UM980

GPS/BDS/GLONASS/Galileo/QZSS All-constellation Multi-frequency High-precision RTK Positioning Module
multi frequency

Brief Introduction

UM980 is Unicore's new-generation proprietary high-precision RTK positioning module based on the GNSS SoC NebulasIV which integrates RF, baseband and high-precision algorithm. The module supports GPS, BDS, GLONASS, Galileo, QZSS, NavIC and SBAS. The built-in multi-frequency anti-jamming technology enhances RTK calculation on multiple modes and frequencies, which significantly improves RTK initialization time, measurement accuracy and reliability in complex environments such as city blocks and tree shades. UM980 is well suited for high-precision navigation and positioning applications such as precision agriculture, surveying and mapping and so on.  

Features

  • Based on Unicore's proprietary GNSS SoC NebulasIV that integrates RF, baseband and high-precision algorithm

  • All-constellation multi-frequency RTK engine and advanced RTK technology

  • Instant RTK initialization technology

  • Excellent anti-jamming and anti-spoofing capabilities, supporting jamming detection and spoofing detection

  • Heading2 technology to provide orientation information

  • STANDALONE single-station high-precision positioning technology

  • Supports B2b-PPP, E6-HAS and QZSS L6E (MADOCA) PPP
