Purchase Order N0018925P0533

Stanford Research Systems Inc., a small business manufacturer of precision scientific instruments based in Sunnyvale, California, was awarded a $55,084.62 firm fixed-price purchase order by the United States Naval Observatory on September 9, 2025. The contract involves procuring specialized electronic components to support the development of two new fountain atomic clocks, including SIM900 mainframes with RS-232 computer interfaces, rack mount kits, PID controllers, analog summing amplifiers, function generators, and related modules. The procurement was structured as a sole-source acquisition under NAICS code 334519, with Stanford Research Systems identified as the only vendor capable of providing components that precisely match the design specifications of six previously built clocks without requiring additional research and development. Performance will be completed by September 30, 2025, with delivery to the Naval Observatory in Washington, DC.

This procurement supports the Naval Observatory's Clock Development Division mission to maintain and advance the nation's timekeeping standards through atomic clock technology. No small business set-aside designation was used for this award. The Naval Observatory, which maintains the official U.S. time standard and supports critical national defense and civilian positioning, navigation, and timing applications, relies on advanced frequency reference instruments like those provided by Stanford Research Systems through its extensive history of supplying specialized measurement equipment to federal agencies including NASA, NIST, and the Office of Naval Research.
