  • Overview

    The ES-103U is a low-cost yet very accurate GPS Master Clock/Time Code Generator. The unit receives time and date information from Global Positioning System satellites and supplies this data to the user in the form of four (4) different types of time code ... IRIG-B, ASCII (RS-232C & USB), SE-TC89 and ESE-TC90. Nine amber LED displays (.55") provide a digital display of the Day of Year, Hours, Minutes and Seconds data. Two (2) One Pulse Per Second outputs and a GPS "Lock" output are also standard features. A twelve-channel receiver is employed that is capable of tracking up to twelve (12) satellites simultaneously, although reception of only one is required for time data to be output. Several options are available that allow the unit to meet most any demand required of a Master Clock or Time Code Generator.

    The IRIG-B time code protocol is used in many commercial and industrial applications including military, government, and utility power for its precise time synchronization. Time information is pulse-width coded in either a BCD or binary format.
