The United States Naval Observatory (USNO) is the authoritative source of time for the Department of Defense. For this purpose the USNO’s Precise Time Department maintains an ensemble of high-performing atomic clocks that is used to generate precise time. Because of the lack of commercial vendors for the highest performing clocks, stocking the clock ensemble with systems based on cutting-edge technology requires that these systems be designed and built in-house.

The Contracting Department, NAVSUP Fleet Logistics Center (FLC) Norfolk, VA, 23511-3392, intends to solicit and award a commercial firm-fixed-price, sole source purchase order for the procurement of a cold source atomic beam oven(s) and diode laser system in support of the United States Naval Observatory (USNO), under FAR Part 13, Simplified Acquisition Procedures for Certain Products and Commercial Services. The Government intends to solicit and negotiate with only one source, AOSense, Inc. The authority for use of other than full and open competition is FAR 6.302-1, only one responsible source and no other supplies or services will satisfy agency requirements.
