Bill Tang, the original DARPA program manager, now a professor at the University of California, Irvine, also emphasized the importance of military support. The second stage will aim to create a larger transportable version that can be used in a Navy ship or field unit that is accurate to a nanosecond for up to 30 days without an outside GPS signal.Read more of this story at Slashdot. Given that the entire market for atomic clocks is on the order of 200 million a year, it would have been hard for industry to supply the funding for this work from internal R&D budgets.

This clock would be small enough to install in a fighter jet or satellite and tough enough to withstand the temperatures, acceleration, and vibrational noise of such an environment. The applications could be for atomic clocks, where you have an ensemble of atoms you’re vibrating to extract time information, Ale Lukaszew, program manager in DARPA’s defense sciences.

To do this, ROCKn will first look to produce a robust, high-precision small portable optical clock that can maintain picosecond accuracy for 100 seconds at a time. Not only that, they will be more precise and accurate than current state-of-the-art atomic clocks. The goal of DARPA's ROCKn program is to study the basic physics of the principle behind the optical clock and find a way to make optical atomic clocks with low size, weight, and power (SWaP). ROCkN expects to replace GPS atomic clocks with practical, super-accurate optical atomic clocks with low size, weight, and power (SWaP) that can be used outside of the laboratory evironment. Such optical atomic clocks have been built, but they're still huge, delicate, room-filling machines that aren't practical for military application. DARPA has launched its Robust Optical Clock Network (ROCkN) program with the aim of creating optical atomic clocks to improve time synchronization. The ROCkN program builds on two decades of advancement of optical atomic clocks in the lab with the goal to develop technologies that can operate in the field.

In fact, such optical clocks are so accurate that the most advanced wouldn't gain or lose a second through the entire lifespan of the universe. New Atlas reports: Ignoring a lot of technical details, a conventional atomic clock works by using a beam of microwaves to measure the frequency of the target atoms, but by replacing the microwaves with light, the accuracy is boosted by a factor of 100. DESCRIPTION: Frequency and timing devices are essential components in modern military systems. DARPA has announced a new initiative called the Robust Optical Clock Network (ROCkN) program, which will look to develop a practical, super-accurate optical atomic clock that is robust and small enough to fit inside a military aircraft, warship, or field vehicle. The scientists at DARPA will next month detail a new program the group hopes will develop small, portable, battery-powered atomic clocks with stability, repeatability, and environmental. OBJECTIVE: Develop a laser-cooled microwave atomic clock with small volume (<1 L) and weight (<1 kg), low power consumption (<5 W), and the stability (10-12 at 1 s) of a primary atomic frequency standard.
