DARPA’s ROCkN Program Targets GNSS-Free Precision Timing in Contested Environments - Inside GNSS - Global Navigation Satellite Systems Engineering, Policy, and Design

Robust Optical Clock Network aims to deliver shoebox-scale and transportable optical clocks with months-long GPS-quality holdover for next-generation PNT and sensor networks. DARPA has outlined new details of its Robust Optical Clock Network (ROCkN) program, describing how high-precision optical clocks could allow U.S. forces to retain GPS-grade positioning, navigation and timing (PNT) in contested environments while also enabling timing precisi…
