Satellite Timing Units for Absolute Time Tagging and Synchronous Data Sampling

Macrodyne Model 1698E Satellite Timing Unit

Model 1698E Satellite Timing Unit

The use of precise time for both absolute time tagging and synchronous data sampling applications offers significant opportunities towards the enhancement of overall power system performance. The Model 1698E Satellite Timing Unit makes this capability available in a configuration designed specifically to address the critical demands of power system applications.

The Model 1698E derives absolute time information from reliable NAVSTAR Global Positioning System (GPS) satellite transmissions. The Global Positioning System is a worldwide navigation and timing system which is rapidly becoming the electric power industry's preferred time coordination medium.

Operation

Several unique features have been incorporated into the Model 1698E to satisfy the demanding requirements of the power system environment. Clock synchronization signals (and time codes) are available on electrical outputs. The instrument also supports the standard IRIG-B format time code as an output. To provide unattended year round operation the clock can be programmed to automatically adjust for local time changes throughout the year. The Model 1698E can be powered by a DC station battery voltage and is SWC tested to meet the most demanding substation performance requirements. The Model 1698E is designed and developed by Macrodyne, a name synonymous with innovation, reliability and performance within the electric power instrumentation industry.
