Omega Stations Stress Timing, Stability
Monrovia, Liberia—Precise frequency control and monitoring facilities to maintain reliability and exact synchronization of all transmitted signals are prime elements in the design of an Omega navigation system ground station. At the Liberian station here, for example, the timing and control center, housed in an environmentally controlled inner chamber, incorporates quadruple caesium beam frequency standards maintained to an accuracy of one part in 10-10, according to Milton E. Boyce, senior technician at the station.
