About this opportunity
The Naval Supply Systems Command (NAVSUP) Fleet Logistics Center Norfolk seeks firmware upgrades to FEI-Zyfer, Inc. Time and Frequency Reference Measurement System equipment at the United States Naval Observatory, with quotes due June 22, 2026 at 12:00 PM EST and an anticipated award date no later than June 30, 2026. This is a sole-source procurement; the justification for restricting competition rests on FEI-Zyfer's proprietary ownership of the firmware and system architecture.
Place of performance is Washington, DC. The requirement involves firmware modifications to 50 TFRMS units to accept TRACER Modem input as an external reference source, supporting the Critical Time Dissemination project. Technical specifications include outputting 1PPS, 10MHz sinewave, and IRIG (B127) reference signals; supporting 8-channel threshold or 16-channel objective offset data transmission via 100Mbps Ethernet with picosecond resolution; implementing single-state Kalman filtering; and modifying GTF Intercommunication firmware for seamless failover. Delivery must be completed by September 30, 2026.
The NAICS code is 334519 (Other Measuring and Controlling Device Manufacturing), small business standard 600 employees. The PSC is 9999 (Miscellaneous Items). This is a combined presolicitation notice and solicitation for commercial supplies under FAR Subpart 12.6; no separate written solicitation will be issued. Questions are due June 17, 2026 at 10:00 AM EST. Evaluation is based solely on price reasonableness, and all quotes must be held firm for 180 days. Prior similar purchases were awarded to FEI-Zyfer in August 2020 and September 2023.
