Is a next-generation, ultra-lightweight RTK GNSS solution built around the powerful UM980 module, integrated with a high-precision RM3100 compass, and external helix 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 all-band high precision RTK module is capable of simultaneously tracking all major GNSS constellations — ensuring robust positioning and centimeter-level accuracy when combined with correction data. Overview Engineered for flexibility, the UM980 ultraLight multi-band high-precision RTK module supports concurrent reception of GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC, and SBAS, delivering high-performance navigation even in challenging environments. Lightweight, efficient, and reliable, it is an ideal choice for UAVs and robotic platforms requiring uncompromised performance in a compact form factor.
