Product Description:

UM980

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

The UM980, a cutting-edge proprietary RTK positioning module developed by Unicore, offers high precision and advanced capabilities. This module is compatible with all existing satellite constellations and frequency bands. It boasts a data update rate of 50Hz for RTK, and it also accommodates Precise Point Positioning (PPP), including E6 High Accuracy Service (HAS) and BDS B2b. Given its superior performance, the UM980 is ideally designed for applications requiring high-precision surveying, such as mapping, precision agriculture, and monitoring of structural deformations.

UM980 Application


• Surveying and Mapping	• Precision Agriculture

UM980 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
