UT4B0 is the high-precision timing board developed by Unicore Communications, targeting global high-precision timing application, e.g. telecommunication, power grid, banking, financial transactions (time stamps) and scientific applications. By employing a single UC4C0(432 channel tracking) baseband chip and a single RF chip, UT4B0 can simultaneously track BDS B1/B2/B3 + GPS L1/L2/L5 + GLONASS L1/L2 + Galileo E1/E5a/E5b with high accuracy positioning and timing output.
