Custom Timing Systems

Symmetricom designs and integrates complex timing systems to meet a wide range of applications. Systems that meet various levels of redundancy, provide multiple time and frequency outputs and apply the most accurate GNSS and SatCom techniques for measuring offsets between geographically dispersed clocks.

All the hardware and software algorithms required to implement these systems have been developed by Symmetricom and are backed by an extensive support network that includes, installation services, training, and long term maintenance.

Key Features

Symmetricom works with customers through each phase of the project life cycle to define and provide:

• Derivation of specs
• Design
• Reliability analysis
• Hardware
• Software
• Rack integration
• Acceptance testing
• Site installation
• Training
• Long term maintenance

Some examples of recent timing systems delivered by Symmetricom.

	India Regional Navigation Satellite System Redundant timing and distribution system that computes a local time scale from multiple hydrogen masers and cesium atomic clocks and distributes precision time and frequency signals to multiple locations.
	Loran C Timing for Loran-C transmitter. System provides UTC recovery, computes local time scale from three cesium clocks and steers the timescale to UTC(USNO). Built in redundancy is provided along with local remote monitoring and control.
	Two-way Fiber-optic Timing System Campus Campus wide timing system providing sub-nanosecond accuracy and 30-picosend stability. Software allows central monitoring of fifteen slave locations and collects fault information on any of the 1,500 signals provided to user equipment.
