Brandywine - RG-2111 Redundant GNSS Reference Frequency Generator
- 1U 19” rack mount
- Dual Redundant hot swappable Power Supplies
- Dual GPS Disciplined Modules
The RG-2111 is a redundant reference frequency generator that uses a Global Navigational Satellite System (GNSS) to steer two internal low phase noise OCXO’s. Each GNSS Disciplined Module provides a set of 3 low phase noise 10 MHz sine waves, 1PPS, monitor and control interface to a user interface output panel. If a failure is sensed in one module the unit will switch outputs to the other GNSS Disciplined Module to provide continuous service. These outputs are accurate daily to 1 x 10-12 when slaved to an internal GNSS tracking receiver’s time. Dual redundant hot swappable power supplies make the RG-2111 perfect for military communications, telecommunications and satcom telecommunications.
The RG-2111 is also able to slave to an external 1PPS signal to steer and hold an internal oscillator and clock system precisely in time. The oscillator maintains its high accuracy of time and frequency information even if no satellites can be tracked. Optional dual network ports support NTP time server functionality. A serial data port is provided to report time, date, position, GNSS satellite health and signal strength.
