Description

Low-noise frequency & time reference for precision timing and navigation systems

TIC is a compact, high-resolution time interval counter designed for the characterization, comparison and continuous monitoring of 1PPS timing references.

Featuring seven physical inputs and twenty-one softwaredefined comparison channels, it enables flexible real-time analysis of time offset and timing drift between multiple
timing sources.

TIC is based on a fully digital architecture with FPGA-based signal processing providing precise, real-time measurements through digital signal processing. The underlying technology is field-proven in operational frequency and timing systems deployed in deep-space ground-station infrastructures.

 

Applications

  • Time scale generation and UTC(k) laboratories
  • GNSS and PNT infrastructure
  • Space ground segment timing diagnostics
  • Optical and quantum timing networks
  • Atomic clock characterization and comparison
