Unicore UM960 GNSS RTK Module


GPS/GLONASS/Galileo/BeiDou Multi-frequency High-precision GNSS RTK Module



The UM960 high-precision GNSS RTK module is Unicore’s new-generation proprietary high-precision positioning, based on the NebulasIVTM SoC. The UM960 simultaneously tracks multiple frequencies of all G6NSS systems, enabling the module to output high-precision RTK positioning. The built-in advanced anti-interference technology ensures the UM980 delivers reliable and accurate positioning data even in complex electromagnetic environments. Featuring extraordinary positioning performance and stability, the UM960 is a perfect choice for high precision navigation and positioning applications.

UM960 simultaneously tracks signals from GPS, GLONASS, Galileo, BeiDou and QZSS systems and supports tri-band signals from GPS, Galileo and BeiDou and QZSS, delivering “instantaneous” RTK initialization achieving centimeter level
positioning accuracy. In areas of partial signal blockage or over long baseline distance, the UM960 obtains RTK positioning results quickly and reliably.

RTK KEEP technology eliminates the positioning errors affected by satellite orbits, clock difference’s, ionospheric and tropospheric delays by means of models and parameter estimation after the loss of base station data. Centimeter-level positioning accuracy can be maintained for up to 10 minutes.

NebulasIVTM is Unicore’s latest generation proprietary GNSS SoC. By leveraging 22nm process node architecture, high-performance multi-mode baseband processor and embedded microprocessor, NebulasIVTM delivers superb performance and maintains low power consumption. The integrated RTK matrix processing technology allows the chip to deliver an enhanced and robust all- system all-frequency centimeter-level RTK position.
