UM220-IV L is a timing module developed for telecom timing and electrical power grid timing, supporting GPS, BDS, GLONASS, and Galileo. The module is based on Unicore's proprietary low-power SoC-UFirebird UC6226, and supports multi-mode timing. It features high accuracy, high stability, high reliability, and is suitable for large-scale GNSS timing appilications.
