Field Operations With Cesium Clocks in Hf Navigation Systems

E.H. Christy, D.A. Clayton

Abstract:	For over 10 years, Offshore Navigation, Inc. (ONI) has operated and maintained networks of HF phase comparison marine navigation stations employing cesium clocks. The largest permanent network is in the Gulf of Mexico where some fourteen base stations are continuously active and others are activated as needed. As these HF phase comparison systems, which operate on a single transmission path, require a clock on the mobile unit as well, the ONI inventory consists of upwards of 70 clocks from two different manufacturers. The maintenance of this network as an operating system requires a coordinated effort involving clock preparation, clock environment control, station performance monitoring and field service.
