Critical Infrastructure (CI) owners and operators and other users who obtain Coordinated Universal Time (UTC) from Global Positioning System (GPS) devices should be aware of the GPS Week Number (WN) rollover events and the possible effect a GPS WN rollover event may have on the reliability of the reported UTC.

Congratulations to GMA’s Matthew Fishman for winning Spectracoms Sales Representative of the year!

GS-301 Now Certified to work within Federal Aviation Administration (FAA) control centers!

Accurate yet affordable, the Model GS-301 is a rackmount GPS Time and Frequency Receiver with functionality for Network Time Server and Time Code applications. The GS-301 is an excellent choice for applications requiring a single box performing specific tasks without asking you to buy an overbuilt unit with features you simply don’t need.

Time and rate outputs are precisely referenced to GPS or time code input. The GS-301 can optionally synchronize to a 1PPS input. In addition to SNTP and PTPv2 operation, IRIG A, B, G and NASA36 time code outputs are available. Additionally, we offer as an option a 10 MHz sinewave. Time and status are available on the USB port.

The GS-301 will synchronize to GPS to less than 1 microsecond and can provide local or daylight savings time with settable timing offsets. This unit can be paired with our TT-101 for PTP packet timing conversion to a time code or 1PPS. Computer synchronization can be accomplished with optional Domain Time II software.

This versatile product also has a 1PPS Time Interval Measurement feature that will graph the difference between the internal 1PPS and an external 1PPS rising edge.
