RAB4 - RTK

Real-time kinematics (RTK) is a technology that is much more accurate than conventional multi-GNSS systems and is becoming more and more economically attractive. Only state-of-the-art components from the Rutronik portfolio come into use on the Adapter Board RAB4 - RTK from Rutronik System Solutions. The UM980 from Unicore is a high-precision RTK positioning module based on the latest generation of the GNSS SoC NebulasIV. It offers a high positioning rate of 50 Hz and supports all available GNSS frequencies. Thanks to the integrated anti-interference feature, even complex environments with the threat of multi-path effects like urban areas are no problem. Due to these characteristics, the UM980 suits for high-precision navigation and positioning applications.

To evaluate absolute positioning, the RAB4 features a 4G LTE module with an integrated standard multi-GNSS receiver from Telit Cinterion's LE910 series. Another advantage is that developers can directly compare the outputs of the GNSS receiver with those of the RTK receiver and can draw conclusions about the need for improvements for the respective application without having to use several development kits from different suppliers. The RAB4 also includes a prepaid SIM card preloaded with 100 MB of data. Thanks to this combination, NTRIP correction data can be downloaded from the Internet. It is not necessary to operate an own reference station.
