UT986 is a new generation of GNSS system-wide multi-frequency, high-precision timing module independently developed by Hexinxingtong. The module integrates filters and linear amplifiers, and has optimized radio frequency structure and interference suppression capabilities. It integrates adaptive anti-interference technology and multi-path suppression technology internally, supports interference detection and deception detection functions, and ensures that the module can still operate in complex electromagnetic environments. Can provide good performance. The module can provide nanosecond-level PPS accuracy, support fixed-point timing, independent optimization timing, and positioning timing, and can still ensure good timing accuracy in complex signal environments.
