UM981

GPS/BDS/GLONASS/Galileo/QZSS All-constellation Multi-frequency RTK/INS Integrated Positioning Module

Unicore's new-generation proprietary RTK/INS integrated navigation module. The module integrates a high-speed floating-point processor and an RTK-dedicated coprocessor, enabling it to output IMU raw data at 100Hz and RTK data at 50Hz, respectively. The on-board MEMS chip and algorithm ensure continuous, high-quality positioning results in GNSS denied environments such as buildings, tunnels, overpasses, and shaded areas. With its high precision and performance, the UM981 is well-suited for surveying and precision agriculture, among other applications.

Features

Based on the new generation GNSS SoC - NebulasIV, which integrates RF, baseband, and high precision algorithm

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

Instant RTK initialization technology

60 dB narrowband interference suppression and interference detection

Heading2 technology to provide orientation information

STANDALONE single-station high-precision positioning technology

Supports B2b-PPP and E6-HAS

On-board MEMS integrated navigation and U-Fusion technology to ensure continuous positioning when loss of lock on GNSS signals
