Providing GPS-quality timing accuracy without GPS

Robust Optical Clock Network (ROCkN)

Synchronizing time in modern warfare – down to billionths and trillionths of a second – is critical for mission success. High-tech missiles, sensors, aircraft, ships, and artillery all rely on atomic clocks on GPS satellites for nanosecond timing accuracy. A timing error of just a few billionths of a second can translate to positioning being off by a meter or more. If GPS were jammed by an adversary, time synchronization would rapidly deteriorate and threaten military operations.
