UM980 ultraLight GNSS Smart Antenna for precision and RTK positioning.
UM980 ultraLight RTK GNSS Smart Antenna is a next-generation, ultra-lightweight RTK GNSS solution built around the powerful Unicore UM980 module, integrated with a high-precision RM3100 compass and a compact helical antenna. It is purpose-designed for weight-sensitive UAVs, robotics, and mobile applications where every gram matters.
With its advanced multi-band RF front-end, the UM980 ultraLight Smart Antenna is capable of simultaneously tracking all four major GNSS constellations — ensuring robust positioning and centimeter-level accuracy when combined with correction data.
Engineered for flexibility, it supports concurrent reception of GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS, delivering a high-performance navigation solution even in challenging environments. Thanks to its exceptional sensitivity, fast acquisition times, and built-in interference suppression, the UM980 ultraLight provides reliable, high-precision positioning where traditional receivers struggle.
Lightweight, powerful, and dependable — the UM980 ultraLight RTK GNSS Smart Antenna is the ideal choice for next-generation UAVs, autonomous systems, and precision applications that demand top-tier performance without compromise.
