Brief Introduction

UM982 is Unicore's new-generation proprietary high-precision positioning and heading module. Its primary and secondary antennas can simultaneously track multiple frequencies of all GNSS systems, and the module can perform on-chip RTK positioning and dual-antenna heading calculation. The built-in advanced anti-jamming unit ensures that the module delivers reliable and accurate positioning data even in complex electromagnetic environments. Featuring the extraordinary positioning performance and reliability, UM982 is a perfect choice for high-precision navigation and positioning applications such as UAV, autonomous machine and precision agriculture.


Features

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

  • Supports all-constellation multi-frequency on-chip RTK positioning and dual-antenna heading solution

  • Dual-RTK technology

  • 60 dB narrowband interference suppression and interference detection

  • Adaptive recognition of RTCM format differential data

  • STANDALONE single-station high-precision positioning technology

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