Unicore UT986 GNSS Timing Module


All-constellation Multi-frequency High Precision GNSS Timing Module



The UT986 GNSS timing module is Unicore’s new-generation proprietary high-precision module working on all systems and multiple frequencies.

The UT986 integrates filters and linear amplifiers, providing optimized RF structure and interference rejection capability. Together with the adaptive anti-interference technology and multi-path suppression algorithm, it supports interference detection and spoofing detection, ensuring that the module continuously provides excellent performance even in complex electromagnetic environments.

The UT986 delivers nanosecond-level PPS accuracy and allows multiple timing modes, including fixed-location timing, optimized-location timing, and positioning timing, enabling exceptional timing accuracy in complex signal
