Overview
UM621N is a GNSS dual-frequency module with MEMS integrated navigation. It is
designed for automotive applications based on the multi-system, dual-frequency and
high-performance GNSS SoC – UFirebird II (UC6580A), which is independently
developed by Unicore Communications, Inc. With the built-in six-axis inertial navigation
device, the module supports multi-system dual-frequency joint positioning and single
system standalone positioning, and can output GNSS+MEMS combined positioning
results continuously even in tunnels and underground garages.
The chip of UM621N conforms to the requirements of AEC-Q100, and the manufacturing
process is in line with IATF 16949.

*
* The default data update rate is 1Hz, which can be configured to 10 Hz or 20 Hz, and the 20 Hz needs
to be supported by specific firmware.
* NAVIC is supported by specific firmware.
