ALPHAGEO LR9

  • HIGH-PERFORMANCE GNSS REFERENCE RECEIVER

    ALPHA GEO LR9 merupakan GNSS Reference Receiver berperforma tinggi dengan desain split-type yang dilengkapi chipset GNSS generasi terbaru dengan konsumsi daya rendah dan performa tinggi.

    Mendukung penerimaan sinyal satelit multi-frequency dan multi-constellation, LR9 memanfaatkan teknologi carrier-phase differential positioning melalui metode RTK dan PPK untuk menghasilkan akurasi posisi hingga tingkat milimeter pada pengukuran statik dan tingkat sentimeter pada pengukuran dinamik.

    Dengan performa dan stabilitas yang dirancang untuk kebutuhan survei presisi tinggi, ALPHA GEO LR9 ideal digunakan untuk berbagai aplikasi kritis, seperti:

    • CORS (Continuously Operating Reference Station)

    • Monitoring geohazard dan pergerakan tanah

    • Structural Health Monitoring (SHM)

    • Monitoring deformasi dan pergerakan struktur

    • Aplikasi survei dan pemantauan geospasial presisi tinggi

    Multi-Frequency • Multi-Constellation • RTK/PPK • mm-Level Static • cm-Level Dynamic
