Chip Scale Atomic Clock
Abstract
Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) systems require precise timekeeping even if the Global Positioning System (GPS) is unavailable. The size, weight, power, and cost components of conventional atomic clocks are too high for tactical applications. Chip Scale Atomic Clock (CSAC) provides improved long-term frequency stability that gets integrated into long-term time accuracy. The focus of this project is to leverage DARPA investments in the CSAC technology to reduce operational costs and transition beyond custom fabrication of the current CSAC. Mass manufacturing capabilities will be enabled with the development of batch processes, manufacturing tools, and automated assembly and test. Development of a network of multiple vendors to foster competition and ensure a viable supply base is a complementary goal. Successful performance will enable an environment of continued operation of critical Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance systems, regardless of the presence or absence of GPS. The ability to rapidly reacquire GPS military code in a hostile Electro Magnetic Interference (EMI) environment is an additional targeted benefit.
