Teknologi Laser Hijau Terbaru
GPS Geodetic Meridian M20L Laser Teknologi laser menawarkan keuntungan tak tertandingi dalam penentuan posisi presisi dan membuat pekerjaan survei tanpa menggunakan tongkat dan lebih mudah. Menggabungkan teknologi laser jarak 100m yang canggih dengan konstelasi penuh GNSS, IMU, dan integrasi 4G, menghasilkan akurasi bebas kalibrasi, yang secara signifikan meningkatkan efisiensi kerja dan mengurangi potensi risiko.
Solusi Bebas Kalibrasi
Dilengkapi dengan laser & teknologi IMU bebas kalibrasi 120° dalam bodi kecil, teknologi ini melengkapi kinerja laser yang luar biasa, memperluas jangkauan aplikasi M20L ke lokasi yang tidak dapat dijangkau oleh sistem RTK tradisional, membuka cakrawala baru untuk aplikasi produk, meningkatkan kepuasan pelanggan, dan meningkatkan efisiensi operasional.
Ukuran Telapak Tangan
Sistem RTK (Real-Time Kinematic) seukuran telapak tangan memadukan keanggunan dengan presisi, menawarkan solusi ringkas untuk penentuan posisi akurat saat bepergian.
Baterai Kuat
Dengan 7.4V 7000mAh dan kemampuan pengisian cepat, mendukung Anda bekerja lebih dari 26 jam dan sangat menghemat waktu Anda.
Konstelasi Penuh
Mendukung BDS, GPS, GLONASS, Galileo, QZSS, SBAS, dan L-Band. Sebanyak 1408 salurannya menawarkan kemampuan pelacakan sinyal GNSS yang komprehensif.

*All specifications are subject to change without notice.(1) Compliant, GLONASS L3, Galileo E6, Galileo E6 High Accuracy Service (HAS), BDS B2b and SBAS L5 will be provided through future firmware upgrade.(2) Accuracy and reliability are determined under open sky, free of multipaths, optimal GNSS geometry, and atmospheric conditions. PPP accuracy is subject to the region, environment, and convergence time. High-precision static requires a minimum of 24 hours of long-term observation and precise ephemeris.
