GPS4 GPS Synchronised Time & Frequency Standard

The GPS 4 is a compact, state of the art time and frequency standard. The ultra-precise time and frequency outputs are referenced to the GPS satellite system. 8 Channel GPS Receiver Frequency Synthesizer High Stability Time & Frequency Outputs Compact Chassis 1PPS and 10MHz Outputs Two Serial Ports IRIG B Time Code Output Sophisticated Oscillator Control Applications for the GPS 4 include precision frequency reference in the telecommunications industry, accurate time standard for power utilities and a time reference for precisely synchronizing computer clocks. The GPS 4 utilizes a high performance 8 channel GPS receiver to discipline an on board, ultra-stable oven controlled crystal oscillator (OCXO). An advanced oscillator control algorithm assures the highest frequency accuracy is obtained. The automatic position-averaging feature makes the best use of GPS when operating in a fixed location. The highly accurate on board oscillator assures excellent holdover performance ensuring accurate time and frequency even during periods when no GPS satellites are being tracked. Two serial data ports are included with the GPS 4. Time and status is provided over one port while status and system control is available over the second port. Four LED status indicators are supplied on the GPS 4 front panel. The status indicators allow a quick visual check of the operating status of the GPS 4. The 1PPS time mark output may be used for synchronizing or calibrating other equipment. The 1PPS pulse is supplied through a standard BNC connector. The rising edge of the 1PPS pulse is on time. A 10MHz sine wave with exceptional purity and superior holdover performance is a standard output. Distribution of precise time to computers, displays and other equipment is made easy by the standard IRIG B time code output. An on-board frequency synthesizer outputs three custom frequencies, (19.6608MHz, 2.048MHz and 1.544MHz) which simplifies system integration by eliminating the need for external frequency synthesizers.
