Model 3650 GPS Synchronized Time Code Generator

Datachron Inc.650 GPS Synchronized Time Code Generator provides the user with the normal selection of generator outputs; time codes, pulse rates, sine waves, parallel data and computer compatible outputs such as IEEE 488 and RS232C. Its main feature, however is that it automatically synchronizes to universal time via the Navstar Global Positioning System (GPS).

Datachron Inc.650 houses a GPS Receiver and is furnished with an antenna and interconnecting cable. The unit operates on the Civilian L Band, C/A code transmitted by the Navstar Satellites. While Datachron Inc.650 is designed primarily for timing applications, and requires only one satellite to be in view to perform this function, it will also provide precise position information. Four satellites in view are required to determine the precise location of the receiver.

With a satellite in view, Datachron Inc.650 correlates to Coordinated Universal Time (UTC) to better than 100 nanoseconds. During this period it also disciplines its internal oscillator so as to achieve optimum correlation with UTC during those periods when satellite transmissions are not available.

Programming of the unit is accomplished through its front panel keypad. An associated alphanumeric LCD display indicates such functions as programmed data, calculated position and satellite health. A second display, comprised of high intensity LED's, continuously indicates time of year information.

Datachron Inc.650 is available in both desktop and rack mounting configurations.
