The Application of NTP to Navy Platforms

Karen F. O'Donoghue, David T. Marlow

Abstract:	Navy platforms consist of many systems ranging from navigation and ship control to tactical analysis, sensors, and weapons. These systems, each composed possibly of multiple computing elements, are inherently time-dependent. In addition, modern surface ships are quickly adding additional COTS based computing elements and communication networks to address emerging requirements, Vital to making such a distributed system function in this environment is a stable robust time service. The Navy has been investigating various methods for the provision of a time service on shipboard platforms. This paper presents an overview of previous Navy efforts, a discussion of the metrics identified as applicable to the Navy environment, and a summary of the HiPer-D time synchronization subnet performance. In addition, this paper identifies ongoing and future work required to provide a stable robust time service in a shipboard environment.
