Software Upgrades to the Time and Frequency Reference Measurement Systems

The Fleet Logistics Center Norfolk is seeking information for planning purposes to identify qualified and experienced sources to provide software upgrades for Time and Frequency Reference Measurement Systems (TFRMS). The TFRMS is a rack-mounted unit with various external interface cards, oscillators, and GPS Receivers. The software upgrades are needed to accept input from new TRACER Modem as an external reference. The solution provided to support the TRACER modem will also support other types of external reference sources. • The contractor shall modify the TFRMS software to accept input from the new TRACER Modem as an external reference. • The TFRMS will provide 1PPS, 10MHz (Sinewave) and IRIG (B127) as reference inputs to the Modems from the existing TFRMS hardware interfaces. • The Modems will output offset data with picosecond resolution once per second via a 100Mbps Ethernet interface for 8-channels of source data. • The contractor shall present final report(s) to the USNO technical lead for acceptance.
