Description

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

RBX is a high-performance rubidium frequency and time reference designed for precision timing, synchronization and navigation applications. Proven in demanding environments,
including space ground segments, it delivers low phase noise and excellent frequency stability for mission-critical operation.

RBX provides 6x 10 MHz outputs and 4x 1PPS outputs as standard. Optional 100 MHz and 10.23 MHz outputs support high-frequency timing and navigation applications. RBX can be
disciplined via external 1PPS or GNSS inputs, ensuring long-term accuracy while maintaining low noise performance.

A robust architecture with redundant power supply, monitoring, and control interfaces ensures reliable operation and seamless integration into complex timing infrastructures.

 

Applications

  • Ground segments and satellite tracking
  • Time realization and metrology
  • Navigation & GNSS infrastructures
  • Scientific facilities and particle accelerators
  • Test & measurement
