Precision Timing Device



United States Special Operations Command (USSOCOM), Joint Acquisition Task Force (JATF), has issued a solicitation under its Commercial Solutions Opening (CSO) seeking industry solutions to improve telecommunication reliability in GPS-denied environments.

Specifically, USSOCOM is looking for a solution to ensure aircraft telecommunication devices and other mission equipment (sensors, survivability equipment, etc.) have access to highly accurate time in a GPS-denied environment.  This can be accomplished with an on-board precision timing device or potentially by other means.

Submit solutions IAW the USSOCOM CSO procedures. Submissions will be evaluated IAW with CSO evaluation criteria outlined in the CSO guidance document.  Review Period will be completed NLT 1300 (ET), 3 July 2019.

Successfully evaluated solutions will be advanced to negotiations for a prototype project under 10 USC 2371b or procured under 10 USC 2373 or other non-FAR authorities.

Under 10 USC 2371b, USSOCOM seeks to develop a successful prototype for integration into airframes and will likely issue a non-competitive follow on production contract for mass implementation of the successful prototype to maximize the benefit of the technology.

For any questions, please contact the CSO focal points listed on the main FBO announcement.
