High-precision positioning with all-constellation multi-frequency RTK modules

With the UM980, UM982, and UM960 series from Unicore Communications, Rutronik's portfolio incorporates three new proprietary, high-precision multi-frequency RTK modules. They rely on the current generation of the NebulasIV, a GNSS SoC that combines RF, baseband, and high-precision algorithms. This allows accurate and stable positioning performance, which is particularly critical in areas such as deformation monitoring, high-precision GIS, robotic lawnmowers, precision agriculture, surveying and mapping, and intelligent driving.

Combining advanced hardware design and unique algorithms, the modules can support on-chip computation of RTK positioning for all constellations and multiple frequencies. The UM980 module addresses BDS B1I/B2I/B3I/B1C/B2a/B2b, GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b/E6, QZSS L1/L2/L5, NavIC L5 and SBAS. With the UM960 and UM982 modules, the following frequencies are served: GPS L1/L2/L5, BDS B1I/B2I/B3I, GLONASS G1/G2, Galileo E1/E5b/E5a, QZSS L1/L2/L5 and SBAS.

The UM982's main and secondary antennas also enable it to simultaneously track multiple frequencies of all GNSS systems, perform on-chip RTK positioning, and calculate dual-antenna heading.

UM960 and UM980 feature an innovative integrated anti-interference unit, which ensures that the module provides reliable and accurate position data even in complex electromagnetic environments, such as urban areas and tree shadows, and enhances RTK initialisation speed.
