“The goal is to transition optical atomic clocks from elaborate laboratory configurations to small and robust versions that can operate outside the lab,” said Tatjana Curcic, program manager in DARPA’s Defense Sciences Office. It would also be accurate to a nanosecond precision for 30 days in the absence of GPS. In the second phase, the focus will be on creating a larger transportable version that can be used in a Navy ship or field. Moreover, it should be tough enough, so that it could withstand the temperatures, acceleration, and vibrational noise. It would also be able to maintain pico-second accuracy for 100 seconds at a time. The clock would be small enough to install in a fighter jet or satellite. In the first phase, ROCKn plans to develop a robust, high-precision small portable optical clock. ROCkN program will consist of two separate phases ![]() These clocks are compact enough to fit inside a military aircraft, warship, or field vehicle. ROCkN plans to build low size, weight, and power (SWaP) optical atomic clocks that are practical and super accurate. government agency DARPA has recently announced the Robust Optical Clock Network (ROCkN) program. At times, GPS technology could be jammed by adversaries. For these operations, there is a high reliance on GPS. ![]() ![]() In the war field, a timing error of just a few billionths of a second could cause a missile to miss its target.
