaan teknologi pemosisian visual dengan kamera ganda, yang memungkinkan pengukuran objek tanpa kontak fisik

Dual Cameras for Image Survey and Live View Stakeout

Non-contact measurement greatly improves the usable range of GNSS and efficient safe operation.
