The Department of Defense (DOD) is seeking proposals for the topic of "Rapid Scalable Time Synchronization" under the SBIR 24.1 BAA. The Navy branch is specifically interested in developing a rapid time synchronization capability for nodes that use single beam antennas in a GPS denied environment. The goal is to optimize transmit power and minimize total power required while maintaining sub-microsecond accuracy within a mobile, wireless network. The time sync protocol should be scalable to many moving platforms and able to provide accurate solutions even when operating at reduced power. The project duration includes Phase I, where a concept will be developed, and Phase II, where a prototype will be delivered and tested. The technology has potential applications in private sector industries such as transportation and communication. The solicitation is closed, and more information can be found on the grants.gov website.
